QuestionQ38

Analyze and Optimize Network Performance

An alert reporting RX errors on eth2 on a node is raised in the cluster. The administrator logs in to the relevant CVM, examines the ping_* files in the data/logs/syststats folder, and observes intermittent ping loss. The affected node has the following network configuration:

Which action should be taken to troubleshoot this issue without disrupting the VMs running on this node?

  • A Replace the cable from eth2 to the switch
  • B Remove eth3 from br0-up and monitor for new alerts
  • C Check the port on the switch side for any errors
  • D Enable balance-s1b on br0-up and monitor if a problem persists
Explanation

eth2 is an uplink in the br0-up active-backup bond. Inspecting the corresponding switch port for error counters, link events, or configuration issues investigates a likely source of RX errors and packet loss without changing the node’s active network configuration or interrupting VM traffic.
