Parameters

hex-string&<1-255>: A character string, which is used to match against Option 60 (vendor class identifier option). hex-string is a hexadecimal number ranging from 0 to FF. &<1-255> indicates that you can type up to 255 hexadecimal numbers, which are separated by spaces.

ip range min-address max-address: Specifies the IP address range for dynamic allocation. min-address is the lowest IP address and max-address is the highest IP address for dynamic allocation.

Description

Use vendor-class-identifier to specify an IP address range for the DHCP clients of a specific vendor.

Use undo vendor-class-identifier to restore the default.

By default, no IP address range is specified for the DHCP clients of any vendor.

After this feature is configured in an extended DHCP address pool, the DHCP server, when using the extended DHCP address pool to assign an IP address to a DHCP client, checks whether Option 60 in the DHCP request is the same as the character string configured with the vendor-class-identifier command. If yes, the DHCP server selects an IP address from the address range specified with this command. If not, the DHCP server selects one from the address range specified with the network ip range command.

	NOTE: Only extended address pools support this command. The IP address range specified with this command must be included in that specified with the network ip range command.

Related commands: network ip range and network mask.
