Conditions

when input ?show flow monitor PRTG_IPV4_MONITOR cache filter interface input te0/0/2 routing source as 4-octet 4609 format table? will crash even the device don't have any traffic show flow monitor with filter routing soruce/destinaiton as 4-octet or other filelds that didn't be collected will lead to the crash it impacts all xe router platform.

Workaround

None at this time Don't show flow monitor with filter routing soruce/destinaiton as 4-octet or other filelds that didn't be collected
