Table 123 IP Source Guard > IPv4 Source Guard Setup > Static Binding
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 IP Application >
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 port(s) (separated by a comma).
In stacking mode, the first number represents the slot and the second the port
number. Enter 1/ 1-1/24,2/28 for ports 1 to 24 for the Switch in slot 1 and port 28 for
the Switch in slot 2, for example.
ARP entries learned on the specified port(s) are added to the static bindings table
after you click ARP Freeze.
VLAN List - Select this and enter the ID number of the VLAN(s) (separated by a
comma). ARP entries for the specified VLAN(s) are added to the static bindings table
after you click ARP Freeze.
Static Binding
MAC Address Enter the source MAC address in the binding.
IP Address Enter the IP address assigned to the MAC address in the binding.
VLAN Enter the source VLAN ID in the binding.
Port Specify the port(s) in the binding. If this binding has one port, select the first radio
button and enter the port number in the field to the right. In stacking mode, the first
field is the slot ID and the second field is the port number. If this binding applies to
all ports, select Any.
Add Click this to create a new entry or to update an existing one.
This saves your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation
panel to save your changes to the non-volatile memory when you are done
configuring.
Cancel Click this to reset the values above based on the last selected static binding or, if not
applicable, to clear the fields above.
