I am facing port mirroring issue in my setup. Details of the setup are mentioned below
Stack of 4 catalyst switches WS-C3750X-48P running software 15.0(1) SE3 .Approximately 12 vlans are configured in this setup and port mirroring is done for all vlans with destination configured as single Gig Ethernet port...The setup works fine from mirroring perspective for 3-4 days and after that machine connected to destination port stops getting data.
It has been observed that during the issue, the port configured for mirror destination has lot of packet drop/input errors on the port statistics.
If we configure only TX packet mirroring, it works for 8 -10 days
If we configure TX & RX packet mirroring, it works for 2-3 days
Tried clearing counter on destination port but no success (mirroring doesn’t start)
Tried shut /no shut for the destination port but no success.
Tried restarting the machine connected to destination port but no success
We need to reconfigure the mirroring configuration after removing the mirroring config from the switch. Once the same is done, mirroring starts working.
Want to understand
1-is there any HW limitation for the switch (destination port not capable of handling mirroring traffic)
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
