Common Error Conditions
If the ARP is not getting resolved in either of the two workstations, then the following conditions may
exist:
•
General health of the switch or NI.
•
Physical link status might not be operational
•
MAC address not learned on the port
•
ARP request not reaching the switch, which may be possible because:
- The workstation is not sending an ARP request
- The workstation is not able to understand the ARP request
- ARP packet might have got corrupted
- Duplicate IP addresses configured on the workstations in the same VLAN
