NET SNMP Client
To manage the device using SNMP through scripts, Dell Networking OS supports
NetSNMP client. You can run scripts that use SNMP to manage the data center/
devices from within the Dell Networking OS itself. Dell Networking OS provides
Perl and Python interfaces for NetSNMP client and to execute the SNMP operations,
you can also use
tclsh exec command. As a part of Net SNMP client, the following
utility applications are supported:
• snmpwalk
• snmpget
• snmpset
• snmpbulkget
• snmpbulkwalk
• snmpgetnext
Managing Executed Scripts
Manage or control the scripts such as to stop, kill, resume, unscheduled, and clear by
using any one of the following commands.
Protect system resources by scheduling scripts to run when resources are within
configured threshold parameters. System resources include switch CPU, memory,
and file system.
