DES-3526:admin#
create address_binding permit_ip_pool
Purpose To create the entry of permit IP pool.
Syntax
create address_binding permit_ip_pool start_ip <ipaddr>
end_ip <ipaddr> ports [<portlist>|all]
Description This command is used to create an entry for the permit IP pool.
When the switch receives the ARP or IP packet, it will check the
permit IP pool and IP-MAC-Port Binding databases together. When
the IP address of a received packet is one of the by-permit IP, the
packet will be directly permitted without any further checking by the
binding database. Note that, the permit IP pool only affects the ARP
check. It does not affect the ACL filtering for the IP packet.
The start_ip and end_ip field identify a pool. There are maximum 10
entries.
Parameters
start_IP - The start IP address of the entry in permit IP pool.
end_IP - The start IP address of the entry in permit IP pool.
ports - Configure the portlist to apply.
Restrictions Only Administrator and Operator-level users can issue this
command.
