The result of showing LACP is as follows:
The results of implementing the following command on the two
switches are similar. The result of switch B is omitted. The result
of switch A is showed as follows:
zte(cfg)#show lacp
Lacp is enabled.
Lacp priority is 32768

The above displaying result proves that link aggregation is suc-
cessful. If it is not successful, the result is showed as follows when
the command of show lacp aggregator 3 is implemented.
zte(cfg)#show lacp aggregator 3
%
Group 3 is not active!
Generally, the problem of physical link causes the result. Please
check physical link status.
STP Configuration
STP Overview
Spanning Tree Protocol (STP) is applicable to a loop network. It
blocks some redundant paths with certain algorithms so that the
loop network is pruned into a tree network without any loop, thus
avoiding the hyperplasia and infinite loop of packets in the loop
network.
Rapid Spanning Tree Protocol (RSTP) is on the basis of common
STP, added with the mechanism that the port state can be rapidly
changed from Blocking to Forwarding, which increases the topol-
ogy convergence speed.
Multiple Spanning Tree Protocol (MSTP) is on the basis of RSTP and
STP, added with the forwarding processing of frames with VLAN
ID. The whole network topology structure can be planned into a
Common and Internal Spanning Tree (CIST), which is divided into
Common Spanning Tree (CST) and Internal Spanning Tree (IST),
as shown in
Figure
Many devices enabling MSTP construct MST area in switching net-
work. When the devices satisfy the following conditions, they can
be considered to exist in a MST area. A switching network can
