Indicates
The sample number.
The date and time this log entry was
made.
Percentage of utilization.
Raw number of octets received at the
interface. Provides some indication of
the amount of network bandwidth
being used.
Counts the raw number of readable
Ethernet packets of legal length
received at the interface.
Broadcast packets are a normal part of
network operation. For example, IP
networks use broadcasts as part of
Address Resolution Protocol (ARP) to
resolve network addresses.

The percentage of available bandwidth used
by traffic.
A sharp increase could indicate a need to
reconfigure the network.
A sharp increase could indicate a need to
reconfigure the network. (However, octets
are a better indication of bandwidth
utilization.)
Uses monitoring to recognize oncoming
broadcast storms. Broadcast storms occur
when stations are creating traffic that
generates more traffic.
Possible cause: Broadcasts cause every host
on a network segment to process the packet.
Possible actions:
• To prevent broadcast storms, use
VLANs to limit the area of the
network that each broadcast packet
affects. In general, each VLAN
creates a separate broadcast domain.
More VLANs mean less proliferation
of broadcast packets.
• Monitor the broadcast rate of your
network during normal operation.
• Establish a baseline.
• Use Rate Limiting to reduce
broadcasts.
