Does anyone know off-hand how the ports are grouped together on the backplane/motherboard? I'm wondering as I have a switch that the first 2 ports of each 4-plex (1&2, 5&6, 9&10) are giving crc errors, input errors, and flapping for no reason we can determine. Seems odd that other 6 ports are operating normally.
I think it's 4 ports per asic, but you can use the following command to check:
show platform pm if-numbers
The port column shows the asic that the port is attached to.
