Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

 

Command

Purpose

Step 5

 

 

Router(config-if)# h323 gatekeeper [id

Specifies the gatekeeper associated with a proxy and

 

gatekeeper-id] {ipaddr ipaddr [port] multicast}

controls how the gatekeeper is discovered.

 

 

The keywords and arguments are as follows:

 

 

id gatekeeper-id—(Optional) Specifies the

 

 

gatekeeper name. Typically, this is a Domain

 

 

Name System (DNS) name, but it can also be a

 

 

raw IP address in dotted form. If this parameter

 

 

is specified, gatekeepers that have either the

 

 

default or the explicit flags set for the subnet of

 

 

the proxy will respond. If this parameter is not

 

 

specified, only those gatekeepers with the default

 

 

subnet flag will respond.

 

 

ipaddr ipaddr [port]—If this parameter is

 

 

specified, the gatekeeper discovery message will

 

 

be unicast to this address and, optionally, to the

 

 

port specified.

 

 

multicast—If this parameter is specified, the

 

 

gatekeeper discovery message will be multicast

 

 

to the well-known Registration, Admission, and

 

 

Status (RAS) multicast address and port.

Step 6

 

 

Router(config-if)# h323 qos {ip-precedence value

Enables quality of service (QoS) on the proxy.

 

rsvp {controlled-load guaranteed-qos}}

The keywords and arguments are as follows:

 

 

 

 

ip-precedencevalue—Specifies that Realtime

 

 

Transport Protocol (RTP) streams should set

 

 

their IP precedence bits to the specified value.

 

 

rsvp [controlled-load]—Specifies controlled

 

 

load class of service.

 

 

rsvp [guaranteed-qos]—Specifies guaranteed

 

 

QoS class of service.

Step 7

 

 

Router(config-if)# ip route-cache[cbus]

Controls the use of high-speed switching caches for

 

same-interface [flow] distributed

IP routing.

 

 

The keywords are as follows:

 

 

cbus—(Optional) Enables both autonomous

 

 

switching and fast switching.

 

 

same-interface—Enables fast-switching packets

 

 

to back out through the interface on which they

 

 

arrived.
