5.5.2 Port Trunk

The load balance modes of port aggregation include:
1. . Source MAC Address Mode: load balance calculation of packet-based source MAC address;
2. . Destination MAC Address Mode:load balance calculation of packet-based destination MAC address;
3. .Source and Destination MAC Address Mode: load balance calculation after XOR of packet source MAC
address and destination MAC address;
4. . Source and Destination IP Mode: load balance calculation after XOR of packet source IP address and
destination IP address.
The designation of balance calculation is based on overall situation, the default mode is " Source and Destination
IP Mode". No modification needed except special requirement.
There is pull-down list in the port aggregation page, there are two aggregation groups in the list, each group
supports maximum 4 ports. If the user configure more than 4 ports for a group, there will be a error prompt box
displayed as below picture.

5.5.3 Port Isolation

One of the routine method to isolate L2 Messages is associating different ports to different VLANs and the
isolation between VLANs works, which cause the waste of VLAN resources.With the port isolation function,
messages of different ports can be isolated even in the same VLAN.
Users only need to put the ports to the isolation list, and the ports will be isolated.The port isolation function
enables safer and more flexible network solutions.
As shown in below picture, Port 1-4 can only communicate with Port 5 and they are isolated from Port 6-24,SFP1
and SFP2. Port 1-4 are isolated from each other.
