1.5 Troubleshooting IP Address Configuration

Symptom: The switch cannot ping through the directly connected host.
Solution: You can perform troubleshooting as follows:
Check the configuration of the switch, and then use the display arp command to
check whether the host has a corresponding ARP entry in the ARP table
maintained by the Switch.
Check the VLAN that includes the switch port connecting the host. Check whether
the VLAN has been configured with a VLAN interface. Then check whether the IP
addresses of the VLAN interface and the host are on the same network segment.
If the configuration is correct, enable ARP debugging on the switch, and check
whether the switch can correctly send and receive ARP packets. If it can only send
but cannot receive ARP packets, errors may occur at the Ethernet physical layer.
