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.

A new MIB variable, hpDhcpRelayHopCount, is introduced to support SNMP management of the hop count increment by the DHCP relay agent in a switch.
