RSPAN through LAG

eyeV — Wed, 03 Jun 2015 13:35:00 GMT

Hi everybody.

I'm stuck with RSPAN configuration. I have three switches (image below). I'd like to configure RSPAN through.

enable sharing 25 grouping 25-26 algorithm address-based L2
Is it right configuration?
create mirror "RSPAN"
configure mirror RSPAN to port 25 remote-tag 99
configure mirror RSPAN add port 20 ingress-and-egress
Or I should do something like?
create mirror "RSPAN"
configure mirror RSPAN to port 25,26 loopback-port 24 remote-tag 99
configure mirror RSPAN add port 20 ingress-and-egress
Moreover, I got this message when I tried to use second configuration example.
Error: Port 25 cannot be added to VMAN as untagged because the port is a tagged VMAN member and a tagged VLAN member.
Mirror-to ports could not be added to mirroring VMAN!

Because port 25 and 26 are an MLAG they are logically 1 single port. I think you should be able to your first option.

Unfortunately no.
# enable mirror "RSPAN"
Error: Port mirroring cannot be enabled on a trunk member port 25

From User Guide 15.7
"A mirror port cannot be a LAG."
It's from limitations.

Thank you!

Thanks. I've read User Guide 15.4.
