VIP Port Adapter Functions
Figure 22 shows some of the slot port adapter and interface ports of a sample Cisco 7505 system. For example, on a FE-TX/4E VIP in slot 3, the address of the first Fast Ethernet port adapter is 3/0/0 (chassis slot 3, port adapter slot 0, and interface port 0—see the section “Selecting Chassis Slot, Port Adapter, and Fast Ethernet Interface Port Numbers” on page 38 for the Fast Ethernet numbering scheme), and the addresses for the Ethernet 10BASE-T interface ports on the second port adapter (which is a 4E) 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 second port adapter slot number is always 1. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter. For example, the four 10BaseT interface ports on a 4E port adapter in the second port adapter slot in chassis slot 3, would have the following addresses: 3/1/0, 3/1/1, 3/1/2, and 3/1/3. (See Figure 31.)

Note VIP configurations using only one 4E port adapter, and a port adapter blank, or two 4E port adapters, are currently not supported.
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].
