Interface Numbering
Numbering Rule of Service Interfaces on the NE20E-S8
Service interfaces on the NE20E-S8 are numbered in the following format: 0/subcard slot
number/interface number on the subcard.
A subcard slot number is the number of the slot where an interface's subcard resides. A
subcard slot number ranges from 1 to 8.
An interface number on the subcard starts with 0, and its maximum value is determined
by the actual number of interfaces on the subcard.
The following figure shows how a service interface is numbered on the NE20E-S8.
