IEEE 802.1p Priority
The system uses IEEE 802.1p priority to assign priority levels to individual PVCs. The system can
also handle multiple IEEE 802.1p priority queues on a single PVC.
Classifier and Policy
You can create a policy to define actions to be performed on a traffic flow grouped by a classifier
according to specific criteria such as the IP address, port number or protocol type, and so on.
IEEE 802.1x Port-based Authentication
Your MSC supports the IEEE 802.1x standard for centralized user authentication through an
optional network authentication (RADIUS) server.
Spanning Tree Protocol (STP)/ Rapid STP (RSTP)/ Multiple STP (MSTP)
(R)STP detects and breaks network loops and provides backup links between switches, bridges or
routers. It allows a switch to interact with other (R)STP -compliant switches in your network to
ensure that only one path exists between any two stations on the network.
MSTP is backward compatible with (R)STP and allows you to configure multiple spanning trees for
one or more VLANs and still have a loop-free network topology.
Loop Guard
Loop guard protects against network loops on the edge of you network.
MAC (Media Access Control) Filters
Use the MAC filter to filter incoming frames based on MAC (Media Access Control) address(es) or
the OUI (Organizational Unit Identifier) that you specify. You may enable/disable the MAC filter on
specific ports. You may specify up to ten MAC addresses per port.
MAC (Media Access Control) Count Limit
You can limit the number of MAC addresses that may be dynamically learned on a port. You may
enable/disable the MAC count limit on individual ports.
IGMP Count Limit
You can limit the number of IGMP groups a subscriber on a port can join. You may enable/disable
the IGMP count limit on individual ports.
Static Multicast
Use static multicast to allow incoming frames based on multicast MAC address(es) that you specify.
This feature can be used in conjunction with IGMP snooping to allow multicast MAC address(es)
that are not learned by IGMP snooping. You can use static multicast to pass routing protocols, such
as RIP and OSPF.
