The ASIC uses port number, destination MAC address, destination address type, and VLAN ID to perform
parallel CAM lookups. If the packet is forwarded, it is forwarded via the SPI 4.2 bus to the MAC device.
3
For Gigabit Ethernet SPAs, the MAC device forwards the packets to the PHY laser-optic interface, which
transmits the packet.
Displaying the SPA Hardware Type
To verify the SPA hardware type that is installed in your Cisco ASR 1000 Series Routers, you can use the
show platform command.
The following table shows the hardware description that appears in the show interfaces command output for
each Gigabit Ethernet SPA that is supported on the Cisco ASR 1000 Series Routers.

Effective from Cisco IOS XE Release 3.8.0S, support for the Minimal Disruptive Restartfeature is added
to the line cards that use the SPA-2X1GE-V2, SPA-5X1GE-V2, SPA-8X1GE-V2, SPA-10X1GE-V2,
and SPA-1X10GE-L-V2 Gigabit Ethernet SPAs. For more information on the Minimal Disruptive
Restartfeature, see the chapter “Software Upgrade Process” of the Cisco ASR 1000 Series Aggregation
Services Routers Software Configuration Guide.
Note
Example of the show interfaces Command
The following example shows an output of the show interfaces tengigabitethernet command on a Cisco
ASR 1000 Series Routers with a 1-Port 10-Gigabit Ethernet SPA installed in slot 7:
