An engineer is troubleshooting an issue where an SNMPv2c NMS cannot poll interface counters on a Cisco router. Which THREE commands can be used to verify the SNMP configuration and connectivity? (Choose THREE.)
⚠ Common exam trap
Cisco often tests the distinction between verification commands (show) and troubleshooting commands (debug), and candidates may incorrectly select 'debug snmp packet' as a verification tool, forgetting that debug commands are resource-intensive and used only after initial verification fails.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
show snmp
The 'show snmp' command displays the overall SNMP agent status, including enabled traps, system contact, and location. This verifies that SNMP is configured and operational on the router, which is essential for an NMS to poll interface counters.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
show snmp
Why this is correct
This command displays SNMP configuration, including community strings, trap receivers, and packet statistics.
- ✓
show snmp mib ifmib ifindex
Why this is correct
This command shows the interface indices (ifIndex) used by SNMP, which is essential for polling specific interfaces.
- ✗
show ip snmp
Why it's wrong here
`show ip snmp` displays global SNMP statistics, such as packets sent, received, and authentication failures, alongside configured community strings. While tempting as a general SNMP command, it fails this scenario because it does not provide the granular detail needed to troubleshoot why an NMS cannot poll *interface counters*. It does not show specific SNMP views, group configurations, or access control lists (ACLs) that dictate MIB object accessibility or might be blocking polling requests for particular data. This command is useful for a high-level overview of SNMP operational status and basic community string verification.
- ✓
show snmp community
Why this is correct
This command displays all configured SNMP community strings and their access rights (read-only or read-write).
- ✗
debug snmp packet
Why it's wrong here
This is a debug command, not a verification command. It can be used for troubleshooting but is not recommended for general verification due to performance impact.
