Identifying Interface Addresses

Identifying Interface Addresses

This section describes how to identify interface addresses for the PA-POS-1OC3 in supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on a port adapter 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 port adapter 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 Interface ports are numbered from left to right starting with 0.

The following subsections describe the interface address formats for the supported platforms:

•Cisco 7200 VXR Routers Interface Addresses, page 1-21

•Cisco 7201 Router Interface Addresses, page 1-21

•Cisco 7301 Router Interface Addresses, page 1-21

•Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses, page 1-22

•Cisco 7401ASR Router Interface Addresses, page 1-22

•Cisco 7500 Series Routers VIP Interface Addresses, page 1-22

•Cisco 7600 Series Routers FlexWAN Module Interface Addresses, page 1-23 Table 1-3summarizes the interface address formats for the supported platforms.
