Parameters
ip-address : IP address to be statically bound. Note that the specified IP address must belong to the
same network segment as that of the current VLAN interface.
client-identifier : Client ID of a static binding, a string of 4 to 160 characters in the format H-H-H…, each
H indicates 4 hex digits except the last H that indicates 2 or 4 hex digits. For example, aabb-cccc-dd is
a valid ID, while aabb-c-dddd and aabb-cc-dddd are both invalid.
mac-address : MAC address to which the IP address is statically bound.
Description
Use the dhcp server static-bind command to statically bind an IP address of the current DHCP
interface address pool to a MAC address. When the client with the MAC address or ID requests an IP
address, the DHCP server will find the IP address from the binding in the interface address pool for the
client.
Use the undo dhcp server static-bind command to cancel an IP-MAC address binding.
