Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

Command

Purpose

flow—(Optional) Enables the Route Switch Processor (RSP) to perform flow switching on the interface.

distributed—Enables Versatile Interface Processor (VIP) distributed switching on the interface. This feature can be enabled on Cisco 7500 series routers with RSP and VIP controllers. If both the ip route-cache flow command and the ip route-cache distributed command are configured, the VIP does distributed flow switching. If only the ip route-cache distributed command is configured, the VIP does distributed switching.

Table 26 lists interface types that may be used for the type argument in Step 2 of the configuration task table in the “Configuring a Proxy Without ASR” section on page 333.

Table 26 Interface Type Keywords

Keyword

Interface Type

 

 

async

Port line used as an asynchronous interface.

 

 

atm

ATM interface.

 

 

bri

ISDN BRI. This interface configuration is propagated to each of the B channels.

 

B channels cannot be individually configured. The interface must be configured

 

with dial-on-demand commands for calls to be placed on that interface.

 

 

dialer

Dialer interface.

 

 

ethernet

Ethernet IEEE 802.3 interface.

 

 

fastethernet

100-Mbps Ethernet interface on the Cisco 4500, Cisco 4700, Cisco 7000, and

 

Cisco 7500 series routers.

 

 

fddi

FDDI interface.

 

 

group-async

Master asynchronous interface.

 

 

hssi

High-Speed Serial Interface (HSSI).

 

 

lex

LAN Extender (LEX) interface.

 

 

loopback

Software-only loopback interface that emulates an interface that is always up. It

 

is a virtual interface supported on all platforms. The interface-number is the

 

number of the loopback interface that you want to create or configure. There is

 

no limit on the number of loopback interfaces you can create.

 

 

null

Null interface.

 

 

port-channel

Port channel interface.

 

 

pos

Packet OC-3 interface on the Packet over SONET Interface Processor.

 

 

serial

Serial interface.

 

 

switch

Switch interface.

 

 

tokenring

Token Ring interface.
