Arp Timer Aging - H3C S5120-SI Series Command Reference Manual

Note that:
A static ARP entry is effective when the device 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.
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.
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-addres argument.

Examples
# Configure a static ARP entry, with the IP address being 202.38.10.2, the MAC address being
00e0-fc01-0000, and the outbound interface being GigabitEthernet 1/0/1 of VLAN 10.
