Configuring the Access Gateways
This section describes the commands that are used to configure the following Catalyst 6500 series access
gateway modules:
• Analog station gateway—24-port FXS analog interface module
• Digital trunk gateway—8-port T1/E1 PSTN interface module
Configuring a Port Voice Interface
If DHCP is enabled for a port, the port obtains all other configuration information from the TFTP server.
When disabling DHCP on a port, you must specify some mandatory parameters as follows:
• If you do not specify the DNS parameters, the software uses the system DNS configuration on the
supervisor engine to configure the port.
• 8-port T1/E1 PSTN interface module only: You cannot specify more than one port at a time because
a unique IP address must be set for each port.
To configure a port voice interface for the DHCP, TFTP, and DNS servers, perform this task in privileged
mode:
Task Command
Configure a port voice interface for the DHCP,
TFTP, and DNS servers.
set port voice interface mod/port dhcp enable
[vlan vlan]
set port voice interface mod/port dhcp disable
{ipaddrspec} {tftp ipaddr} [vlan vlan]
[gateway ipaddr] [dns [ipaddr] [domain_name]]
