1.2 Configuring ARP

The ARP table can be maintained dynamically or manually. Usually, the manually
configured mappings are known as static ARP entries. The user can display, add or
delete such entries with commands.
The following sections describe static ARP configuration tasks:

Enabling/Disabling ARP Entry Checking

Configuring the Dynamic ARP Aging Timer

1.2.1 Enabling/Disabling ARP Entry Checking
Perform the following configuration in system view to enable/disable ARP entry
checking:
Enable the ARP entry checking function so that the
switch will not learn any ARP entry containing a
multicast MAC address
Disable the ARP entry checking function so that the
switch can learn ARP entries containing multicast MAC
addresses
By default, the ARP entry checking function is enabled, that is, the switch is disabled
from learning ARP entries for multicast MAC addresses.
1.2.2 Adding/Deleting a Static ARP Entry
Perform the following configuration in system view to add/delete a static ARP mapping
entry.
Add a static ARP entry

By default, the ARP table is empty and ARP entries are obtained through dynamic ARP.
