z
A static ARP entry is effective when the AP works normally. However, when the VLAN or VLAN
interface to which an ARP entry corresponds is deleted, the entry, if permanent, will be deleted,
and if non-permanent and resolved, will become unresolved.
z
The
vlan-id
argument is used to specify the corresponding VLAN of an ARP entry and must be the
ID of an existing VLAN. In addition, the Ethernet interface following the argument must belong to
that VLAN. The VLAN interface of the VLAN must have been created.
z
If both the
vlan-id
and
ip-address
arguments are specified, the IP address of the VLAN interface
corresponding to the
vlan-id
argument must belong to the same network segment as the IP
address specified by the
ip-address
argument.
