Usage guidelines
This probe mechanism keeps legal dynamic ARP entries valid and avoids unnecessary ARP
resolution during later traffic forwarding. This probe feature sends ARP requests for the IP address in
a dynamic ARP entry.
•
If the device receives an ARP reply before the entry aging timer expires, the device resets the
aging timer.
•
If the device does not receive any ARP reply after the maximum number of probes is made, the
device deletes the entry when the entry aging timer expires.
You can set the maximum number of probes in system view and in interface view. The probe count
set in interface view takes precedence over the probe count set in system view.
Examples
# Allow the device to perform a maximum of five probes for dynamic ARP entries.
<Sysname> system-view
[Sysname] arp timer aging probe-count 5
# Allow the device to perform a maximum of five probes for dynamic ARP entries on VLAN-interface
2.
<Sysname> system-view
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] arp timer aging probe-count 5
