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.

00e0-fc01-0000, and the outbound interface being Ethernet 1/0/1 of VLAN 10.
