Cisco Catalyst 4000 Access Gateway Module Installation and Configuration Note
OL-3008-01
Chapter 1 Overview
Hardware Features
Figure 1-3 shows the front-panel of the AGM. You can see the console port on the lower left and the Fast
Ethernet port immediately to the right of the console port.
Figure 1-3 Access Gateway Module Fast Ethernet and Console Ports
The AGM ports are named according to their positions in their respective slots. From the left, the slots
are numbered 1, 2, 3, and 4. Slots 1 and 2 are for VWICs, slot 3 is for VICs, and slot 4 is for multiflex
modules.
A VWIC, VIC, or WIC can have one or more ports, so ports on the interface modules are sequentially
numbered starting with 0 for the right-most port and increasing by one in the right to left direction.
Note The inverse port-numbering order is inherited from existing VWIC, VIC, and WIC port-numbering
conventions.
Hardware Features
The AGM supports the following hardware features:
• A DSP bank with 24 DSPs (4 SIMMs with 6 DSPs each) supporting a maximum of 96 voice
channels.
• Two voice or WAN interface module (VWIC) slots—Support VWICs, voice interface modules
(VICs), and WAN interface modules (WICs).
• One VIC slot—Supports the same VWICs and VICs as slots 1 and 2, but does not support WICs.
• One multiflex slot—Reserved for the 8-Port and 16-Port RJ21 FXS modules.
• One Fast Ethernet port—Reserved for management purposes only. It does not support data
switching or routing.
• One console port—For configuration purposes, you can connect via terminal or modem.
• One Gigabit Ethernet backbone interface—Standard IOS Gigabit Ethernet interface with the
following exceptions:
–
Supports 802.1q instead of ISL
–
Cannot be shut down without losing communication with the Supervisor Engine
• Encryption Service Adapter (ESA)—High-performance data encryption module to offload some of
the encryption processing from the AGM main processor and to improve performance.
