Packet Broadcast Storm Control

Storm Control enables limiting the amount of Multicast and Broadcast frames accepted and forwarded

by the device. When Layer 2 frames are forwarded, Broadcast and Multicast frames are flooded to all

ports on the relevant VLAN. This occupies bandwidth and loads all nodes connected on all ports.

L2 Multicast Forwarding and Filtering

When a frame arrives on any switch port and its destination address is in an L2 multicast address, it is

forwarded to all relevant ports – that is, ports that are members of the relevant multicast group.

Static Multicast Groups

The user may define multicast groups to be supported, per port. Each such group is defined in the context

of a specific single VLAN.

In general, this feature allows the user to manually achieve what IGMP snooping can do automatically as

a replacement (when it is undesirable to use IGMP snooping) or as a supplement (e.g. to handle hosts

that do not generate IGMP reports correctly).

Environmental Monitoring

Power Supply Status

The system is capable of having two power supplies. If more than one power supply is present, the power

supplies are hot swappable, and the system is able to monitor their status.

Fan Status

The system monitors the status of the fans, if they are present.

Stacking

Stack Management

The stack is controlled and managed from a single unit called the master unit. Any other unit member of

the stack is named stack slave.

The stack master provides:

•

Single point of control and management for every member of the stack, including itself

•

Single interface for the user to control and mange the stack

Stand-alone and Stack-mode Operation

Each unit may work in one of two modes: Stand-alone, or Stack-mode. The operational mode is

determined at Boot time of the software, and can only be changed by a unit reset.

Stack Membership

A stack is comprised of units based on the same types of Packet Processors. A stack can include up to

eight FE devices, or up to eight GE devices.
