Basic Alarm Configuration
3-4 Viewing Alarm Status
The available alarm variables are:
• In Octets Kb (ifInOctets) — tracks the number of octets of data received by the
selected interface. Note that this value has been converted for you from octets
(or bytes) to kilobytes (or units of 1000 bytes); be sure to enter your thresholds
accordingly. For example, to set a rising threshold of 5000 octets, enter a
threshold value of 5; to set a falling threshold of 1000 octets, enter a threshold
value of 1.
• Total Errors (ifInErrors) — tracks the number of error packets received by the
selected interface.
• Broadcast/Multicast (ifInNUcast) — tracks the number of non-unicast — that
is, broadcast or multicast — packets received by the selected interface.
Port Number
Provides a sequential indexing of the interfaces installed in your 7C0x
SmartSwitch chassis. Available interfaces are indexed from left to right in the hub,
and follow physical port indexing on each individual module. (Note that some
Ethernet modules index ports from bottom to top, rather than top to bottom; the
Port # displayed here will reflect that indexing scheme.)
IF Number
Displays the interface number assigned to each available interface. Interface
indexing follows an XXXXYY scheme, where X = slot index times 10,000, and
Y = port index. For example, an interface index of 30017 would be assigned to
port 17 on the module installed in slot 3 of the chassis.
IF Type
Displays each interface’s type: FDDI, Ethernet, or ATM. Note that there is no type
distinction between standard Ethernet and Fast Ethernet.
Status
Displays the current status of the selected alarm type for each interface: Enabled
or Disabled. Remember, this status refers only to the alarm type which is selected
at the top of the window; each of the other two alarm types can have different
states.
Log
Indicates whether or not each alarm has been configured to create a silent log of
event occurrences and the alarms that triggered them: Yes if it has, No if it hasn’t.
TIP
Note that the three pre-selected alarm variables are all MIB II variables; this allows you to
configure alarms for any interface installed in your 7C0x SmartSwitch chassis — even
those for which no specific RMON statistics yet exist.
