Static Lacp Aggregation Group - H3C S3100-52P Operation Manual

Operation Manual – Link Aggregation
H3C S3100-52P Ethernet Switch
The system sets the ports unable to aggregate with the master port (due to some
hardware limit, for example, cross-board aggregation unavailability) to unselected
state.
The system sets the ports with port attribute configuration (rate, duplex mode, and
link type) different from that of the master port to unselected state.
III. Requirements on ports for manual aggregation
Generally, there is no limit on the rate and duplex mode of the ports (also including
initially DOWN port) you want to add to a manual aggregation group. After aggregation,
the smallest-numbered selected port is the master port of the aggregation group and
the other selected ports are the member ports of the aggregation group.
Note:
For an aggregation group:
When the rate or duplex mode of a port in the aggregation group changes, packet
loss may occur on this port;
When the rate of a port decreases, if the port belongs to a manual or static LACP
aggregation group, the port will be switched to the unselected state; if the port
belongs to a dynamic LACP aggregation group, deaggregation will occur on the
port.

1.1.5 Static LACP Aggregation Group

I. Introduction to static LACP aggregation
A static LACP aggregation group is also manually created. All its member ports are
manually added and can be manually removed (it inhibits the system from
automatically adding/removing ports to/from it). Each static aggregation group must
contain at least one port. When a static aggregation group contains only one port, you
cannot remove the port unless you remove the whole aggregation group.
LACP is enabled on the member ports of static aggregation groups. When you remove
a static aggregation group, the system will remain the member ports of the group in
LACP-enabled state and re-aggregate the ports to form one or more dynamic LACP
aggregation groups. You must not disable LACP on static aggregation ports.
