H3C S9500 Series Routing Switches
Note:
The static-bind ip-address command and the static-bind mac-address command
must be used together to configure a static binding. The new configuration overwrites
the previous one.
II. Configuring a static address binding for a VLAN interface address pool
At present, a VLAN interface DHCP address pool supports multiple MAC-IP address
bindings.
Perform the following configuration in VLAN interface view to configure a static address
binding for a VLAN interface address pool:
Configure a static IP-MAC binding for
the current VLAN interface address pool
Remove a static binding
No static IP-MAC binding is configured in an interface address pool.
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.
III. Configuring dynamic IP address assignment
To assign IP addresses dynamically, that is, IP addresses are leased permanently or
temporarily, you need to configure an address range.
Perform the following configuration in DHCP address pool view to configure an address
range for dynamic IP address assignment:
