In order to monitor a firewall, router, or switch, CloudTest must be able to establish an SNMP connection to the device. If you are not sure how to enable this, consult your hardware vendor's documentation.

If a firewall prevents SNMP access, see the topic Monitoring a Server Behind a Firewall.

In addition, the device must support the system and interfaces MIB object trees ( iso.org.dod.internet.mgmt.mib-2.system and iso.org.dod.internet.mgmt.mib-2.interfaces , respectively).
