Configuration Roadmap

The configuration roadmap is as follows:

1. Add the user name and password of Switch B to the local user list of Switch A.

2. Configure the local user name for Switch A.

3. Configure Switch A to authenticate the peer in CHAP mode.

4. Configure the local user list on Switch B.

5. Configure the local user name for Switch B.

Data Preparation

To complete the configuration, you need the following data:

l Local user name of Switch A

l Local user name and password of Switch B

l IP address of the interface on Switch A

l IP address of the interface on Switch B

Procedure

Step 1 Configure Switch A.

# Add the username and password of Switch B to the local user list of Switch A.

<Quidway> system-view

[Quidway] sysname SwitchA

[SwitchA] aaa

[SwitchA-aaa] local-user rtb password simple hello

[SwitchA-aaa] quit

# Configure an IP address for POS 1/0/0 and configure the link-layer encapsulation protocol as

PPP.

[SwitchA] interface pos 1/0/0

[SwitchA-Pos1/0/0] ip address 10.110.0.1 255.255.255.0

NOTE

l When you configure an IP address for an interface on a PPP link, if you delete the IP address of the

interface on the PPP link that fulfills the IPCP negotiation and assign this IP address to an interface on

another PPP link, the IPCP negotiation of the later PPP link is definitely unsuccessful. To solve this

problem, you can run the shutdown and undo shutdown commands on the former interface to restore

the IPCP negotiation or assign a new IP address to the later interface.

l When you configure an IP address for an interface on a PPP link, if the configuration is correct but the

negotiation is always unsuccessful, it is recommended that you assign a new IP address to the interface.

[SwitchA-Pos1/0/0] link-protocol ppp

# Configure the local to authenticate the peer in CHAP mode.

[SwitchA-Pos1/0/0] ppp authentication-mode chap

# Configure the local username of SwitchA

[SwitchA-Pos1/0/0] ppp chap user rta
