Howto mirror a mlag in an EAPS ring

JohanHendrikx — Wed, 19 Dec 2018 16:33:00 GMT

I have an EAPS ring with x670-G2-48X switches. Connected at the core there is a MLAG configuration.

How can I mirror both links ?

You could configure remote mirroring:

https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-configure-remote-mirroring/

Or you can try our new L3 Remote mirroring if your using 22.4 and newer:

Remote Mirroring Using Layer 3
To use remote mirroring using Layer 3, enable IPv4 forwarding along the routed path to the device
collecting GRE-encapsulated mirrored packets, also known as ERSPAN. Then, configure the collector
device's IP address as the remote IP adddress in the following command:

code:

enable mirror {mirror_name} to remote-ip remote_ip_address {{vr}
vr_name} {from [source_ip_address | auto-source-ip]} {ping-check [on |
off]}]

Hi Stephen,

Yes, I found this document too. Only….
When I create a mirror at the left switch, there is no vlan configured at the mirror port. According the document i have configure the vlan untagged to that port.

I would probably use remote mirroring in the article i attached. It dumps the traffic into a mirror vlan you create. For the left switch you can use the below command.

configure mirror to port 5 remote-tag
