5.
Set the maximum number of
dynamic ARP entries for the
interface.
arp max-learning-num
number
If the value of the
number
argument is set
to 0, the interface is disabled from
learning dynamic ARP entries.
Setting the aging timer for dynamic ARP entries
Each dynamic ARP entry in the ARP table has a limited lifetime, called an aging timer. The aging timer
of a dynamic ARP entry is reset each time the dynamic ARP entry is updated. A dynamic ARP entry that
is not updated before its aging timer expires is deleted from the ARP table.
To set the aging timer for dynamic ARP entries:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Set the aging timer for dynamic ARP
entries.
arp timer aging
aging-time
By default, the aging time for
dynamic ARP entries is 20 minutes.
Enabling dynamic ARP entry check
The dynamic ARP entry check function controls whether the device supports dynamic ARP entries
containing multicast MAC addresses.
When dynamic ARP entry check is enabled, the device cannot learn dynamic ARP entries containing
multicast MAC addresses, and you cannot manually add static ARP entries containing multicast MAC
addresses.
When dynamic ARP entry check is disabled, the device can learn dynamic ARP entries containing
multicast MAC addresses obtained from the ARP packets sourced from a unicast MAC address. You can
also manually add static ARP entries containing multicast MAC addresses.
To enable dynamic ARP entry check:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enable dynamic ARP entry check.
arp check enable
By default, dynamic ARP entry check is
enabled.
Enabling ARP log output
This function enables a device to output ARP logs generated in ARP resolution.
