VIP Port Adapter Functions
Interface ports on the 4T port adapter 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 first number in the address changes to reflect the new slot number.
Figure 32 shows some of the slot port adapter and interface ports of a sample Cisco 7505 system. For example, on a VIP-4R/4T VIP in slot 3, the addresses of the 4T port adapter are 3/1/0 through 3/1/3 (chassis slot 3, port adapter slot 1, and interface ports 0 through 3). The first port adapter slot number is always 0. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter.

Note Current VIP configurations support only one 4R port adapter and one 4T port adapter on a VIP motherboard. Single and dual 4T configurations are not available.
You can identify interface ports by physically checking the slot/port adapter/interface port location on the back of the router or by using software commands to display information about a specific interface or all interfaces in the router.
To display information about a specific interface, use the show interfaces command with the interface type and port address in the format show interfaces [type slot/port adapter/port].
