Figure 30-28. Binary Representation of Interface Index

For interface indexing, slot and port numbering begins with binary one. If the Dell Force10 system begins

slot and port numbering from 0, then binary 1 represents slot and port 0. In S4810, the first interface is 0/0,

but in the MXL Switch the first interface is 0/1. Hence, in the MXL Switch 0/0s ifindex is unused and

Ifindex creation logic is not changed. Since Zero is reserved for logical interfaces, it starts from 1. For the

first interface, port number is set to 1. Adding it causes an increment by 1 for the next interfaces, so it only

starts from 2.Therefore, the port number is set to 42 for 0/41.

Note that the interface index does not change if the interface reloads or fails over. If the unit is renumbered

(for any reason) the interface index will change during a reload.

Monitor Port-channels

To check the status of a Layer 2 port-channel, use f10LinkAggMib (.1.3.6.1.4.1.6027.3.2). Below, Po 1 is a

switchport and Po 2 is in Layer 3 mode.
