undo arp detection static-bind [ ip-address ]
View
System view
Default Level
2: System level
Parameters
ip-address : IP address of the static binding.
mac-address : MAC address of the static binding, in the format of H-H-H.
Description
Use the arp detection static-bind command to configure a static IP-to-MAC binding.
Use the undo arp detection static-bind command to remove the configure static binding.
By default, no static IP-to-MAC binding is configured.
With ARP detection based on static IP-to-MAC bindings configured, the device, upon receiving an ARP
packet from an ARP trusted/untrusted port, compares the source IP and MAC addresses of the ARP
packet against the static IP-to-MAC bindings.
z
If an entry with a matching IP address but different MAC address is found, the ARP packet is
considered invalid and discarded.
z
If an entry with both matching IP and MAC addresses is found, the ARP packet is considered valid
and can pass the detection.
z
If no match is found, the ARP packet is considered valid and can pass the detection.
Note that: If no IP address is specified in the undo arp detection static-bind command, all configured
static IP-to-MAC bindings are removed.
