Have a look at the section "Port MIrroring" in the 7750 SR OS OAM and Diagnostics Guide.

Are you asking how you can match an LLDP frame?
It's not an IP packet so you can't explicitly match it in an IP filter.
You could try a mac-filter, something like:

          mac-filter "100"
              entry 10 create
                  match
                      etype "0x88cc"
                  exit
                  action
                     forward
                 exit
             exit
         exit

Great!
But It says:

Code: Select all

>config>filter>mac-filter>entry# match etype "0x88cc"
MINOR: FILTER #1521 Invalid frame type - E-type cannot be configured/changed.
How should I do :?:

Thank you very much.

Sorry, I forgot the frame-type is mandatory. Try this instead:

configure filter mac-filter "100" create
  entry 10 create
    match frame-type ethernet_II  etype "0x88cc"
    action  forward
