DHCP Relay Commands
page 32-12 OmniSwitch 6250 CLI Reference Guide November 2009
ip helper maximum hops
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
Syntax Definitions
hops The maximum number of relays (1–16).
Defaults
By default, the maximum hops value is set to four hops.
Platforms Supported
OmniSwitch 6250
Usage Guidelines
•
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.
Examples
-> ip helper maximum hops 1
-> ip helper maximum hops 10

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

show ip helper stats Displays DHCP Relay statistics, including the number of client packets
received and transmitted to the DHCP server and packets dropped due to
