Configuring Cisco 10000 Series Router PXF Stall Monitor
• PSM cannot detect a LC that gets stalled before interfaces come up on the LC.
• PSM cannot detect stalls in LCs where multiple link bundling is done across LCs.
• PSM state in the active PRE is not synchronized with the standby PRE, even in SSO mode.
Therefore, during a switchover from active PRE to standby PRE, there is a delay in detecting a stall
that occurred during the switchover.
• Management ports available on the PRE is not monitored by PSM.

DETAILED STEPS
Command or Action Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal

Step 3
hw-module pxf stall-monitoring
Example:
Router(config)# hw-module pxf stall-monitoring
Enables PSM on the Cisco 10000 series router. By default,
the threshold values of LC and HTDP reset are set to 3. The
default threshold values for LC and HTDP can be changed
using the hw-module pxf stall-monitoring
command
again.
Step 4
hw-module pxf stall-monitoring [HT-Reset <4-6>
| LC-Reset <4-6>]
Example:
Router(config)# hw-module pxf stall-monitoring
HT-Reset 4
Configures the threshold value for LC and HTDP reset
before the secondary action, PRE switchover, takes place
using the following parameters:
• HT-Reset 4-6—Specifies the threshold value for HTDP
reset. You can configure the value ranging from 4 to 6.
• LC-Reset 4-6—Specifies the threshold value for LC
reset. You can configure the value ranging from 4 to 6.
