Hi all,
On the AR, interfaces are numbered in the format of slot ID/subcard ID/interface sequence number.
The slot ID identifies in which slot a card is installed.
The slot ID of the SRU is 0.
When slots need to be combined into one slot, a larger slot ID is used as the new slot ID. For example, when slot 1 and slot 2 are combined, slot ID 2 is used as the new slot ID.
The subcard ID specifies the ID of a subcard. The AR does not support subcards. Therefore, the subcard ID of the AR is always 0.
The interface sequence number indicates the sequence number of an interface on the AR.
There is only one row of interfaces on a card. These interfaces are numbered from left to right starting with 0.
There are two rows of interfaces on a card. These interfaces are numbered from top to bottom and left to right starting with 0.
