The RMON History Group allows you to sample and archive Ethernet statistics for
a specific interface during a specific time interval. History sampling is done per
port.
Note: RMON port statistics must be enabled for the port before an RMON History
Group can monitor the port.
Data is stored in buckets, which store data gathered during discreet sampling
intervals. At each configured interval, the History index takes a sample of the
current Ethernet statistics, and places them into a bucket. History data buckets
reside in dynamic memory. When the switch is re‐booted, the buckets are emptied.
Requested buckets are the number of buckets, or data slots, requested by the user
for each History Group. Granted buckets are the number of buckets granted by the
system, based on the amount of system memory available. The system grants a
maximum of 50 buckets.
You can use an SNMP browser to view History samples.
The type of data that can be sampled must be of an ifIndex object type, as
described in RFC 1213 and RFC 1573. The most common data type for the History
sample is as follows:
1.3.6.1.2.1.2.2.1.1.<x>
The last digit (x) represents the number of the port to monitor.
Perform the following steps to configure RMON History on a port.
RS G8264(config)# interface port 1
RS G8264(config­if)# rmon
RS G8264(config­if)# exit
RS G8264(config)# rmon history 1 interface­oid 1.3.6.1.2.1.2.2.1.1.<x>
RS G8264(config)# rmon history 1 requested­buckets 30
RS G8264(config)# rmon history 1 polling­interval 120
RS G8264(config)# rmon history 1 owner "rmon port 1 history"
where <x> is the number of the port to monitor. For example, the full OID for port
1 would be:
1.3.6.1.2.1.2.2.1.1.1
