Chapter 1 Overview
Identifying Interface Addresses
Identifying Interface Addresses
The following sections describe the interface address formats for the PA-2FE in supported platforms.
Interface addresses specify the actual physical location of each interface on a router or switch.
Interfaces on a PA-2FE 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-2FE installed in a VIP maintain the same address regardless of whether other interface
processors are installed or removed. However, when you move a VIP to a different slot, the interface
processor slot number changes to reflect the new interface processor 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 7120 Router and Cisco 7140 Router Interface Addresses, page 1-17
• Cisco 7200 Series Routers and Cisco 7200 VXR Routers Interface Addresses, page 1-17
• Cisco uBR7200 Series Routers Interface Addresses, page 1-18
• Cisco 7201 Router Interface Addresses, page 1-18
• Cisco 7301 Router Interface Addresses, page 1-18
• Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses, page 1-18
• Cisco 7401ASR Router Interface Addresses, page 1-18
