Command Reference

Release 11.2 GS

show controllers (GRP image)

To display information that is speciﬁc to the hardware, use the show controllers privileged EXEC

command.

ﬁa [register] | pos [number][details] | queues [slot-number] | sca | xbar]

Syntax Description

atm number (Optional) Displays the ATM controllers. Number is

slot-number/ port-number (for example, 4/0). Slot numbers

range from 0 to 11 for the Cisco 12012 and 0 to 7 for the Cisco

12008.

clock (Optional) Displays the clock card conﬁguration.

csar [register] (Optional) Displays the Cisco Cell Segmentation and

Reassembly (CSAR) information. CSAR is the name of the

chip on the card that handles trafﬁc between the GRP and the

switch fabric interface ASICs.

csc-fpga (Optional) Displays the clock and scheduler card register

information in the ﬁeld programmable gate array (FPGA).

dp83800 (Optional) Displays the Ethernet information on the GRP card.

fab-clk (Optional) Display the switch fabric clock register information.

The switch fabric clock FPGA is a chip that monitors the

incoming fabric clock generated by the switch fabric. This clock

is needed by each card connecting to the switch fabric to

properly communicate with it. There are two switch fabric

clocks arriving at each card; only one can be used. The FPGA

monitors both clocks and selects which one to use if only one of

them is running.

ﬁa [register] (Optional) Displays the fabric interface ASIC information and

optionally display the register information.

pos [number][details] (Optional) Displays the POS framer state and optionally

displays all the details for the interface. Number is slot-number/

port-number (for example, 4/0). Slot numbers range from 0 to

11 for the Cisco 12012 and 0 to 7 for the Cisco 12008.

queues [slot-number] (Optional) Displays the SDRAM buffer carve information and

optionally displays the information for a speciﬁc line card. The

SDRAM buffer carve information displayed is suggested carve

information from the GRP card to the line card. Line cards

might change the shown percentages based on SDRAM

available. Slot numbers range from 0 to 11 for the Cisco 12012

and 0 to 7 for the Cisco 12008.

sca (Optional) Displays the SCA register information. The SCA is

an ASIC that arbitrates among the line cards requests to use the

switch fabric.
