Cisco IOS Voice, Video, and Fax Configuration Guide
Step 5 Router(config-if)# h323 gatekeeper [id
gatekeeper-id] {ipaddr ipaddr [port] | multicast}
Specifies the gatekeeper associated with a proxy and
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 |
rsvp {controlled-load | guaranteed-qos}}
Enables quality of service (QoS) on the proxy.
The keywords and arguments are as follows:
• ip-precedence value—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]
same-interface [flow] distributed
Controls the use of high-speed switching caches for
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.
