DHCP Relay Commands

page 36-14

OmniSwitch CLI Reference Guide

Sets the maximum number of hops value for the DHCP Relay configuration. This value specifies the 
maximum number of relays a BOOTP/DHCP packet is allowed to traverse until it reaches its server desti-
nation. Limiting the number of hops that can forward a packet prevents packets from looping through the 
network.

ip helper maximum hops hops

The maximum number of relays (1–16).

By default, the maximum hops value is set to four hops.

• If a packet contains a hop count equal to or greater than the hops value, DHCP Relay discards the 

packet.

• The maximum hops value only applies to DHCP Relay and is ignored by other services.

-> ip helper maximum hops 10

Release 6.1; command was introduced.

Adds or deletes one or more DHCP server IP addresses to the DHCP

Sets the forward delay time value. DHCP Relay will not process a client

equal to or greater than the configured value of the forward delay time.

Displays current DHCP Relay configuration information.

Displays DHCP Relay statistics, including the number of client packets 
received and transmitted to the DHCP server and packets dropped due to 
forward delay time and maximum hops violations.
