Configure Basic Functions of Port Isolation

The port isolation function realizes unidirectional packet isolation. Assuming that port B is configured as the isolated port of port A, then if a packet whose target port is port B enters port A, the port is directly discarded. However, if a packet whose target port is port B enters port B, the port is normally forwarded. The isolated port can be a port or an aggregation group.

Port isolation is configured based on the isolation group.

• The ports in one isolation group are isolated from each other.

The ports in the isolation group can be configured as ingress, egress, both mode, and the resolutions are as follows:

Table 2-2 Configuration mode forwarding table

• The ports in the isolation group communicate with the ports not added to the isolation group normally.

The ports of different isolation groups can communicate normally.

Configuration Condition

The isolation group is already created.

  When adding one port to the isolation group, the isolation group needs to be created.
