  • 1.  Packet capture on a MPLS network

    Posted 07-19-2023 12:13


    I have a couple of SRX300 acting as PEs on which i would like to perform a packet capture. I especially want to capture packets related to a xconnect i created between a SRX300 and a Cisco ISR. On each access side of both PEs i have a host.

    I would like the packet capture to be performed on the mpls interface (towards the backbone) of one SRX300 so i can sample a couple of frames including some that brings a simple ping i am performing between the two hosts connected to each other thanks to the L2circuit.

    I tried a couple of scenario but none of them helped.

    Thanks in advance for your kind help.

    Here is the kb on setting up packet capture for branch SRX devices.
