show fail-safe

Description                                                    Display fail-safe information.

Syntax                                                                  show fail-safe {config | information}

Parameter

Description

config

Displays the fail-safe configuration entered by you or other admins.

information

Displays fail-safe settings and statistics. The output differs between models that use FPGAs in hardware and models that do not. (See “Example” below.)

Mode                                                                   All

Example                                                            The following commands configure some fail-safe settings and verify the changes.

ACOS(config)#fail-safe session-mem-recovery-threshold 30

ACOS(config)#fail-safe fpga-buff-recovery-threshold 2

ACOS(config)#fail-safe sw-error-recovery-timeout 3

ACOS(config)#show fail-safe config

fail-safe hw-error-monitor-enable

fail-safe session-memory-recovery-threshold 30

fail-safe fpga-buff-recovery-threshold 2

fail-safe sw-error-recovery-timeout 3

 

Example                                                            The following command shows fail-safe settings and statistics on an ACOS device that uses FPGAs in hardware:

ACOS(config)#show fail-safe information

Total Session Memory (2M blocks):                  1012

Free Session Memory (2M blocks):                   1010

Session Memory Recovery Threshold (2M blocks):     809

Total Configured FPGA Buffers (# of buffers):      4194304

Free FPGA Buffers in Domain 1 (# of buffers):      507787

Free FPGA Buffers in Domain 2 (# of buffers):      508078

Total Free FPGA Buffers (# of buffers):            1015865

FPGA Buffer Recovery Threshold (# of buffers):     256

Total System Memory (Bytes):                       2020413440

 

The following table describes the fields in the command output.

Field

Description

Total Session Memory

Total amount of the ACOS device’s memory that is allocated for session process­ing.

Free Session Memory

Amount of the ACOS device’s session memory that is free for new sessions.

Session Memory Recovery Threshold

Minimum percentage of session memory that must be free before fail-safe occurs.

Total Configured FPGA Buffers

Total number of configured FPGA buffers the ACOS device has. These buffers are allocated when the ACOS device is booted. This number does not change during system operation.

The FPGA device is logically divided into 2 domains, which each have their own buffers. The next two counters are for these logical FPGA domains.

Free FPGA Buffers in Domain 1

Number of FPGA buffers in Domain 1 that are currently free for new data.

Free FPGA Buffers in Domain 2

Number of FPGA buffers in Domain 2 that are currently free for new data.

Total Free FPGA Buffers

Total number of free FPGA buffers in both FPGA domains.

FPGA Buffer Recovery Threshold

Minimum number of packet buffers that must be free before fail-safe occurs.

Total System Memory

Total size the ACOS device’s system memory.

Example                                                            The following command shows fail-safe settings and statistics on an ACOS device that does not use FPGAs in hardware. (The FPGA buffer is an I/O buffer instead.)

ACOS(config)#show fail-safe information

Total Session Memory (2M blocks):                  1018

Free Session Memory (2M blocks):                   1017

Session Memory Recovery Threshold (2M blocks):     305

Total Configured FPGA Buffers (# of buffers):      2097152

Free FPGA Buffers (# of buffers):                  2008322

FPGA Buffer Recovery Threshold (# of buffers):     1280

Total System Memory (Bytes):                       4205674496
