3Com MSR 50, MSR 30 manual 347

347

backup backup-address: Creates a backup remote peer with the IP address of ip-address; backup-addressis the IP address of the primary remote peer, which must be created prior to this backup remote peer.

keepalive-interval: Interval in seconds between keepalive messages, in the range of 0 to 1,200. The default is 30 seconds. A value of 0 indicates no keepalive will be sent.

minutes: Timeout time of the backup connection after the primary remote peer is disconnected, in units of minutes. The effective range is 0 to 1,440, and the default is 5 minutes. A value of 0 means that the backup remote peer will be kept connected after the primary remote peer is disconnected.

max-frame-size: Maximum frame size in bytes. Valid values include 516, 1,470, 1,500, 2,052, 4,472, 8,144, 11,407, 11,454, and 17,800. The default is 1,500 bytes.

max-queue-length: Size of the TCP input/output queue, in the range of 50 to 2,000. The default is 200.

priority: Transmission priority, in the range of 1 to 5. The default is 3.

Description Use the dlsw remote command to create a remote DLSw peer.

Use the undo dlsw remote command to remove a remote peer.

After a local peer is created, a remote DLSw peer should be created to establish a TCP connection. The following command specifies the IP address of the remote router with which a TCP connection is to be established. After the configuration, the router will keep attempting to establish a TCP connection with the remote router. A router can have multiple remote peers.

Note that:

■Before creating a backup remote peer connection, make sure that a primary remote peer has been created.

■If a backup link exists after the primary link is disconnected from the TCP connection, the TCP link remains connected (you can see that a TCP connection exists by using the display dlsw remote command) until the backup link times out.

Example # Create a remote DLSw peer with the following parameters:

■IP address: 2.2.2.2

■Transmission priority: 2

■Keepalive interval: 40 seconds

■Maximum frame size: default

■Size of TCP input/output queue: 300
