ERSPAN on C9200

[gmlucco]

Hi

I'm trying to implement ERSPAN on a C9200 Switch. This command reference seems to suggest, that this command should be available:

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9200/software/release/16-10/command_reference/b_1610_9200_cr/b_1610_9200_cr_chapter_01000.html

However, when I try to apply the command, it is not recognized.

switch(config)#monitor session 1 type erspan-source
                                 ^
% Invalid input detected at '^' marker.

switch(config)#monitor session 1 ?
  destination SPAN destination interface or VLAN
  filter SPAN filter VLAN
  source SPAN source interface, VLAN

This is my SW Version and SW Image:

Switch Ports Model              SW Version        SW Image              Mode
------ ----- -----              ----------        ----------            ----
*    1 32    C9200-24P          16.11.1           CAT9K_LITE_IOSXE      INSTALL

What am I missing? Thanks for your support.

Hi
You need DNA advantage for erspan

That's a shame. Thanks for the quick answer.

Makes complete sense, from a technical point of view, right? :)

It would be such a useful feature for in depth troubleshooting at our branch locations - especially with WAN bandwidth becoming less and less of a concern. Probably too useful to be included in the basic SW image :o

I could understand the embedded wireshark feature only being available with "Advantage", but ERSPAN feels like it should be available on the platform by default. Oh well...

Hello,

have you been able to configure ERSPAN on your C9200 switch?

I am running the following model with DNA Advantage license

Switch Ports Model          SW Version SW Image         Mode 
------ ----- -----          ---------- ----------       ---- 
* 1    28    C9200L-24T-4X  16.12.02   CAT9K_LITE_IOSXE INSTALL

 and the ERSPAN support is not there

Switch(config)#monitor session 1 ?
  destination SPAN destination interface or VLAN
  filter      SPAN filter VLAN
  source      SPAN source interface, VLAN

Best Regards,

P.

Hi filopeter

ERSPAN on C9200 is not supported even if the correct license is used.
