347
backup backup-address : Creates a backup remote peer with the IP address of
ip-address ; backup-address is 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
