Hi,

Further to mivens response above, you could create the mac-filter but also log the matching packets to a file or to memory. The below will just be 500 entries in memory.

Try this:

configure filter
log 150 create
destination memory 500
exit
mac-filter 500 create
entry 10 create
match frame-type ethernet_II
etype 0x88cc
exit
log 150
action
forward
exit
exit
exit

Then you can check it:

show filter log 150

Thanks

NB - the default-action of filters is always drop, so either change this to forward (see below), or create a catch all entry too, otherwise traffic will stop on any interface you apply this too.

config filter mac-filter 500
default-action forward

So, I will configure this, right *A:R1# debug
*A:R1>debug# mirror-source 1
MINOR: SVCMGR #3010 Mirror destination does not exist - Svc Id = 1

Thank you very much.

Hi,

No, the filter and the mirror and two different tools.

The MAC filter can be applied to a sevice sap, such as an epipe or VPLS etc. Don;t think you can apply this directly to a port unfortunately though.

So not sure what your network looks like, you may need to use the mirror to capture the packets.

Have you also checked the output of the show command, that has many stats in there for lldp.

show port x/x/x ethernet lldp detail

Thanks

There is Deep packet inspection between the network port which block LLDP between routers. How should I do

Thank you very much.

If the LLDP frames are being blocked by a third-party and you can't get them to change this, then the question is whether there is an alternative way of achieving your aims without it.

What are you trying to achieve / what is the specific problem you are trying to solve?

To take one example, if you are using it to build a L3 topology then you may be able to use IGP adjacency information instead.

Actually, the router sees the LLDP with their mac address instead of another side. They would like me to help them capture packet, what is packet they sent to the router

Thank you very much.
