CPOS-E1 interface configuration example

Network requirements

As shown in Figure 14, branch nodes Router B through Router H are uplinked to the central node Router

A through E1 links and Router A aggregate these E1 links with a CPOS interface.

Add one more E1 link on Router B to expand its capacity. In addition, bind the two E1 links through an

MP-group interface.

Configuration procedure

Because the clock source of a SONET/SDH network is more precise than the internal clock source of the

device, when connecting the device to a SONET/SDH device, configure the clock mode of the

SONET/SDH device as master.

1. Configure Router A:

# Configure the E1 channels of CPOS interface CPOS 2/0 to operate in unframed mode.

<RouterA> system-view

[RouterA] controller cpos 2/0/0

[RouterA-Cpos2/0/0] e1 1 unframed

[RouterA-Cpos2/0/0] e1 2 unframed

# Create MP-group 1 and assign an IP address to it.

[RouterA] interface mp-group 1

[RouterA-Mp-group1] ip address 10.1.1.1 24

[RouterA-Mp-group1] quit

# Configure Serial 2/0/0/1:0 and Serial 2/0/0/2:0 and add them to MP-group 1.

[RouterA] interface serial2/0/0/1:0

[RouterA-Serial2/0/0/1:0] ppp mp mp-group 1

[RouterA-Serial2/0/0/1:0] quit

[RouterA] interface serial2/0/0/2:0

[RouterA-Serial2/0/0/2:0] ppp mp mp-group 1

[RouterA-Serial2/0/0/2:0] quit
