LABEL DESCRIPTION
ARP Freeze
ARP Freeze allows you to automatically create static bindings from the current ARP entries (either dynamically
learned or static ARP entries) until the Switch’s binding table is full.
Note: The ARP learning mode should be set to ARP-Request in the NETWORKING > ARP Setup > ARP
Learning screen before you use the ARP Freeze feature.
Condition All – Select this and click ARP Freeze to have the Switch automatically add all the current ARP
entries to the static bindings table.
Port List – Select this and enter the number of the ports (separated by a comma).
You can enter multiple ports separated by (no space) comma (,) or hyphen (-) for a range.
For example, enter “3-5” for ports 3, 4, and 5. Enter “3,5,7” for ports 3, 5, and 7.
ARP entries learned on the specified ports are added to the static bindings table after you
click ARP Freeze.
VLAN List – Select this and enter the ID number of the VLANs (separated by a comma). ARP
entries for the specified VLANs are added to the static bindings table after you click ARP
Freeze.
