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 and
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
” 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.
