Command Reference Guide Frame Relay Interface Config Command Set

frame-relay multilink [ack <seconds> | bandwidth-class <class>

Use the frame-relay multilink command to enable the Frame Relay multilink interface. When the no

form of this command is issued, all configuration options associated with this command and

cross-connects made to this interface are removed.

Syntax Description

ack <seconds> Optional. S pecifies a wait for acknowledgement time (in seconds) for every bundle

link in the bundle. Range: 1 to 180 seconds.

bandwidth-class Optional. Specifies the class of operation, placing a minimum limit on the

acceptable amount of bandwidth required for a bundle to up.

<class> Optional. Specifies the class of operation. Range is A to C:

Class A A single active link is sufficient for the bundle to be up.

Class B All defined bundle links must be active for the bundle to be u p.

Class C A minimum threshold of links must be active for the bundle to be up.

<threshold> Optional. S pecifie s the minimum number of active bundle links r equired for a class

C bundle to be in the up state. This option will not be available unless Class C is

specified. Range: 1 to 65,535 links.

hello <seconds> Optional. Specifies the time (in seconds) between hello messages for every

bundle link in the bundle. Range: 1 to 180 seconds.

retry <number> Optional. Specifies the number of times a bundle link will retransmit a message

while waiting for acknowledgement. Range: 1 to 5 times.

Default Values

The default ack value is 4 seconds. The d efau lt hello value is 10 seco nds. Th e defau lt <class> value is a.

The default retry value is 2.

Applicable Platforms

This command applies to the NetVanta 1000R, 3000, 4000, and 5000 and Total Access 900 Series units.

Command History

Release 9.1 Command was introduced.

Functional Note

This command is different from ppp multilink. In ppp multilink, if multiple cross-connects are configured

for the PPP interface without multilink PPP being enabled, the first link to bring up LCP will be the only link

actually cross-connected. In Frame Relay multilink, since there is no protocol corresponding to LCP, all

cross-connects will be removed and the user will be free to re-issue any cross-connect.
