Identifying Interface Addresses
Cisco 7200 Series Routers and Cisco 7200 VXR Routers Interface Addresses
In Cisco 7200 series routers and Cisco 7200 VXR routers, port adapter slots are numbered from the
lower left to the upper right, beginning with slot 1 and continuing through slot 2 for the Cisco 7202,
slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. Port
adapters can be installed in any available port adapter slot from 1 through 6 (depending on the number
of slots in the router). (Slot 0 is reserved for the I/O controller.) See Figure 1-9 and Figure 1-10.
The interface address is composed of a four-part number in the format
port-adapter-slot-number/interface-port-number/t1-line-number: channel-group-number. See
Table 1-3. For example, if a PA-MC-T3 is installed in slot 1of a Cisco 7200 series router, the interface
address would be 1/0/1:0 (port adapter slot 1, interface port 0, T1 line 1, and logical channel group 0).
If a PA-MC-T3 were installed in slot 4, the interface address would be 4/0/1:0.
Cisco uBR7200 Series Routers Interface Addresses
In the Cisco uBR7223 router, only one slot accepts port adapters and it is numbered slot 1.
In the Cisco uBR7246 router and Cisco uBR7246VXR router, port adapters can be installed in two port
adapter slots (slot1 and slot 2). Slot 0 is always reserved for the I/O controller—if present. See
Figure 1-11 and Figure 1-12.
The interface address is composed of a four-part number in the format
port-adapter-slot-number/interface-port-number/t1-line-number: channel-group-number. See
Table 1-3. For example, if a PA-MC-T3 is installed in slot 1of a Cisco uBR7223 router, the interface
address would be 1/0/1/0 (port adapter slot 1 interface port 0, T1 line 1, and channel group 0). If the
PA-MC-T3 were installed in slot 2 of a Cisco uBR7246 router, the interface address would be 2/0/1/0
(port adapter slot 2, interface port 0, T1 line 1 and channel group 0).
Cisco 7201 Router Interface Addresses
In the Cisco 7201 router, only one slot accepts port adapters and it is numbered as slot 1. See
Figure 1-13.
The interface address is composed of a four-part number in the format
port-adapter-slot-number/interface-port-number/t1-line-number:channel-group number. See Table 1-3.
For example, if a PA-MC-T3 is installed in a Cisco 7201 router, the interface address would be 1/0/1/0
(port adapter slot 1 interface port 0, T1 line 1, and channel group 0).
Cisco 7301 Router Interface Addresses
In the Cisco 7301 router, only one slot accepts port adapters and it is numbered as slot 1. See
Figure 1-14.
The interface address is composed of a four-part number in the format
port-adapter-slot-number/interface-port-number/t1-line-number:channel-group number. See Table 1-3.
For example, if a PA-MC-T3 is installed in a Cisco 7301 router, the interface address would be 1/0/1/0
(port adapter slot 1 interface port 0, T1 line 1, and channel group 0).
