Table 623 Configure static address binding for a global DHCP address pool
Operation
Free a statically bound IP address
Configure a MAC address to be statically
bound
Free a statically bound MAC address
IP addresses in a global DHCP address pool are not statically bound by default.
The static-bind ip-address command and the static-bind mac-address
command must be used together as a pair when you configure static binding
entries. When you re-execute the command pair with the same IP address/MAC
address, the newly configured IP address/MAC address overwrites the existing
one.
Configuring static address binding for a VLAN interface address pool
At present, a VLAN interface DHCP address pool supports one-to-multiple MAC-IP
address binding.
Perform the following configuration in VALN interface view.
Table 624 Configure static address binding for a VLAN interface address pool
Operation
Configure static address binding for the
current VLAN interface address pool
Remove a statically bound IP address entry
IP addresses in the address pool of a VLAN interface are not statically bound by
default.
CAUTION: A binding in a VLAN interface address pool cannot be overwritten
directly. If an IP-to-MAC address binding entry is configured and you want to
modify it, you must remove it and redefine a new one.
Configuring dynamic IP address assignment
If you specify to assign IP addresses dynamically, that is, IP addresses are leased
permanently or temporarily, you need to configure an available address range.
Perform the following configuration in DHCP address pool view.
Table 625 Configure an address range for dynamic IP address assignment
Operation
Configure an address range for dynamic IP
address assignment
Remove an dynamic assignment address
range
By default, no IP address range is configured for dynamic IP address assignment.
