Identifying Interface Addresses
Cisco 7200 VXR Routers Interface Addresses
In Cisco 7200VXR series routers, port adapter slots are numbered from the lower left to the upper right,
beginning with port adapter slot 1 and continuing through port adapter slot 4 for the Cisco 7204VXR,
and slot 6 for the 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—if
present.) See
The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number
. See
. For example, if a PA-POS-2OC3 is
installed in slot 1 and the ports are to be two dual independent ports, the interface addresses would be
1/0 and 1/1.
Cisco 7200 VXR Routers with the Port Adapter Jacket Card Interface Addresses
With an NPE-G1 or NPE-G2 installed, port adapter slot 0 of Cisco 7204VXR router or Cisco 7206VXR
router can accept the Port Adapter Jacket Card. When the Port Adapter Jacket Card resides in port
adapter slot 0, the port adapter in the Port Adapter Jacket Card is in port adapter slot 5 on the Cisco 7204
VXR router, or port adapter slot 7 on the Cisco 7206 VXR router. See
The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number
. See
. For example, if a PA-POS-2OC3 is
installed in a Port Adapter Jacket Card in the slot formerly known as slot 0 on a Cisco 7204VXR router,
but now known as slot 5 and the ports are to be two dual independent ports, the interface addresses would
be 5/0 and 5/1(slot 5 and interface port 0 and 1). If a PA-POS-2OC3 is installed in a Port Adapter Jacket
Card in the slot formerly known as slot 0 on a Cisco 7206VXR router, but now known as slot 7, the
interface addresses would be 7/0 and 7/1 (slot 7 and interface port 0 and 1).

1.
Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).
2.
Port adapter slot 0 can accept the Port Adapter Jacket Card if an NPE-G1 or NPE-G2 are installed, but becomes slot 5 on a Cisco 7204VXR router when
a port adapter is installed or slot 7 on a Cisco 7206VXR router when a port adapter is installed.
3.
Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).
4.
Slot 1 is reserved for the supervisor engine. If a redundant supervisor engine is used, it must go in slot 2; otherwise, slot 2 can be used for other modules.
