Command History

Version Description

9.9(0.0) Introduced on the FN IOM.

8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.

Usage Information This command disables the incrementing of the hops eld when boot requests are relayed to a DHCP server

through the Dell Networking OS. If the incoming boot request already has a non-zero hops eld, the message is

relayed with the same value for hops. However, the message is discarded if the hops eld exceeds 16, to comply

with the relay agent behavior specied in RFC 1542.
