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.
