Possible Solution Possible Cause Problem
Disable CDP or LLDP then re-enable it
and verify that the team registers the
address. When CDP or LLDP is first enabled,
it may take 30 seconds to receive the
first CDP or LLDP frame. It is
possible that this delay occurred as
the teaming driver attempted to
register the CDP or LLDP multicast
address with the miniport. This delay
may have caused the team to fail to
register the multicast address. CDP or LLDP is enabled and CDP
or LLDP frames are being
transmitted by the network device
but they are not being received by
the team.
Map your network configuration using
Discovery Protocol and verify the
configuration is satisfactory. Some network devices may only
transmit a CDP or LLDP frame down
a single port in a trunk. In that case,
you should expect that the data from
the port that is receiving the frame
should represent all ports in that
aggregation.
If two ports in an aggregation happen
to contain different data (like
different Device IDs) that may alert
you to a network misconfiguration.
When using SLB, 802.3ad, and
Dual-Channel teams some ports in
my aggregation (trunk) do not
have any information displayed.
