View
VLAN interface view
Parameter
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 VLAN interface.
client-identifier: Client ID to be statically bound, in the format of H-H-H. It contains 3 to
160 hexadecimal numbers.
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 address pool to a MAC address.
Use the undo dhcp server static-bind command to cancel an IP-MAC address
binding.
By default, no IP address in an address pool is statically bound.
It should be noted that:
An IP address can be statically bound to only one MAC address or one client ID.
A MAC address or client ID can be bound with only one IP address statically.
The IP address to be statically bound cannot be an interface IP address of the
device; otherwise the static binding does not take effect. The bound MAC address
can also obtain another IP address.
Example
# Enter system view.
<Quidway> system-view
System View: return to User View with Ctrl+Z.
# Statically bind the client ID aaaa-bbbb to the IP address 10.1.1.1 (Assume that the
interface address pool of VLAN interface 1 already exists and the IP address belongs
to the address pool).
[Quidway] interface vlan-interface 1
[Quidway-Vlan-interface1]
client-identifier aaaa-bbbb
# Statically bind the IP address 10.1.1.1 to the MAC address 0000-e03f-0305.
(Assume that the interface address pool of VLAN interface 1 already exists and the IP
address belongs to the address pool.)
[Quidway] interface vlan-interface 1
[Quidway-Vlan-interface1]
