This command displays information about the ARP cache. The first line shows
the cache timeout. It also shows each cache entry, including the IP address,
MAC address, type (static, dynamic, other), and VLAN interface. Note that entry
type “other” indicates local addresses for this router.
◆
Static entries are only displayed for VLANs that are up. In other words, static
entries are only displayed when configured for the IP subnet of a existing VLAN,
and that VLAN is linked up.
