The number of discarded packets on the MA5600T increases

Hi friend.

Generally, a GE or 10GE upstream port discards packets. The packet type cannot be queried by running commands on the device. The specific packet type needs to be analyzed by the mirrored packet. The common packet types are as follows:

1. The upstream port receives packets with mismatched VLAN IDs. That is, the upstream port is not configured with the transparent transmission of the VLAN IDs in the packets.

2. Unknown packets (unknown unicast packets and unknown multicast packets) are suppressed and discarded.

3. The multicast program cannot find the member port. That is, the multicast program is statically added but no user orders the program. You can check the configuration to determine whether the multicast program can be found.

Thanks.
