Usage
Information
This command disables the incrementing of the hops field when boot requests are relayed to a DHCP
server through FTOS. If the incoming boot request already has a non-zero hops field, the message will
be relayed with the same value for hops. However, the message will be discarded if the hops field
exceeds 16, to comply with the relay agent behavior specified in RFC 1542.
