Troubleshooting ports

Failure to ping the directly connected device

Symptom

An Ethernet interface cannot ping the directly connected device.

Solution

To resolve the problem:
1. Execute the display interface command and perform the following tasks:
Verify that the interface is up.

Verify that the speed and duplex mode of the local end match the speed and duplex mode of

the peer end.
Verify that the cable and interface are operating correctly by viewing the packet statistics of

the interface.
Verify that the transceiver module of the local end matches the transceiver module of the

peer end if the interface is a fiber port.
2. Use the display arp all command to verify that the interface has learned the ARP entry of the
directly connected interface. If not, use the debugging arp packet command to verify that the
interface can send and receive ARP packets correctly.
3. Use the debugging ip packet command to verify that the interface can send and receive IP
packets correctly.
4. Use the debugging ip icmp command to verify that the interface can send and receive ICMP
packets correctly.
5. If the problem persists, collect the following information for the interface:
Execute the display hardware internal module interface-name interface-number

statistics command in probe view to collect the interface statistics.
