Configuring Channelized AU-4 Interfaces

To configure a channelized AU-4 interface, include the partition, oc-slice, and interface-type statements at the [edit interfaces cstm4-fpc/pic/port] hierarchy level, specifying the cau4 interface type:



[edit interfaces cstm4-fpc/pic/port]

partition partition-number oc-slice oc-slice-range interface-type cau4;

This configuration creates interface cau4-fpc/pic/port:channel.

The partition number is the sublevel interface partition index. For SDH interfaces, the partition number is not correlated with bandwidth size. A channelized STM-4 interface can have 1 through 4 partition numbers.

Note: For channelized OC12 interfaces, channel numbering begins with 0 (:0). For channelized OC12 IQ interfaces, channel numbering begins with 1 (:1).

The OC-slice range is the range of SONET/SDH slices. For SDH interfaces, the OC-slice range specifies the bandwidth size required for the interface type you are configuring. Channelized AU-4 IQ interfaces must occupy three consecutive OC slices per interface, in one of the following forms:

1–3
4–6
7–9
10–12

The interface type is the channelized interface type or data channel you are creating.

Example: Configuring Channelized AU-4 Interfaces

Configure channelized AU-4 interfaces, using partitions 1 through 4:



[edit interfaces cstm4-0/2/0]
partition 1 oc-slice 1-3 interface-type cau4;
partition 2 oc-slice 4-6 interface-type cau4;
partition 3 oc-slice 7-9 interface-type cau4;
partition 4 oc-slice 10-12 interface-type cau4;

This configuration creates the interfaces cau4-0/2/0:1 through cau4-0/2/0:4.
