Beginning with Cisco NX-OS Release 9. Step 3: Verify ERSPAN is handy to be able to do ad-hoc troubleshooting when you need to a packet capture from a remote device, so I configured an erspan-source session to capture ERSPAN on the N9K will not allow you to see any packets captured on the switch itself - The idea of ERSPAN is to encapsulate the "replicated" traffic in GRE and send it to a If anyone has a working ERSPAN config between two nexus 7k switches or between two nexus switches, can I take a look? I seem to be having some difficulties The Cisco NX-OS system supports the Encapsulated Remote Switching Port Analyser (ERSPAN) feature onboth source and destination ports. 9. I always create a dedicated vrf to fully manage the routing between the source and destination ERSPAN and to split it from the other production traffic. The information in this document is based on Nexus 3000, Nexus 5000, and Nexus 7000 switches. Enhancements include more efficient allocation of bandwidth to SPAN and ERSPAN traffic whereby any fabric bandwidth not used for data traffic can be allocated to SPAN or ERSPAN hi out there - i have got the need to forward a RSPAN'ed vlan to a ERSPAN'ed destination. mpls strip 1. The Cisco NX-OS system supports the Encapsulated Remote Switching Port Analyser (ERSPAN) feature onboth source and destination ports. Use ERSPAN on the N9K will not allow you to see any packets captured on the switch itself - The idea of ERSPAN is to encapsulate the "replicated" traffic in GRE and send it to a destination (your laptop, for example) where you'd be running Wireshark and would see/review the captures there. ERSPAN and ERSPAN ACL sessions are terminated identically at the destination router only when the ERSPAN destination IP address is resolved through Cisco Nexus 9300 Series switch ALE 40G uplink ports. 10. SPAN / traffic mirroring / port mirroring is used for many purposes, below includes some. And this looked simpel to me because the NX9k pr default has this feature ERSPAN activated But - when I try to bring-up the tunnel I get this error: # sh mon ses 1 session 1 --------------- type : erspan-sour Hi board, is setting up and running ERSPAN a "dangerous" thing to do on a Cat9k switch?

This limitation might also apply to Cisco Nexus 9500 Series switches, depending on the SPAN or ERSPAN source's If the ERSPAN destination is reachable from any other slice, this ERSPAN-encapsulated packet is fed back to the parser (the ingress pipeline) of the same slice and takes a normal forwarding path, but this time the Nexus 9000 EX/FX/FX2/FX3/GX series support only the forwarding drops, while Nexus 9000 GX2 series supports both forwarding drops Cisco Nexus 9300-EX/FX switches cannot serve as an ERSPAN destination for Cisco Nexus 3000 and non-EX/FX Cisco Nexus 9000 switches. When a session is configured through the ERSPAN configuration commands, the session ID and the session type cannot be changed. 10. VLAN ERSPAN monitors only the traffic that leaves or enters Layer 2 ports in the VLAN. ePub - Cisco Nexus 7000 Series NX-OS System Management Configuration Guide .
