Chapter 1 Overview
Identifying Interface Addresses
Cisco 7010 routers have three slots for port adapters, and two slots for Route Switch Processors (RSPs).
The slots are numbered from bottom to top. You can place the port adapter in any of the VIP interface
slots (slot 0 through 2). Slots 3 and 4 are always reserved for RSPs. The Cisco 7010 router is not shown.
Cisco 7505 routers have four slots for port adapters, and one slot for an RSP. The slots are numbered
from bottom to top. You can place the port adapter in any of the VIP interface slots (slot 0 through 3).
One slot is always reserved for the RSP. The Cisco 7505 router is not shown.
Cisco 7507 routers have five slots for port adapters, and two slots for RSPs. The slots are numbered from
left to right. You can place the port adapter in any of the VIP interface slots (slot 0, 1, 4, 5, or 6). Slots
2 and 3 are always reserved for RSPs. The Cisco 7507 router is not shown.
Cisco 7513 routers have eleven slots for port adapters, and two slots for RSPs. The slots are numbered
from left to right. You can place the port adapter in any of the VIP interface slots (slots 0 through 5, or
slots 9 through 12). Slots 6 and 7 are always reserved for RSPs. The Cisco 7513 router is not shown.
Identifying Interface Addresses
This section describes how to identify interface addresses for the PA-MC-T3 in supported platforms.
Interface addresses specify the actual physical location of each interface on a router or switch.
Note that PA-MC-T3 interface addresses always end with t1-line-number:channel-group-number where:
• t1-line-number identifies the T1 line number on the PA-MC-T3 and is a number from 1 through 28.
• channel-group-number identifies the logical channel group on the T1 line and is a number from 0
through 23.
Interfaces on a PA-MC-T3 installed in a router maintain the same address regardless of whether other
port adapters are installed or removed. However, when you move a port adapter to a different slot, the
first number in the interface address changes to reflect the new port adapter slot number.
Interfaces on a PA-MC-T3 installed in a VIP or FlexWAN module maintain the same address regardless
of whether other interface processors or modules are installed or removed. However, when you move a
VIP or FlexWAN module to a different slot, the interface processor or module slot number changes to
reflect the new interface processor or module slot.
Note The Cisco IOS software recognizes a configured logical channel group as a serial interface; therefore,
you can use all configuration commands that are available for serial interfaces with configured logical
channel groups. You can configure a logical channel group to carry data traffic using the following
encapsulation methods: PPP, HDLC, SMDS, and Frame Relay. Set the encapsulation method you want
using the serial interface configuration commands. For configured logical channel groups, you can use
all command switches that apply to a serial interface (including optimum switching).
Note Interface ports are numbered from left to right starting with 0.
