1.6 Troubleshooting
Symptom: The switch cannot ping the host directly-connected to a port.
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 an 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 the 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.
