Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

Configuring Gatekeeper Triggers for Interaction with External Applications

To establish statically configured triggers on a router, use the following commands beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

Router(config)# gatekeeper

Enters gatekeeper configuration mode.

Step 2

 

 

Router(config)# server trigger

Configures a static server trigger for external

 

{arq lcf lrj lrq rrq urq} gkid priority

applications. Enter the all form of the no server trigger

 

server-id server-ip-address server-port

all command to remove every static trigger that you

 

 

 

 

configured if you want to delete them all.

 

 

The keywords and arguments are as follows:

 

 

• all—Deletes all command-line interface- (CLI-)

 

 

configured triggers.

 

 

• arq, lcf, lrj, lrq, rrq, urq—Specifies Registration,

 

 

Admission, and Status (RAS) message types. Use

 

 

these message types to specify a submode in the

 

 

gatekeeper configuration mode where you configure

 

 

a trigger for the gatekeeper to act upon. Specify only

 

 

one message type per server trigger command. There

 

 

is a different trigger submode for each message type.

 

 

Each trigger submode has its own set of applicable

 

 

commands.

 

 

• gkid—Specifies the local gatekeeper identifier.

 

 

• priority—Specifies the priority for each trigger. The

 

 

range is from 1 through 20, with 1 being the highest

 

 

priority.

 

 

• server-id—Specifies the identification (ID) number

 

 

of the external application.

 

 

• server-ip-address—Specifies the IP address of the

 

 

server.

 

 

• server-port—Specifies the port on which the

 

 

Cisco IOS gatekeeper listens for messages from the

 

 

external server connection.

Step 3

 

 

Router(config)# info-only

Indicates to the Cisco IOS gatekeeper that messages that

 

 

meet the specified trigger parameters should be sent as

 

 

notifications only and that the Cisco IOS gatekeeper

 

 

should not wait for a response from the external

 

 

application.
