System monitoring for Packet Processors
On FSX devices, errors typically detected in packet processors include:
• Parity errors
• Error Checking Code (ECC) errors
• ConfigTable0 errors
• TCAM error
• TCAM action parity errors
• Token bucket priority parity errors
• State variable parity errors
• Link list RAM ECC errors
• FBUF RAM ECC errors
• Egress VLAN parity errors
• Ingress VLAN parity errors
• Layer 2 port isolation parity errors
• Layer 3 port isolation parity errors
• VIDX parity errors
Besides the error count, sysmon also checks for connectivity of SFM/XBAR links. This happens at the
interval defined by the sysmon-timer command generally or specifically for cross bar.
Use the following commands to configure and display the statistics of cross bar or switch fabric
module:
• sysmon pp error-count on page 310
• show sysmon logs on page 312
• show sysmon counters on page 313
• show sysmon config on page 317
sysmon pp error-count
Configures the sysmon monitoring parameters for error events in packet processors. The no form of
this command resets the parameters to default values.
Syntax
sysmon pp error-count { threshold eventspolling-interval | log-backoff value | action { none |
syslog } }
no sysmon pp error-count
Parameters
threshold
Defines the failure threshold for the fabric adapter error-count event. The threshold is
defined as N/W, where N is the number of events, and W is the number of consecutive
polling periods. When the threshold is reached, actions configured for this event type will
take place. Note that a threshold of 1/W implies that there is no threshold, and no event will
be triggered.
log-backoff
If an error condition persists, it will be continuously logged (internally and/or externally). The
log back-off count skips configured number of logs before logging again. This avoids
overflow of the internal log or of the syslog.
