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.
