Reference Guide
logic is not changed. Because Zero is reserved for logical interfaces, it starts from 1. For the ๎rst 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 4 for 0/3.
Example of Deriving the Interface Index Number
Dell#show interface tengig 0/2
TenGigabitEthernet 0/2 is up, line protocol is up
Hardware is Dell Force10Eth, address is 00:01:e8:0d:b7:4e
Current address is 00:01:e8:0d:b7:4e
Interface index is 72925242
[output omitted]
Monitor Port-Channels
To check the status of a Layer 2 port-channel, use f10LinkAggMib (.1.3.6.1.4.1.6027.3.2). In the following example, Po 1 is a switchport
and Po 2 is in Layer 3 mode.
NOTE: The interface index does not change if the interface reloads or fails over. If the unit is renumbered (for any
reason) the interface index changes during a reload.
