11 Troubleshooting ARP
The OmniSwitch supports Address Resolution Protocol (ARP). In order to troubleshoot issues related to
ARP, a basic understanding of the protocol is required. Some basic concepts are covered in the sections
below.
Reading the IETF RFC 826 specification is highly recommended to anyone implementing or troubleshoot-
ing an ARP issue on their network. Reading “Configuring IP” in the appropriate OmniSwitch Network
Configuration Guide is also highly recommended.
