Figure 34-12. Administration > Shut Down page
When restarting the ZoneRanger software, the ZoneRanger will stop processing requests during
the restart period which may last several minutes. During that time, the ZoneRanger web
interface will be unavailable.
SNMP
The Administration > SNMP page shows if there are any duplicate SNMPv3 Engine IDs and
provides a mechanism that facilitates the process of updating SNMPv3 passwords.
Figure 34-13. Administration > SNMP page Duplicate Engine IDs tab
The Administration > SNMP page Duplicate Engine IDs tab displays the list of IP addresses
which ZoneRanger has determined to have the same SNMPv3 Engine ID. Each SNMP Agent t
hat supports v3 has a unique Enigne ID associated with that agent. When a ZoneRanger issues
an SNMP v3 proxy request or receives an SNMPv3 notification, the SNMP Engine ID is cached
by IP address. IP addresses on the same device may use the same SNMP Engine ID. When
more than one device has the same SNMP Engine ID, SNMP v3 packets from the device with
the lower SNMP Engine Reboots and SNMP Engine Time will most likely be discarded.
The Refresh button will re-check the cache for duplicate Engine Ids.
