ONFIGURATION
A static ARP entry is effective when the device works normally. However, when a
VLAN or VLAN interface to which a static ARP entry corresponds is deleted, the
entry, if permanent, will be deleted, and if non-permanent and resolved, will
become unresolved.
Follow these steps to configure a static ARP entry:
To do...
Enter system view
Configure a permanent static
ARP entry
Configure a non-permanent
static ARP entry
c
CAUTION:
The vlan-id argument must be the ID of an existing VLAN which corresponds to
■
the ARP entries. In addition, the Ethernet interface following the argument
must belong to that VLAN. A VLAN interface must be created for the VLAN.
Before using the command with the vpn-instance keyword to configure a
■
permanent static ARP entry, you need to create a VPN instance and bind it to
the VLAN interface.
Follow these steps to set the maximum number of ARP entries dynamically learned
on an interface:
To do...
Enter system view
Enter interface view
Set the maximum number of
ARP entries dynamically
learned on an interface
After dynamic ARP entries expire, the system will delete them from the ARP
mapping table. You can adjust the aging time for dynamic ARP entries according
to the actual network condition.
Follow these steps to set aging time for dynamic ARP entries:
To do...
Enter system view
Use the command...
system-view
arp static ip-address
mac-address vlan-id
interface-type
interface-number
[ vpn-instance
vpn-instance-name ]
arp static ip-address
mac-address [ vpn-instance
vpn-instance-name ]
Use the command...
system-view
interface interface-type
interface-number
arp max-learning-num
number
Use the command...
system-view
