i am not sure what you mean by air break speed? can you explain?
What is router ASR9006's MAX CPU and MAX Memory and what should not exceed?
the system has monitoring in place, if the memory reaches low the watchdog process will alert in the syslog.
WDsysmon monitors descriptor utilization (from rls 3.4. onwards) once every minute. Each process is allocated a descriptor limit, the default being 1000 descriptors. Individual applications may modify the limit. Syslog messages will be triggered if a process exceed 80% of the maximum and then again at 85%. At 95% the errant process will be restarted after debug information has been obtained.
