QuestionQ254

Infrastructure Services

While investigating connectivity problems to a router, the following details are observed:

  • Standard pings to every router interface, including loopbacks, succeed.
  • Data traffic is unaffected.
  • SNMP connectivity is intermittent.
  • SSH is slow or disconnects frequently.

Which command must be configured first to troubleshoot this problem?

  • A show policy-map control-plane
  • B show policy-map
  • C show interface | inc drop
  • D show ip route
Explanation

SNMP and SSH traffic destined to the device is processed by the control plane, whereas unaffected data traffic is forwarded in the data plane. A control-plane policing policy can therefore cause intermittent or slow management access without disrupting forwarded traffic. show policy-map control-plane displays the control-plane service policy and its rate and drop counters, allowing control-plane policing to be verified.
