NIC Teaming causes link lights on switch to blink

  • 1.  NIC Teaming causes link lights on switch to blink

    Posted Feb 16, 2005 03:02 PM
    I have an HP Netserver E800 server running NT6a.
    I have two NIC configured as a team, using
    HP Pro Set.
    The NICs are configured as Adaptive Load Balancing (ALB).
    The NICs are HP NetServer 10/100TX's.
    AFIAK, a feature of teaming is to periodically check the connection of each NIC to determine if one has failed/lost connection.
    Pro Set has a parameter to set the time between checks - 1,2 or 3 seconds.
    When I enable the team, all of the link lights of my hub blink off for a fraction of a second. This was happening about every second when the Check parameter was set to 1 sec., and happens about every 3 seconds, when the param. is set to 3 seconds. However sometimes it is more frequent.
    Is the blinking of the link lights normal?/caused by the check?/detrimental to LAN connectivity/speed?
    LAN connectivity seems normal.
    Thanks for any replies.

    Hi Fritz,

    this is a normal behaviour.
    You use a hub and so every packet is seen on all ports.
    This special layer2-packet is used for the healthcheck.

    regards
