Parameter ip-address: IP address of the local peer to be created. This IP address must be reachable.

init-window-size: Initial local window size, in the range of 1 to 2,000. The default is 40 (frames).

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

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

max-window-size: Maximum local window size, in the range of 1 to 2,000. The default is 50 (frames).

permit-dynamic: Permits non-peer routers to initiate connections to establish peering relationships dynamically with this router. It is not required to configure a remote peer for a router established as a local peer with this keyword included in the command.

vendor-id: DLSw vendor identifier, in the range of 00.00.00 to ff.ff.ff. The default is 00.e0.fc.

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

Use the undo dlsw local ip-addresscommand to remove the specified local

DLSw peer.

Use the undo dlsw local ip-address{ init-window keepalive max-frame max-window permit-dynamic } * command to restore the default parameters.

Deleting a local DLSw peer will automatically delete all its remote DLSw peers.

Establishing a TCP connection is the first step in establishing a DLSw circuit. To establish a TCP connection, you need to specify the IP addresses of both end systems across the TCP connection. By configuring a local DLSw peer, you specify the IP address of the local end across the TCP connection. This is required before a router can initiate or accept a TCP connection request. A router can only have one local peer.
