Symptom Tip
Receive load balancing fails to begin
functioning.
Check the Group Properties to verify that the dedicated IP
address has been entered. If no address appears in the
Group Properties dialog box, enter one to enable receive
load balancing.
Receive load balancing stops
functioning.
Cables may be disconnected, or there may be other
hardware problems. Reconnect or change the cables.
Correct any other hardware problems. Bidirectional load
balancing is restored after this type of failure when
applications create new connections or new clients log in.
Reconnecting cables does not restore
load balancing.
Check the event log for a duplicate IP address. If another
device is using a load balancing group's dedicated IP
address, change one of the IP addresses. See “Changing an
IP Address” on page 48 for instructions.
Receive load balancing does not
function across a router.
Receive load balancing across a router is not supported.
Clients across the router cannot use receive load balancing,
but clients within the subnet get higher throughput from
receive load balancing.
