This trap-only integer, ranging from 1 to 4,000,000, reports the connection count for a load-balance group member. The description explains a connection is typically identified by the five-tuple of source and destination IP, source and destination port, and protocol, so this value gives an admin a load snapshot for that member at the time of the trap. A trap showing hwConnectionNum near the 4,000,000 ceiling would alert an admin that a member is approaching its connection capacity and may need traffic redistributed to other pool members.
