Link Aggregation Problems
You changed the partnerID of an aggregation and all the member
ports that you added have disappeared.
Ports will only become members of an aggregation that has a matching
partnerID. If the partnerID of an existing aggregation is changed
manually, the original member ports will leave. If the partnerID of an
aggregation needs to be configured manually, it should be configured
before any member ports are added. This will ensure that ports gain
the correct partnerID when they are subsequently added to the
aggregation.
Note that LACP enabled ports determine their partnerID automatically
via the LACP protocol.
How do you make automatic aggregations more resilient to
network failures?
Unplanned changes in network topology can result in the unexpected
creation of automatic aggregations. For example, if a Stack splits due to
failure of its cascade, LACP will view the Stack as two separate
partnerIDs and automatically create a second aggregation. To guarantee
the new aggregation has a matching configuration (for example, VLAN
membership etc) to the original aggregation, 3Com recommends that
all member ports are assigned the same configuration before they join
the original aggregation.
You have an aggregation with a mix of manual and automatic
member ports and some ports are inactive.
If you mix manual and automatic member ports in the same
aggregation, the aggregation will not always work correctly. Some ports
may become 'inactive' if the Switch is connected to a device that
dynamically varies the aggregation parameters that are exchanged by
LACP. 3Com therefore recommends that aggregations should not be
configured with a mix of automatic and manual member ports.
