Isolated Group provides protection for certain ports
The isolated group feature allows certain ports to be designated as protected.
All other ports are non-isolated. Traffic between isolated group members are blocked. Traffic
can only be sent from isolated group to non-isolated group.

Mac-based 802.ad LACP with automatic link fail-over
Dynamic fail-over means packets will not get assigned to any trunk member port that has failed.
If one of the ports were to fail, traffic will automatically get distributed
to the remaining active ports.

802.1x Access Control improves network security
802.1x features enable user authentication for each network access attempt. Port security
features allow you to limit the number of MAC addresses per port in order to control the
number of stations for each port. Static MAC addresses can be defined for each port to ensure
only registered machines are allowed to access. By enabling both of these features, you can
establish an access mechanism based on user and machine identities, as well as control the
number of access stations.

802.1d Compatible & 802.1w Rapid Spanning Tree
For mission critical environments with multiple switches supporting STP, you can configure the
switches with a redundant backup bridge path, so transmission and reception of packets can
be guaranteed in event of any failover switch in the network.

2 Dual Media ports for flexible fiber connection
Ports 25,26 dual media ports are provided for flexible fiber connection. You can select to install
optional transceiver modules in these slots for short, medium or long distance fiber backbone
attachment. Use of the GBIC will disable their corresponding
built-in 10/100/1000Base-T connections.

Broadcast/Multicast/unknown-unicast Storm Control
To Limit too many broadcast/multicast/unknown-unicast flooding in the network,
broadcast/multicast storm control is used to restrict excess traffic. Threshold values are
available to control the rate limit for each port. Packets are discarded if the count exceeds the
configured upper threshold.
