Could Nokia sniff LLDP packet?
Re: Could Nokia sniff LLDP packet?
Have a look at the section "Port MIrroring" in the 7750 SR OS OAM and Diagnostics Guide.
Re: Could Nokia sniff LLDP packet?
Could you please narrow down to the commands like this
Thank you very much.
Code: Select all
configure filter log 140 create destination memory 4000
configure filter ip-filter 40 create entry 10 create match protocol ip
back
log 140
action forward
back
entry 20 create match protocol icmp
back
log 140
action forward

Re: Could Nokia sniff LLDP packet?
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:

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:
How should I do
Thank you very much.
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.
Thank you very much.

Re: Could Nokia sniff LLDP packet?
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
Re: Could Nokia sniff LLDP packet?
You need to first define a destination for the mirrored traffic then with a debug command, start the mirroring. The simplest is to send the mirrored traffic out of another local port.
For example, to mirror the ingress traffic matching mac-filter 100 entry 10 on source port is 1/1/1 to destination port 2/2/2:

configure mirror mirror-dest "1" create sap "2/2/2" create exit no shutdown exit exit exit debug mirror-source 1 port 1/1/1 ingress mac-filter 100 entry 10 no shutdown exit exit

Could it destination to the log or storage Which I can upload over the VPN to my laptop.

It's not a debug command. I do not believe there is an lldp debug command available.
This is copying the raw packets and sending therm out of another port on the 7750.
You would need to connect a laptop running Wireshark (or another packet capture application) to the destination port.
It is also possible to send the mirrored packets over the network to a remote 7750, but this is obviously a bit more complicated to set up.
