4000 Router Series Interface Configuration Guide

Displaying and maintaining POS interfaces

Execute display commands in any view and reset commands in user view.

Task Command

Display information about one or

all POS interfaces.

display interface [ pos ] [ brief [ down ] ]

display interface [ pos [ interface-number ] ] [ brief [ description ] ]

Clear statistics of one or all POS

Configuration example for directly connecting

routers through POS interfaces

Network requirements

As shown in Figure 2, use a pair of single mode optic fibers (for receiving and sending data, respectively)

to connect the POS interfaces on Router A and Router B.

Encapsulate the interfaces with PPP.

Configuration procedure

1. Configure Router A:

# Configure interface POS 1/0, setting its physical parameters to defaults.

<RouterA> system-view

[RouterA] interface pos 1/0

[RouterA-Pos1/0] ip address 10.110.1.10 255.255.255.0

[RouterA-Pos1/0] link-protocol ppp

[RouterA-Pos1/0] mtu 1500

[RouterA-Pos1/0] shutdown

[RouterA-Pos1/0] undo shutdown

2. Configure Router B:

# Configure interface POS 1/0.

<RouterB> system-view

[RouterB] interface pos 1/0

# Set the clock mode to master and other physical parameters to defaults.

[RouterB-Pos1/0] clock master

[RouterB-Pos1/0] ip address 10.110.1.11 255.255.255.0

[RouterB-Pos1/0] link-protocol ppp

[RouterB-Pos1/0] mtu 1500
