Configuring a static IPv4 source guard entry

Static IPv4 binding entries take effect only on the ports configured with the IPv4 source guard function

To configure a static IPv4 binding entry on a port:
Step
1. Enter system view.
2. Enter Ethernet interface view.
3. Configure a static IPv4 source
guard entry on the port.
NOTE:
You cannot configure the same static binding entry on one port, but you can configure the same static
•
entry on different ports.
• If a static binding entry to be added denotes the same binding as an existing dynamic binding entry, the
new static binding entry overwrites the dynamic binding entry.

Setting the maximum number of IPv4 source guard entries

The maximum number of IPv4 source guard entries is used to limit the total number of static and dynamic
IPv4 source guard entries on a port. When the number of IPv4 binding entries on a port reaches the
maximum, the port does not allowed new IPv4 binding entries any more.
If the maximum number of IPv4 binding entries to be configured is smaller than the number of existing
IPv4 binding entries on the port, the maximum number can be configured successfully and the existing
entries are not affected. New IPv4 binding entries, however, cannot be added more unless the number
of IPv4 binding entries on the port drops below the configured maximum.
To configure the maximum number of IPv4 binding entries allowed on a port:
