Parameters
hex-string&<1-255>: A character string, used to match against Option 60 (vendor class identifier option).
The hex-string argument 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. The
min-address argument is the lowest IP address and the max-address argument is the highest IP address
for dynamic allocation.
Usage guidelines
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.
• 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.
Examples
# Specify IP address rang 10.1.1.1 to 10.1.1.5 for the DHCP clients of vender a0 b0 0c.
