Chapter 3 Configuring the AGM for the First Time
Using the Cisco IOS CLI
Understanding the Interface Numbering
The AGM has three slots in which you can install interface cards:
• Slot 1 supports voice interface cards (VICs), WAN interface cards (WICs), and voice and WAN
interface cards (VWICs).
• Slot 2 supports voice interface cards (VICs), WAN interface cards (WICs), and voice and WAN
interface cards (VWICs).
• Slot 3 supports only VICs and VWICs (no WICs).
• Slot 4 is reserved for the 8-port RJ21 FXS module.
Each individual interface is identified by a slot number and a port number. The slots are numbered as
follows:
• Slot 0 supports the following main board embedded interfaces:
–
Console port (con 0)
–
Ethernet Management port (Fast Ethernet 0/0)
–
Gigabit Ethernet backplane connection (Gigabit Ethernet 0/0:S)
• Slot 1 ports are numbered from right to left (1/1 and 1/0)
Note On the WIC-2A/S, the top slot is 0 and the bottom slot is 1.
• Slot 2 ports are numbered from right to left (2/1 and 2/0)
• Slot 3 ports are numbered from right to left (3/0 and 3/1)
• Slot 4 ports (on the 8-Port FXS module) are sequentially numbered from right to left, starting with
0 for the right-most port. As the 8-port FXS module is located in slot 4, the eight ports are numbered
4/0 to 4/7.
When you configure an interface, identify the interface name before the slot and port numbers. For
example, if you install a serial T1 VWIC interface in slot 2, port 0 would be labeled as serial 2/0.
The Gigabit Ethernet port interface name, slot, and port number are gigabit-ethernet 0/0:S. The S
represents the possible subinterfaces, which could be one of six VLAN connections.

Using the Cisco IOS CLI
Cisco voice gateways run versions of the Cisco IOS software that includes specialized adaptations for
Voice over IP (VoIP) and Media Gateway Control Protocol (MGCP). If you are familiar with other
versions of Cisco IOS, you will find configuring Cisco voice gateways straightforward because you will
use the Cisco IOS CLI, with which you are familiar.
