Configuring the 12E/2FE Interfaces 6-3

Identifying Port Adapter Slot and Interface Port Numbers

For example, the addresses of the interface ports on the 12E/2FE port adapter in chassis slot 3 and

slot 4 are 3/0 through 3/13 (chassis slot 3 and interface ports 0 through 13). If the 12E/2FE port

adapter was in port adapter slot 5 and slot 6, these same interface ports would be numbered 5/0. For

example, the addresses of the interface ports on the 12E/2FE port adapter in port adapter slot 1 and

slot 2 are 1/0 through 1/13 (chassis slot 1 and interface ports 0 through 13).

Figure 6-1 12E/2FE Interface Port Number Example (Cisco 7206 Shown)

Note For the Cisco 7206 router shelf, the address of the 12E/2FE interfaces in chassis slot 3 and

slot 4 would be x/3/0 through x/3/13, where x is the number assigned to the router shelf during the

initial conﬁguration of the Cisco AS5800 Universal Access Server.

Figure 6-2 shows the interface ports of a 12E/2FE port adapter in slot 1 and slot 2 of a

Cisco uBR7246. The port adapter slots are numbered slot 1 and slot 2 (slot 0 is always reserved for

the optional Fast Ethernet port on the I/O controller—if present). The individual interface port

numbers always begin with 0. The number of additional ports depends on the number of ports on a

port adapter. Port adapters can occupy any port adapter slot; there are no restrictions.

For example, the address of the interface ports on the 12E/2FE port adapter in chassis slot 1 and

slot 2 are 3/0 through 3/13 (chassis slot 3 and interface ports 0 through 13).
