Switch Management Concepts

tag its own PVID onto the packet and use this information to make
forwarding decisions. As a result, the packets coming from the non-
compliant device would automatically be placed on the ingress ports
VLAN and could only communicate with other ports that are
members of this VLAN.

Broadcast Management

Broadcast transmissions, packets sent to every devices on the LAN,
are a vital part of any network. However, they can often cause
problems on the network and even network failure. For this reason
the Switch has a number of tools for managing broadcast packets on
your network.

Broadcast Storms

Broadcast storms are a common problem on today’s networks.
Basically, they consist of broadcast packets that flood and/or are
looped on a network causing noticeable performance degradation and
in extreme cases, network failure. Some of the causes of broadcast
storms are network loops, malfunctioning NICs, bad cable
connections, and applications or protocols that generate broadcast
traffic.

Broadcast storms can originate from any number of sources, and
once they are started, they can be self-perpetuating, and can even
multiply the number of broadcast packets on the network over time.
In the best case, network utilization will be high and bandwidth
limited until the hop counts for all broadcast packets have expired,
whereupon the packets will be discarded and the network will return
to normal. In the worst case, they will multiply, eventually using up
all the network bandwidth (although network applications will
usually crash long before this happens), and cause a network
meltdown.
