Hi guys
@mkk
- CRC errors are not growing. SFPs and cables look fine. I guess we got them as we plugged the fiber cables.
- About the VLANs: yes we have different VLAN mapping between 8325 and Nexus. Basically the Nexus is allowing all VLANs on the trunk also vlans that are not really used anymore. On the 8325 we are allowing only the VLANs that matter.
Given this I was expecting drops on the ingress (rx) of the interface but i still can't explain the tx drops. Or am I understanding this wrong?
@parnassus
- MTU: Yes I checked. MTU is 1500 on every interface and VLAN of the Nexus. There are no jumbo configurations.
- The output of show lacp interfaces multi-chassis
sw003-dist# show lacp interfaces multi-chassis

- 10G/25G: Correct. The port-group is set to operate at 10Gbps.
Edit:
We have mcast traffic streaming from the nexus and igmp snooping enabled on the vlans streaming mcast traffic. Could the drops be mcast traffic dropped by igmp to avoid mcast traffic going back to the nexus?
