RSPAN C9350

[roniberger123]

Hi,

I have C9350 17.18.02 smart switch that is connected directly to IDS and I have a few C9200 I want all of them vlans to be monitored.
C9350 not supporting the remote-span command.
Which solution I can use?

Thanks in advance, Roni

Hi,

Thanks for your response.

The issue I’m facing is that on my Cisco Catalyst 9350 (running 17.18.02), when I create an RSPAN VLAN (for example, VLAN 301), I do not have the option to configure it with the remote-span command.

It seems like the command is not available under VLAN configuration, so I’m unable to mark the VLAN as an RSPAN VLAN.

Hello @roniberger123, now your question is clearer.

As per this Cisco documentation you're doing the right thing, not sure why is not a valid.

Configuration Examples for SPAN and RSPAN

You can try just specify the RSPAN VLAN and see if works.

SW(config)#monitor session 1 destination remote vlan ?
  <1006-4094>  Remote SPAN destination extended RSPAN VLAN number
  <2-1001>     Remote SPAN destination RSPAN VLAN number
