Alarm Table - D-Link DES-6300 User Manual

Modular L3 Ethernet Switch User's Guide
Index – Specifies the History Control Table entry from which the sample was
taken.
Sample Index – Indicates the specific sample the information in the table reflects.
Interval Start – Indicates the time at which the sample was taken. The Interval
start time is represented in an hour, minute, and second format, for example, 5
hours, 26 minutes, and 2 seconds.
Drop Events – Indicates the number of dropped packets due to lack of network
resources during the sampling interval. This may not represent the exact number
dropped packets, but rather the number of times dropped packets were detected.
Octets – Indicates the number of data octets, including bad packets, received on
the network.
Pkts – Indicates the number of packets received during the sampling interval.
Broadcast Packets – Indicates the number of good broadcast packets received
during the sampling interval.
Multicast Packets – Indicates the number of good multicast packets received
during the sampling interval.
CRC Align Errors – Indicates the number of packets received during the
sampling session with a length 64-1,518 octets. However, the packets has a bad
Frame Check Sequence (FCS) with an integral number of octets or a bad FCS with
a non-integral number.
Undersize Packets – Indicates the number of packets received less than 64 octets
long during the sampling session.
Oversize Packets – Indicates the number of packets received more than 1,518
octets long during the sampling session.
Fragments – Indicates the number of packets received less than 64 octets long
and had a FCS during the sampling session.
Jabbers – Indicates the number of packets received more than 1,518 octets long
and had a FCS during the sampling session.
Collisions – Estimates the total number of packet collision that occurred during
the sampling session. Collisions are detected when repeater ports detect two or
more stations transmit simultaneously.
Utilization – Estimates the main physical layer network usage on an interface
during the session sampling. The value is reflected hundreds of percent.

Alarm Table

Displays a list of all alarm entries, created using the Element Statistics or the Port Statistics.
To generate Alarms based on the traffic handled by the device, the alarm is first set in the graph
window.
To set an Alarm:
1. Display the Element Statistics Graph window.
2. In the Alarm Definition area click New. The New Alarm screen opens:
