RARP table
The Reverse Address Resolution Protocol (RARP) provides a simple mechanism for
directly-attached IP hosts to boot over the network. RARP allows an IP host that does not have a
means of storing its IP address across power cycles or software reloads to query a directly-attached
router for an IP address.
RARP is enabled by default. However, there must be a static RARP entry for each host that will use
the Layer 3 Switch for booting. The following table contains the object that define each RARP entry.
They are available in all devices, except ServerIron products.
