Troubleshooting the Issue: Intermittent SNMP Connectivity and Slow SSH | Cisco Exam 300-410-ENARSI
Question
While troubleshooting connectivity issues to a router, these details are noticed: -> Standard pings to all router interfaces, including loopbacks, are successful.
-> Data traffic is unaffected.
-> SNMP connectivity is intermittent.
-> SSH is either slow or disconnects frequently.
Which command must be configured first to troubleshoot this issue?

The given scenario indicates that there are some connectivity issues with the router. The standard pings to all the router interfaces are successful, but there are problems with SNMP and SSH connections. Also, data traffic seems to be unaffected.
To troubleshoot this issue, we need to gather more information about the router's configuration and its current state. Based on the given options, the best command to start with is "show policy-map control-plane."
A policy-map is a set of rules that define how traffic should be processed by the router. The control-plane policy-map is responsible for handling traffic that is destined for the router itself, including management protocols like SSH and SNMP.
By using the "show policy-map control-plane" command, we can get an overview of how the router is processing traffic for these management protocols. We can check if there are any rate-limiting or policing rules that are affecting the traffic flow, and whether the router is dropping any packets.
If the policy-map output shows that the router is dropping packets for SSH or SNMP traffic, we can further investigate the issue using the "show interface | inc drop" command. This command will show us if there are any interfaces that are experiencing drops or errors, which could be causing the connectivity issues.
Finally, if we find that the router is not properly routing traffic for SSH or SNMP, we can check the routing table using the "show ip route" command to see if there are any missing or incorrect routes.
In summary, the best command to start troubleshooting this issue is "show policy-map control-plane," as it will provide an overview of how the router is processing traffic for management protocols like SSH and SNMP.
