QuestionQ13

Layer 3 Technologies

An engineer receives a ticket regarding a router that has reloaded. Monitoring-system graphs show different traffic patterns between logical and physical interfaces after the router reboots. Which action resolves the issue?

  • A Configure the snmp ifindex persist command on the physical interfaces.
  • B Clear the logical interfaces with snmp ifindex clear command.
  • C Trigger a new snmpwalk from the monitoring system to synchronize interface OIDs.
  • D Configure the snmp ifindex persist command globally.
Explanation

SNMP ifIndex persistence retains IF-MIB interface index values across reloads, maintaining consistent interface identification and preventing monitoring graphs from associating traffic with changed interface OIDs. Global configuration applies this persistence to all applicable interfaces.
