VLAN interface view 

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. 

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.
