Note that the session is administratively disabled by default and must be manually no shut to start the capture. monitor erspan origin ip-address 1.1.1.1 global . Encapsulated Remote Switched Port Analyzer (ERSPAN) is a technique to mirror traffic over L3 network. Origin IP address which is used as the source for the GRE tunnel. Encapsulated Remote SPAN (ERSPAN) identifies visibility gaps and vulnerabilities, but using it enables flow data to passively monitor on one or more ports or VLANs, and then sends traffic to the target destination. We need to designate Lo1 as the origin IP address for the GRE tunnel. How to Setup the ERSPAN On the device where you want to run the capture enter global config mode and enter the following: monitor session 1 type erspan-source source interface Te1/0/1 destination erspan-id 5 ip address 10.1.1.10 origin ip address 10.1.1.1 The session number is simply the monitor session and can be any available session. ERSPAN transports mirrored traffic over an IP network and ensures better network reliability and availability. You should see something like this: switch_1 (config)# monitor erspan origin ip-address 10.254.254.21 global !--- SPAN is used for troubleshooting connectivity issues and calculating network utilization and performance, among many others. Switch port Analyzer (SPAN) is an efficient, high performance traffic monitoring system. Capturing ERSPAN Traffic with Wireshark We are going to capture and analyze ERSPAN traffic with Wireshark packet sniffer. For Router2, the session type will be erspan-destination, and the source will be configured using the 'source' command: ERSPAN source options include elements such as: Ethernet ports and port channels Switch1 (config-mon-erspan-src-dst)# origin ip address 172.16.10.10 < ip address on switch 1 Switch2 Switch2_Remote (config)# monitor session 1 type erspan-destination Switch2_Remote (config-mon-erspan-dst)# destination interface fa0/5 Switch2_Remote (config-mon-erspan-dst)# source Switch2_Remote (config-mon-erspan-dst-src)# erspan-id 110 Configuring ERSPAN This module describes how to configure Encapsulated Remote Switched Port Analyzer (ERSPAN). At the destination router, the packet is de-capsulated and sent to the destination interface. Optional: you can specify attributes like the ToS (Type of Service), TTL, etc. ERSPAN Types ERSPAN Sources The traffic is encapsulated at the source router and is transferred across the network. Specify the vrf that ERSPAN will use to route to the destination IP !

In this lesson, we will learn to configure ERSPAN in Nexus switches. It directs or mirrors traffic from a source port or VLAN to a destination port. Our source configuration is almost complete, but an additional global command is necessary for ERSPAN to function. A ToS or TTL can also be assigned to the ERSPAN traffic using the 'erspan {tos <tos-value> | ttl <ttl-value>}' command in global configuration mode. So far, we've touched on the need in some environments for a probe, as well the ability to configure and use . Traffic will be encapsulated at the source end and then decapsulated at the destination end. For the destination we have to specify: Unique session ID, doesn't have to match with the source session. Destination switch config: monitor session 4 type . The command used is 'origin ip address <ip-address>'. erspan-id 1 mtu 1464 ip address 10.230.10.1 origin ip address 10.230.10.2 You also must issue the command no shutdown after the command monitor session 1 type erspan-source in order to activate session. ERSPAN transports mirrored traffic over an IP network using the following process: A source router encapsulates the traffic and sends the packet over the network. monitor erspan origin ip-address 10.1.2.1 global On your Sniffer PC running Wireshark, you'll want to configure a Capture Filter that limits the captured traffic to IP Protocol number 47, which is GRE. Note The ERSPAN feature is not supported on Layer 2 switching interfaces. Destination interface (s) where you want to forward the traffic to. The remote IP is the Catalyst 9500 address.
