SNMP queries available from the SNMP MIB Browser

Use this information to understand the SNMP queries that you can issue using the SNMP MIB Browser.

You can use the SNMP MIB Browser to issue SNMP queries, as described in the following table. The examples shown in the table can all be found within the MIB tree at the following path: iso/org/dod/internet/mgmt/mib-2.

Table 1. SNMP Queries Available from the SNMP MIB Browser
SNMP Query	Description	Node	Example
`Get`	Performs a single instance lookup. It obtains a MIB object together with an instance of this MIB object. For example, if you perform a `Get` query on the `sysDescr` MIB object, then you obtain data for an instance of this single MIB object, `sysDescr.0`.	Single MIB objects only	`sysDescr` `sysUpTime` `sysLocation`
`Get Next` `Walk`	Obtains all instances of a MIB object. This query only works with MIB objects that are sequential. For example, if you issue a `Get Next` query on `ifDescr`, which is a column object in the table `ifTable`, then this query returns the value for all instances of `ifDescr` in the table, that is, `ifDescr.1` and `ifDescr.2`. Note that the `Get Next` and `Walk` queries both perform the same operation.	Single MIB objects	`sysDescr`
		Tables	`ifTable` `ipRouteTable`
		Single MIB objects that represent columns in a table	`ifDescr`
		Branch nodes that contain only single MIB objects	`icmp`
		Branch nodes that contain only tables	`at`
		Branch nodes that contain single MIB objects and tables	`system` `interfaces`
`Get Table`	Obtains a MIB table, which is a grouping of MIB objects. For example, the `interfaces` table contains information for all interfaces on a network device.	Tables	`ifTable` `ipRouteTable`
`Graph`	Displays a real-time graph of a MIB variable for the selected device.	Numerical single MIB objects only	`memory usage`
