Operating System-Independent Configuration

The following sections describe the NAM configurations that are independent of the switch operating

system.

Use the autostart command to specify that some collections should be automatically configured on

every available data source (including all known VLANs) whenever the NAM is initialized. These

collections may also be configured explicitly through SNMP by a management station on some data

sources. Collections that are explicitly configured through SNMP take precedence over “autostart”

collections, so if both are configured, only the explicitly configured collections are started on each data

source when the NAM initializes.

If you enter the command that instructs the NAM to automatically start a collection, you must reboot the

NAM for that command to take effect.

The NAM allows the following collection types to be started automatically:

•addressMap—addressMapTable from RMON2-MIB (RFC 2021)

If the NMS never sets the addressMapMaxDesiredEntries scalar, then the NAM uses the value -1

(for no limit).

•art—artControlTable from draft-warth-rmon2-artmib-01.txt

•etherStat—etherStatsTable from RMON-MIB (RFC 1757)

•prioStats—smonPrioStatsControlTable from SMON-MIB (RFC 2613)

•vlanStats—smonVlanStatsControlTable from SMON-MIB (RFC 2613)

For example, each dataSource (interface or VLAN) is configured with an etherStatsEntry (from

RMON-1) after you enter the autostart etherstats enable command and reboot the NAM. The

etherStatsOwner field is set to the value monitor.

The automatic start process is performed after setting up any collections that were explicitly created

through SNMP by a management station, and stored in the NVRAM in the NAM. Automatic start

collections are not configured on data sources that already have a collection of that type configured

through SNMP.

Enable the etherStat collection type by entering this command from the root account of the NAM:

root@localhost# autostart etherstat enable

Enable the addressMap collection type by entering this command from the root account of the NAM:

root@localhost# autostart addressmap enable

Enable the prioStats collection type by entering this command from the root account of the NAM:

root@localhost# autostart priostats enable
