 CAUTION: 
•
  To prevent traffic interruption, enable link-a
ggregation traffic redirection on devices at both ends of the
aggregate link. 
•   To prevent packet loss that might occur at a reboot, disable both MSTP and link-aggregation traffic 
redirection.

Ethernet link aggregation configuration examples 
In an aggregation group, only ports that have the sa
me port attributes and class-two configurations (see 
 Configuration classes ) a
 s the reference port (see  Reference port) can ope rate as Selected ports. 
Make sure that all member ports have the same po rt attributes and class-two configurations as the 
reference port. The other settings only need to be configured on the aggregate interface, not on the 
member ports.

Layer 2 static aggregation configuration example 
Network requirements 
As shown in Figure 12: 
•   D
evice A and Device B are connected through their respective Layer 2 Ethernet interfaces 
GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3.  
•   Configure a Layer 2 static aggregation group on both Device A and Device B. Enable VLAN 10 at 
one end of the aggregate link to communicate with VLAN 10 at the other end, and VLAN 20 at one 
end to communicate with VLAN 20 at the other end.  
•   Enable traffic to be load-shared across aggregat ion group member ports based on the source and 
destination MAC addresses.

Configuring port isolation 
Port isolation enables isolating Layer 2 traffic for data privacy and security without using VLANs. You can 
also use this feature to isolate the hosts in a VLAN from one another. 
To use the feature, assign ports to a port isolation group. Ports in an isolation group are called isolated 
ports. One isolated port cannot forward Layer 2 traf fic to any other isolated port on the same switch, 
even if they are in the same VLAN. An isolated port  can communicate with any port outside the isolation 
group if they are in the same VLAN.  
The switch series supports only one isolation group isolation group 1. The isolation group is 
automatically created and cannot be deleted. Ther e is no limit on the number of member ports. 
Assigning a port to the isolation group
