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.
If an entry with a matching IP address but different MAC address is found, the ARP packet is
considered invalid and discarded.
If an entry with both matching IP and MAC addresses is found, the ARP packet is considered valid
and can pass the detection.
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.
