Cisco ASR 1000 Series Aggregaion Services Routers Hardware Installation and Initial Configuration Guide
OL-13208-03
Chapter 1 Cisco ASR 1000 Series Routers Hardware Overview
Functional Overview
The SPA bays are bay 1, bay 2, and bay 3. The built-in 4xGE SPA ports are located in the SPA 0 location
and will be addressed as GE
0/0/x. The Cisco ASR 1002 Router provides a built-in 4-Gigabit Ethernet
interface and this SPA is physically located on the Cisco embedded ASR1000-RP1 board. The Cisco
ASR 1000 Series ESP card is located in slot 1 and labeled as FP0.

MAC Address Information
The Media Access Control (MAC) or hardware address is a standardized data link layer address that is
required for certain network interface types. These addresses are specific and unique to each port and
are not used by other devices in the network. The Cisco ASR 1000 Series Routers assign and control the
MAC addresses of its shared port adapters.
You can identify shared port adapter slots by using software commands. To display information about:
• All shared port adapter slots, use the show interfaces command.
• A specific shared port adapter slot, use the show interfaces command with the shared port adapter
type and slot number in the format show
interfaces port-adapter-type slot-number/port-number.
Note If you abbreviate the command (sh int) and do not specify shared port adapter type and slot number (or
arguments), the system interprets the command as show interfaces and displays the status of all shared
port adapters and ports.
The MAC addresses are assigned to the slots in sequence. For example, in the Cisco ASR 1006 Router,
the first address is assigned to slot 0 and the last address is assigned to slot 6. The actual MAC address
assignment is 16 MAC addresses per SPA slot for half-height SPAs and 64 per SPA slot for full-height
SPAs. Also, the Cisco ASR 1000 Series RP1 RP Management Ethernet port is assigned one MAC
address from the end of the pool and for a Cisco ASR 1006 Router with two Cisco ASR 1000 RP1s, each
ASR10000 RP1 is assigned one MAC address.
Using this address scheme, you can remove shared port adapters and insert them into other routers
without causing the MAC addresses to move around the network or be assigned to multiple devices.
