Identifying Chassis Slot, Port Adapter Slot, and HSSI Interface Port Numbers
Note For the Cisco 7206 and Cisco 7206VXR router shelves, the PA-H in port adapter slot 2 would
have the address x/2/0, where x is the number assigned to the router shelf during the initial
configuration of the Cisco AS5800 Universal Access Server.
VIP2 Ports
In VIP2s in Cisco 7000 series and Cisco 7500 series routers, physical port addresses specify the
actual physical location of each interface port on the router interface processor end. This address is
composed of a three-part number in the format interface processor slot/port-adapter/interface port,
as follows:
• The first number identifies the interface processor slot in which the VIP2 is installed.
• The second number identifies the physical port adapter slot on the VIP2, and is either 0 or 1.
• The third number identifies the interface port on the HSSI port adapter, which is always
numbered as interface 0 for PA-H.
Note Although the processor slots in the 7-slot Cisco 7000 and Cisco 7507 and 13-slot Cisco 7513
are vertically oriented and those in the 5-slot Cisco 7010 and Cisco 7505 are horizontally oriented,
all models use the same method for slot and port numbering.
Interface ports on the VIP2 maintain the same address regardless of whether other interface
processors are installed or removed. However, when you move a VIP2 to a different slot, the first
number in the address changes to reflect the new interface processor slot number.
On the VIP2, the first port adapter slot number is always 0. The second port adapter slot number is
always 1. The individual interface port numbers are always 0.
You can also identify interface ports by physically checking the slot/port-adapter/interface port
location on the back of the router or by using show commands to display information about a specific
interface or all interfaces in the router.
Catalyst RSM/VIP2 Ports
In the Catalyst RSM/VIP2, the address is composed of a two-part number in the format
port-adapter/interface port, as follows:
• The first number identifies the physical port adapter slot on the Catalyst RSM/VIP2, and is either
0 or 1.
• The second number identifies the interface port on the HSSI port adapter, which is always
numbered as interface 0 for PA-H.
Interface ports on the Catalyst RSM/VIP2 maintain the same address regardless of whether other
interface processors are installed or removed.
On the Catalyst RSM/VIP2, the first port adapter slot number is always 0. The second port adapter
slot number is always 1. The individual interface port numbers are always 0.
You can also identify interface ports by physically checking the port-adapter/interface port location
or by using show commands to display information about a specific interface.
