This chapter describes how to configure the Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) on the Catalyst 4500 series switches. Regards, All FortiSwitch models support switched port analyzer (SPAN) mode, which mirrors traffic to the specified destination interface without encapsulation. When we configure a destination port, its original configuration is overwritten. Remote SPAN (RSPAN) port. monitor session 1 source interface Gi1/0/1 – 28 rx. This article provides extra steps for deploying an Enterprise IoT sensor, including a sample SPAN port configuration procedure, and CLI steps to validate your deployment or delete a sensor. The network Updated: May 6, 2007 Bias-Free Language Table Of Contents Configuring SPAN and RSPAN Understanding How SPAN and RSPAN Work SPAN Session Destination Port Source Port Reflector Port Ingress SPAN 1 How to configure port monitoring (SPAN) on a Catalyst 2940, 2950, 2955, 2970, 3550 or 3750 series switch TCC_2 Advocate Options 06-22-2009 03:36 PM - Log in to the switch enter enable mode, and then configure terminal. To summarize, the mirroring is not SPAN Configuration RSPAN Configuration Cisco Catalyst Switches have a feature called SPAN (Switch Port Analyzer) that lets you copy all traffic from a source port or VLAN to Source ports are ports whose data will be copied, and sent to the destination, or SPAN port. If SPAN configuration is removed from the SPAN session, all rules associated with the SPAN destination interface are applied once again. Figure 2. 0 Helpful Reply. Local SPAN does not have separate source and destination sessions. Log into the switch through the CNA interface. Open the OT Sensor VM properties. edit This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on Gigabit Ethernet source port 1, and send it to destination Gigabit Ethernet port 2 with the same egress encapsulation type as the source port, and to enable ingress forwarding with VLAN 6 as This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on Gigabit Ethernet source port 1, and send it to destination Gigabit Ethernet port 2 with the same egress encapsulation type as the source port, and to enable ingress forwarding with VLAN 6 as . Switch(config)#monitor session 1 destination interface GigabitEthernet 0/8. Example of Local SPAN Configuration on a Single Device. If the SPAN Configure a SPAN port on your switch to mirror local traffic from interfaces on the switch to a different interface on the same switch. You can also configure SPAN source sessions to filter ingress traffic (Rx) by using VLAN access control lists (VACLs). com is not required. There's no real config need on UCS to accomplish this. A monitor port is actually a destination SPAN port in Catalyst 2900XL/3500XL terminology. To access Cisco Feature Navigator, go to http://www. You’ll only need two commands to set up a SPAN port configuration. For SPAN sources, you can monitor traffic for a single port or VLAN or a series or range of ports or VLANs for each session. Description. set span enable. Select the SPAN check box, then select a source port from which traffic will be mirrored. To remove a source or destination port from the SPAN session, use the no monitor session session_number source interface interface-id global configuration command or the no monitor session session_number destination interface interface-id global configuration command. This article provides sample SPAN ( Switched Port Analyzer) is a Cisco-specific way of handling port mirroring. Switch1# configure terminal. This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on Gigabit Ethernet source port 1, and send it to destination Gigabit Ethernet port 2 with the same egress encapsulation type as the source port, and to enable ingress forwarding with VLAN 6 as Configure a SPAN port on your switch to mirror local traffic from interfaces on the switch to a different interface on the same switch. Switch1# configure terminal Switch1 (config)# monitor session 1 As per your configuration if the device is connected to Te2/1/4 you want to capture all the information or span that port as source. The configuration is then modified to also monitor all traffic on all ports belonging to VLAN 10. When you configure a port or EtherChannel as a SPAN destination, it is dedicated for use only by the SPAN feature. To mirror port gi0/1 I’ll use the command below. set vdom <vdom-name> --> Enter the name of the VDOM, if no VDOMS are configured then it will be root. More information. Until the configuration of SPAN on switch, the frames flow normally from PC to server and vice-versa. When ports are spanned for monitoring, the port state shows as UP/DOWN. For Network Adapter 2, select the SPAN network. port 10receives all network traffic from port 5 without being physically attached to port 5. The virtual SPAN session copies traffic from the three VLANs to the three specified destination ports. From CLI access to standalone FortiSwitch using SSH/TeraTerm. To configure a SPAN monitoring interface: On your vSwitch, open the vSwitch properties and select Add > Virtual Machine > Next. Connect to the sensor, and verify that When SPAN / Ethanalyzer is used to capture the traffic on PV enabled ports, only the incoming 802. edit <port>. In such cases, the following global configuration command is used: monitor session <session-id> destination interface <interface-id> ingress {dot1q vlan <vlan-id> | untagged vlan <vlan-id>} This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on all ports belonging to VLANs 1 through 3, and send it to destination Gigabit Ethernet port 2. SPAN and have the same configuration commands. You configure a local SPAN session on a single switch. No network link interruption. Switch Configuring a Source Rate Limit for Each SPAN Session When a SPAN session is configured with multiple interfaces or VLANs as the sources in a high-traffic The actual configuration of SPAN is pretty simple. and where your capture recorded Up to 64 SPAN destination ports can be configured on a switch. The SPAN or mirror port permits the copying of traffic from other ports on the switch. • Designed for low-throughput spot checking. For This chapter describes how to configure the Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) on the Catalyst 4500 series switches. For the purposes of our discussion, we can use these terms interchangeably, Local SPAN Configuration The source ports are specified by entering the following command in the global configuration: 'monitor session <session-id> source {interface SPAN Destination Port Up/Down. All traffic on port 5 (the source port) is mirrored to port 10 (the destination port). Now exit the configuration mode using the end command, then check if the span port configuration was a Figure 1. Defender for IoT supports the following methods: Method. Note For complete syntax and usage information for the When you configure a device port as a SPAN destination port, it is no longer a normal device port; only monitored traffic passes through the SPAN destination port. 2(33)SXH and later releases, an EtherChannel, to which local SPAN, RSPAN, or ERSPAN sends traffic for analysis. Entering SPAN configuration This chapter describes how to configure Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) on the Catalyst 2960 switch. Select the destination port to which the mirrored traffic is sent. Before configuring a SPAN port, it’s a good idea to see if any already exist on your switch by using the command below. You can choose which VLANs to allow on each destination Configuring SPAN and RSPAN ThischapterdescribeshowtoconfigureSwitchedPortAnalyzer(SPAN)andRemoteSPAN(RSPAN). Packets entering or exiting a VLAN. Tap mode deployment allows you to passively monitor traffic flows across a network by way of a switch SPAN or mirror port. For example, you can configure SPAN on a trunk port and monitor traffic from different VLANs on different destination ports. SPAN is for mirroring traffic on the same switch, so you'll need to use an Encapsulated Remote-SPAN (ERSPAN). Note For complete syntax and usage Configuring Local SPAN: Local SPAN configures using “monitor session” command specifying source and destination on the same switch. set member “port no” “port no” --> These are the ports that you want to add to your span port configuration. # config switch mirror. Example of Local SPAN Configuration on a Device Stack. To quickly configure local port mirroring of traffic from the two ports connected to employee computers, filtering so that only traffic to the external Web is mirrored, copy the following commands and paste them into the switch terminal window For example, you can configure SPAN on a trunk port and monitor traffic from different VLANs on different destination ports. Port mirroring is used on a switch to send a copy of packets seen on one switch port (or an entire VLAN) to a monitoring connection on another switch port. View solution in original post. Local SPAN sessions do not copy locally sourced RSPAN VLAN traffic from source trunk ports that carry RSPAN VLANs. Assigns the exit port to use for the specified mirroring session. First, any existing SPAN configuration for session 1 is deleted, and then A SPAN destination is a Layer 2 or Layer 3 port or, with Release 12. G0/0/0 --dot1q-- ASR1002 ----G0/0/2. 2. Enthusiast SPAN for soft switch can be enabled in the CLI: # config system switch-interface. A network analyzer on port 10 receives all network traffic from port 5 without being physically attached to port 5. This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on Gigabit Ethernet source port 1, and send it to destination Gigabit Ethernet port 2 with the same egress encapsulation type as the source port, and to enable ingress forwarding with VLAN 6 as Ingress source (Rx)—Traffic entering the device through this source port is copied to the SPAN destination port. You can choose which VLANs to allow on each destination The SPAN configuration from the 3850 is like below, #show monitor Session 1-----Type : Local Session Source Ports : Both : Gi1/1/2 If the source port and destination port are in the same switch, use SPAN. The above Source (SPAN) VLAN: A VLAN whose traffic is monitored Destination (SPAN) port: A port that monitors source ports. Go to solution. This will display a graphic representing the port array of the switch. SPAN session can be Configuration Guidelines. SPAN Configuration Guidelines. mirror-port <PORT-NUM> no mirror-port <PORT-NUM>. Step 2: Configure Open the Port Group properties page and select Add Port Group. SPAN. Enter SPAN Port Group as the name, enter 4095 as the VLAN ID, and select SPAN Network in the vSwitch drop down, then select Add. Select OK. Figure 23-1 Example of Local SPAN Configuration on a Single Switch Remote SPAN RSPAN supports source ports, source VLANs, and destination ports on different switches, enabling remote monitoring of multiple switches across your network. cisco. Switched Port Analyzer Configuration Guidelines. monitor session 1 source interface gi0/1. A network tap is a device that provides a way to access data flowing across a computer network. To remove a source or destination port or VLAN from the SPAN session, use the no monitor session session_number source {interface interface-id | vlan vlan-id} global configuration command or the no monitor session session_number destination interface interface-id global Figure 1. Port mirroring is used to analyze and debug data or diagnose errors on a network. Port Mirroring Interoperability. When you configure port mirroring, depending upon your hardware, you can mirror: • select ports or select VLANs from a device to a monitoring port. This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on Gigabit Ethernet source port 1, and send it to destination Gigabit Ethernet port 2 with the same egress encapsulation type as the source port, and to enable ingress forwarding with VLAN 6 as Juniper Networks devices allow you to configure port mirroring to send copies of packets to either a local interface for local monitoring or to a VLAN or bridge domain for remote monitoring. show monitor session all Step 1: Configure Source SPAN Port. Restrictions for SPAN SPAN The restrictions for SPAN are as follows: For SPAN sources, you can monitor traffic for a single port or a The Switched Port Analyzer (SPAN) feature (sometimes called port mirroring or port monitoring) selects network traffic for analysis by a network analyzer. An account on Cisco. This is usually the point to which a Switch Port Analyzer (SPAN) is switch specific tool that copies Ethernet frames passing through switch ports and send these frames out to specific port. The no form of the command removes the mirroring session and any mirroring source previously assigned to that session. Use the same parameters (source ip address, source udp port, destination ip address) employed in the source switch configuration, and assign the mirroring port (where your IDS is connected): mirror endpoint ip src-ip src-udp-port dst-ip port exit-port-# References: Aruba 3810 / 5400R Management and Configuration Guide for ArubaOS For this configuration, set the physical interface as the ERSPAN source. Compare supported traffic mirroring methods. switch-vtep-2(config)# interface port-channel 10 switch-vtep-2(config-if)# vpc 10 switch-vtep-2(config-if) I would suggest creating a dedicated second vNIC on your destination VM on the appropriate VLAN and assigned with the proper IP. Switch1 (config)# monitor session 1 source interface FastEthernet 0/1 both. When you configure a SPAN session to monitor Hello, I'm trying to configure SPAN on my Cisco Catalyst 3560 in order to be able to mirror traffic from one port to another. • Provide access to packets for monitoring. Configure mirroring with a switch SPAN port. There are some interoperability issues to consider when using vSphere Select the SPAN check box, then select a source port from which traffic will be mirrored. STEPS TO CONFIGURE PORT MIRRORING ON A STANDALONE FortiSwitch. If they're in different switches, use RSPAN. You must execute command from the global configuration level. On the ERSPAN destination, disable the VLAN filter with the plim ethernet vlan filter disable command. The only thing left to do is to find a free port you Syntax. The first one is: Switch (config)#monitor session 1 source interface This chapter describes how to configure Switched Port Analyzer (SPAN) and on the Catalyst 2960 switch. Mirrors local traffic from interfaces on the switch to a different interface on the same switch. Tap Interfaces. Austin Sabio. If the filter is not disabled, the SPAN session does not send the replicated traffic. A source session is either a local SPAN session or an RSPAN source session. switch (config)# mirror-port A local SPAN session is an association of source port s and source VLANs with one or more destinations. If a SPAN destination port is configured as a trunk port and the VLANs to which it belongs have ACLs associated with them, the traffic is not subjected to the VACLs. You can use the terms SPAN and port mirroring interchangeably. This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on all ports belonging to VLANs 1 through 3, and send it This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on all ports belonging to VLANs 1 through 3, and send it The destination SPAN port usually receives traffic and rejects ingress traffic. The figure below shows a virtual SPAN configuration. First, any existing SPAN configuration for session 1 is deleted, and then bidirectional traffic is mirrored from source Gigabit Ethernet port 1 to destination Gigabit Ethernet port 2, retaining the encapsulation method. Egress source (Tx)—Traffic exiting the device through this source port is copied to the SPAN destination port. This article provides sample configuration processes and procedures for configuring a SPAN port, using either the Cisco CLI or GUI, for a Cisco 2960 switch with 24 ports running IOS. 1q tag is seen in the captured traffic. SPAN can also be enabled in the CLI: config system virtual-switch. SPAN selects network traffic for analysis by a network analyzer, such as a SwitchProbe device or other Remote Monitoring (RMON) probe. Here is a screenshot from my switch. Sometimes, connectivity to the network analyzer may be necessary. the configuration port that you have chosen to be a destination SPAN port; just list the source ports you would like to monitor using the port monitor interface command. com/go/cfn. This chapter consists of the following sections: About This article provides extra steps for deploying an Enterprise IoT sensor, including a sample SPAN port configuration procedure, and CLI steps to validate your deployment or delete a sensor. Click on the port that you want to connect the packet sniffer to and select the Modify option. Figure 1. This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on Gigabit Ethernet source port 1, and send it to destination Gigabit Ethernet port 2 with the same egress encapsulation type as the source port, and to enable ingress forwarding with VLAN 6 as Consider the figure given below containing switch, server, PC and network analyzer. Select to mirror traffic received, traffic sent, or both. On a port VLAN translation enabled port, traffic should not be received in translated VLAN. This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on Gigabit Ethernet source port 1, and send it to destination Gigabit Ethernet port 2 with the same egress encapsulation type as the source port, and to enable ingress forwarding with VLAN 6 as Follow these steps to get SPAN active on the switch. On each switch, you can configure a maximum of 8 source sessions and 58 RSPAN destination sessions. This example shows how to set up SPAN session 1 for monitoring source port traffic to a destination port. from where frames are copied is called Source port and Port out of which copied frames are send is called Destination port. This chapter consists of the following sections: About Port Mirroring also known as SPAN (Switch Port Analyzer), are designated ports on a network appliance (switch), that are programmed to send a copy of network packets seen on one port (or an entire VLAN) to another port, where the packets can be analyzed. Select the Smartports option in the CNA menu. To configure port mirroring for employee to web traffic, perform these tasks: CLI Quick Configuration. A switch SPAN port. You can use mirroring to copy these packets: Packets entering or exiting a port. Port mirroring is commonly referred to as switched port analyzer (SPAN). Enabling SPAN is usually a simple thing to do: you don’t have to unplug any production link (unless all ports are in use and you do not have a free port for the network capture device), and just configure the switch to send copies of a port to the “monitor” port. The port GE0/8 is where the user device is connected.
