MIB Data Collection and Transfer
To configure periodic transfer MIB data from a device to a specified NMS, you group data from multiple
MIBs into list and configure a polling interval. All MIB objects in the list are polled at the specified
interval, and the data is transferred to the specified NMS at a configured transfer interval. The periodic
data collection and transfer mechanism is referred to as the bulk-statistics feature.
To configure bulk statistics, you use a bulk-statistics object list to specify the SNMP object types to be
monitored and a bulk-statistics schema to specify the instances of the objects to be collected. You can
specify MIBs, MIB tables, MIB objects, and object indices by using a series of object identifiers (OIDs).
• A bulk-statistics object list is a user-specified set of MIB objects that share the same MIB index
identified by a user-specified name.
• A bulk-statistics schema is identified by a user-specified name and includes the name of the object
list, the instance to be retrieved for objects in the object list, and the polling interval.
After you configure the data to be collected, a single virtual bulk-statistics file is created with all the
collected data. You can specify how the file is transferred to the NMS (FTP, RCP, or TFTP), how often
the file is transferred (the default is 30 minutes), and a secondary destination if the primary NMS is not
available. The transfer-interval time is also the collection-interval time. After the collection interval
ends, the bulk-statistics file is frozen, and a new local bulk-statistics file is created to store new data. The
frozen file is transferred to the specified destination and then deleted (unless you configure the device
to keep the file in memory for a specified time period). You can configure the switch to send an SNMP
notification to the NMS if a transfer is not successful and to enter a syslog message on the local device.
