1 Configuring ISR NET-SNMP

The ISR uses the NET-SNMP suite, which includes libraries and tools for using the SNMP protocol, on Oracle Linux for monitoring purposes. Oracle Linux does not include the NET-SNMP suite by default, so to enable monitoring, you must obtain the NET-SNMP package, enable the package upon startup, and configure firewalld on each ISR host to listen to UDP on port 161 for SNMP.

Note:

The NET-SNMP suite is an established toolkit with extensive documentation and information resources.
