Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

Command

Purpose

•password separator character—Specifies the character that endpoints use to separate the H.323-ID from the piggybacked password in the registration. This allows each endpoint to supply a user-specific password. The separator character and password will be stripped from the string before it is treated as an H.323-ID alias to be registered.

Note that passwords may be piggybacked only in the H.323-ID, not the E.164 address. This is because the E.164 address allows a limited set of mostly numeric characters. If the endpoint does not wish to register an H.323-ID, it can still supply an H.323-ID that consists of just the separator character and password. This will be understood to be a password mechanism, and no H.323-ID will be registered.

After the previous steps have been completed, enter each user into the RADIUS database using either the default password if using the security password default command or the actual passwords if using the piggybacked password mechanism as the RADIUS authentication for that user. Enter either the user H.323-ID or the E.164 address, depending on how the gatekeeper was configured.

Configuring a RADIUS/AAA Server

To configure the RADIUS/AAA server with information about the gatekeeper for your network installation, use the following commands beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

Router(config)# aaa new-model

Enables the authentication, authorization, and

 

 

accounting (AAA) model.

Step 2

 

 

Router(config)# aaa authentication login {default

Sets AAA authorization at login.

 

list-name}method1 [method2...]

For an explanation of the keywords and arguments,

 

 

 

 

see Step 2 in the configuration task table in the

 

 

“Configuring H.323 Users via RADIUS” section on

 

 

page 314.

Step 3

 

 

Router(config)# radius-server deadtime minutes

Improves the server response time when some servers

 

 

might be unavailable. The minutes argument

 

 

specifies the length of time, in minutes, for which a

 

 

RADIUS server is skipped over by transaction

 

 

requests, up to a maximum of 1440 minutes (24

 

 

hours).
