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