peer listen-only
Function
The peer listen-only command configures a peer or peer group to only detect connection requests and not to initiatively send connection requests.
The undo peer listen-only command restores the default setting.
By default, a peer or peer group detects and sends connection requests.

Usage Guidelines
Usage Scenario
The peer listen-only command is used to configure a peer or peer group to only detect connection requests and not to initiatively send connection requests.
Prerequisites
Peer relationships have been established using the peer as-number command.
Precautions
If the peer listen-only command is run multiple times, the latest configuration overwrites the previous one.
After the peer listen-only command is executed, the local end does not initiate any connection request to a specified peer.
The peer listen-only command can be run at only one end of a peer relationship. If this command is run at both ends of a peer relationship, the ends fail to establish a connection.
