Disabling the hop count in DHCP requests

For more information, see Hop count in DHCP requests.

To disable the default behavior of a DHCP relay agent so that the hop count in a DHCP client request is not increased by one at each hop when it is forwarded to a DHCP server, enter the no dhcp-relay hop-count-increment command at the global configuration level:

HP Switch(config)# no dhcp-relay hop-count-increment

To reset the default function, which increases the hop count in each DHCP request forwarded to a DHCP server, enter the following command:

HP Switch(config)# dhcp-relay hop-count-increment

Operating notes

By default, the DHCP relay agent increases the hop count in each DHCP request by one. You must enter the no dhcp-relay hop-count-increment command to disable this function.
You enter the no dhcp-relay hop-count-increment command at the global configuration level. The command is applied to all interfaces on the routing switch that are configured to forward DHCP requests.
This DHCP relay enhancement applies only to DHCP requests forwarded to a DHCP server. The server does not change the hop count included in the DHCP response sent to DHCP clients.
When you disable or re-enable the DHCP hop count function, no other behavior of the relay agent is affected.
You can configure the DHCP relay hop count function only from the CLI; you cannot configure this software feature from the drop-down menus.
A new MIB variable, hpDhcpRelayHopCount, is introduced to support SNMP management of the hop count increment by the DHCP relay agent in a switch.
