Port Numbering

Certain interface card configurations require the installation or removal of a slot divider in the router’s interface card slot. All slots must be covered by interface cards or blank faceplates for cooling, electromagnetic interference (EMI) reduction, and safety. Procedures for installing interface cards, slot dividers, and blank faceplates are described in “Installing Interface Cards in Cisco 3800 Series Routers” and the Cisco Interface Cards Installation Guide.

AIMS and PVDMs

Advanced integration modules (AIMs) and packet voice data modules (PVDMs) install into connectors on the router motherboard. AIMs provide hardware-based support for additional features. PVDMs are digital signal processor (DSP) SIMMs that provide voice support. The Cisco 3825 router and the Cisco 3845 router can each accommodate two AIMs and four PVDMs.

Installation, replacement, and removal of AIMs and PVDMs require opening the cover of the Cisco 3825 router, or removing the motherboard of the Cisco 3845 router. For more information, see “Installing and Upgrading Internal Components in Cisco 3800 Series Routers.”

Port Numbering

Each built-in network port on a Cisco 3800 series router, and each port or interface on a network module or interface card, is identified in Cisco IOS software by an interface type and a number or series of numbers separated by forward slashes (/). Port numbers for Cisco 3800 series routers follow the rules in this section.

Note Port numbering conventions differ for different router series. For routers that are not part of the Cisco 3800 series, consult your router documentation for port numbering information.

Built-In Ports

Cisco 3800 series routers have two Gigabit Ethernet ports built into the router’s rear panel, labeled 0/0 and 0/1. These numbers are used with the interface-type keyword gigabitethernet to identify the ports in Cisco IOS commands—gigabitethernet 0/0 and gigabitethernet 0/1.

Note If an optional SFP module is installed and selected, it is assigned gigabitethernet 0/0.

Network Module Ports

Ports on network modules inserted into a router slot are numbered slot/port, where slot is the slot number in the router and port is the port number in the network module. For example, port 1 of a Fast Ethernet network module inserted into router slot 2 would be identified as fastethernet 2/1.

The Cisco 3825 router has two slots for network modules. The lower slot is numbered 1 and the upper slot is numbered 2, as labeled on the router’s rear panel. (See Figure 4 on page 3.) The Cisco 3845 router has four slots: 1 at lower right, 2 at lower left, 3 at upper right, and 4 at upper left. (See Figure 8 on page 5.)
