DHCP server port-based address allocation
This feature provides port-based address allocation support when using the Dynamic Host Configuration Protocol (DHCP). The DHCP server supports address allocation based on the point of attachment of the client network.
Network devices performing DHCP Snooping can provide additional information about clients by adding options to the DHCP packets.
DHCP Snooping devices can insert information (option 82) about the client's network location into the packet of that request. The device then sends the request to the DHCP server. The DHCP server reads the option 82 information in the packet header and uses it to implement the IP address or another parameter for the client.
Syntax
config system dhcp server
edit <name>
set option82-match {enable | disable}
config option82-pool
edit <name>
set circuit-id <hex>
set remote-id <hex>
set address <ip address>
set description <string>
next
end
next
end
