H323 commands

azaghul · February 2010

Hi,

Still working my way through CVoice (I really need to get it over with) and have come back to H323 configuration, something is not quite clear (again

).

All the examples show the h323-gateway voip interface command shown under a physical serial/fastethernet interface, but bound back to a loopback interface. Unfortunately the voice command reference is less that helpful. Should it be under fa0/0, fa0/0.10, or fa0/0.50? I'm assuming fa0/0.10.

int loop0
 ip addr 192.168.100.10 255.255.255.0

int fa0/0
 no ip addr
 no shut
int fa0/0.10
 desc *** VOICE VLAN ***
 encap dot1q 10
 ip addr 192.168.10.1 255.255.255.0
 h323-gateway voip interface
 h323-gateway voip h323-id gw1.homenet.net
 h323-gateway voip bind srcaddr 192.168.100.10
int  fa0/0.50
 desc *** DATA VLAN ***
 encap dot1q 50
 ip addr 192.168.50.1 255.255.255.0

Wouldn't it be best to place it directly under an always up loopback interface?

int loop0
 ip addr 192.168.100.10 255.255.255.0
 h323-gateway voip interface
 h323-gateway voip h323-id gw1.homenet.net

int fa0/0
 no ip addr
 no shut
int fa0/0.10
 desc *** VOICE VLAN ***
 encap dot1q 10
 ip addr 192.168.10.1 255.255.255.0
int  fa0/0.50
 desc *** DATA VLAN ***
 encap dot1q 50
 ip addr 192.168.50.1 255.255.255.0

Any/All advice welcome....

Cheers, Dave

It would probably work fine under the voice sub int but I would stick all of the config under the loopback.

Also you may want to change this:
Int F0/0.50
Encap dot1q 50 NATIVE

Cisco likes to put EVERYTHING under a loopback int!!!!

Thanks pitviper, always good to get another view on things, the books only take you so far.

no prob - here's some config from my notes:

interface loopback0
h323-gateway voip interface
h323-gateway voip bind scraddr 10.1.100.5 [loopback IP]
h323-gateway voip h323-id c2811_BR2
h323-gateway voip id ZONE_02 ipaddr 10.1.254.1 [Gatekeeper zone/IP]

gateway [enable gateway function]
