TABLE 36
Parameter
Definition
512 to 1023 octets
pkts
The total number of packets received that were 512 - 1023 octets long.
This number includes bad packets.
This number does not include framing bits but does include FCS octets.
1024 to 1518
octets pkts
The total number of packets received that were 1024 - 1518 octets long.
This number includes bad packets.
This number does not include framing bits but does include FCS octets.
History (RMON group 2)
All active ports by default will generate two history control data entries per active Brocade Layer 2
Switch port or Layer 3 Switch interface. An active port is defined as one with a link up. If the link goes
down the two entries are automatically deleted.
Two history entries are generated for each device:
• A sampling of statistics every 30 seconds
• A sampling of statistics every 30 minutes
The history data can be accessed and displayed using any of the popular RMON applications
A sample RMON history command and its syntax is shown below.
device(config)#rmon history 1 interface 1 buckets 10 interval 10 owner nyc02
Syntax:
rmon historyentry-number interface
port
buckets
number interval
sampling-interval
owner
text-string
You can modify the sampling interval and the bucket (number of entries saved before overwrite) using
the CLI. In the above example, owner refers to the RMON station that will request the information.
NOTE
To review the control data entry for each port or interface, enter the
show rmon history
command.
Alarm (RMON group 3)
Alarm is designed to monitor configured thresholds for any SNMP integer, time tick, gauge or counter
MIB object. Using the CLI, you can define what MIB objects are monitored, the type of thresholds that
are monitored (falling, rising or both), the value of those thresholds, and the sample type (absolute or
delta).
An alarm event is reported each time that a threshold is exceeded. The alarm entry also indicates the
action (event) to be taken if the threshold be exceeded.
A sample CLI alarm entry and its syntax is shown below.
device(config)#rmon alarm 1 ifInOctets.6 10 delta rising-threshold 100 1 falling
threshold 50 1 owner nyc02
