Cisco 7600 Series Routers Flexwan Module Interface Addresses - Cisco PA-POS-2OC3 Installation And Configuration Manual

Chapter 1 Overview
Identifying Interface Addresses
The second number identifies the bay (port adapter slot) on the VIP in which the port adapter is installed
(0 or 1). The bays are numbered from left to right on the VIP.
The third number identifies the physical port number (interface port number) on the port adapter. The
port numbers always begin at 0 and are numbered from left to right. The number of additional ports
depends on the number of ports on the port adapter. The PA-POS-2OC3 is a dual-port port adapter,
therefore the port can be 0 or 1.
For example, if a PA-POS-2OC3 is installed in a VIP in interface processor slot 3, port adapter slot 1,
and the ports are to be two dual independent ports, the interface addresses would be 3/1/0 and 3/1/1.
Although the processor slots in the seven-slot Cisco 7507 and the thirteen-slot Cisco 7513 chassis are
Note
vertically oriented and those in the five-slot Cisco 7505 are horizontally oriented, all Cisco 7500 series
routers use the same method for slot and port numbering.

Cisco 7600 Series Routers FlexWAN Module Interface Addresses

In Cisco 7600 series routers, port adapters are installed in a FlexWAN or Enhanced FlexWAN module,
which installs in module slots 2 through 13 (depending on the number of slots in the router). The port
adapter can be installed in either bay (port adapter bay 0 or 1) on the FlexWAN or Enhanced FlexWAN
module. See Figure 1-14, Figure 1-15, Figure 1-16, and Figure 1-17.
The interface address is composed of a three-part number in the format
module-slot-number/port-adapter-bay-number/interface-port-number. See Table 1-3.
The first number identifies the module slot of the chassis in which the FlexWAN module is installed (slot
2 through slot 3, 6, 9, or 13 depending on the number of slots in the chassis). These module slots are
generally numbered from top to bottom, starting with 1. The Cisco 7609 is the exception with slots
numbered right to left, starting with 1.
The second number identifies the bay of the FlexWAN module in which the port adapter is installed
(0 or 1). The bays are numbered from left to right on the FlexWAN module.
The third number identifies the physical port number on the port adapter. The PA-POS-2OC3 is a
dual-port port adapter, therefore the port can be 0 or 1.
For example, if a PA-POS-2OC3 is installed in the FlexWAN module, which is inserted in module slot
3, port adapter bay 0, and the ports are to be two dual independent ports, then the interface addresses of
the port adapter would be 3/0/0 and 3/0/1 (module slot 3, port adapter bay 0, and interfaces 0 and 1).
