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.
Execute the display hardware internal module interface-name interface-number status
command in probe view to collect the status information.
Execute the display hardware internal module interface-name interface-number reg 1
command in probe view to collect the FPGA information.
Execute the display hardware internal module interface-name interface-number reg 2
command in probe view to collect the MAC information.
Execute the display hardware internal module interface-name interface-number reg 3
command in probe view to collect the PHY information.
For interfaces on a FIP-300 or FIP-310 LPU, execute the display hardware internal nae slot
slot-number freein command in probe view to collect the hardware buffer information.
For interfaces on a FIP-240 or SAP-4EXP LPU, execute the display hardware internal dpaa slot
slot-number bman pool-info command in probe view to collect the hardware buffer information.
