delete address_binding
Purpose Used to delete IP–MAC-Port Binding entries.
Syntax
delete address_binding [ip_mac [ipaddress <ipaddr> {mac_address <macaddr>} |
all] | blocked [all | vlan_name <vlan_name> mac_address <macaddr>]]
Description This command is used to delete IP–MAC-Port Binding entries. Two different kinds of
information can be deleted.
• ip_mac – Individual Address Binding entries can be deleted by entering the MAC
and IP addresses of the device. Toggling to all will delete all the Address Binding
entries.
• blocked – Blocked address binding entries (bindings between VLAN names and
MAC addresses) can be deleted by entering the VLAN name and the MAC
address of the device. To delete all the Blocked Address Binding entries, toggle
all.
Parameters <ipaddr> – The IP address of the device where the IP–MAC-Port Binding is made.
<macaddr> – The MAC address of the device where the IP–MAC-Port Binding is made.
<vlan_name> – The VLAN name of the VLAN that is bound to a MAC address in order to
block a specific device on a known VLAN.
all – For IP-MAC-Port Binding all specifies all the IP–MAC-Port Binding entries; for
Blocked Address Binding entries all specifies all the blocked VLANs and their bound
physical addresses.
Restrictions Only Administrator and Operator-level users can issue this command.
