Figure 34-75. Diagnostics > Ping/Scan page TCP Port Scan tab
The TCP Port Scan diagnostic can either be used to scan the Well Known Ports (0 - 1023) or a
set of individual ports. The valid Port values are 0 – 65535. The Address does not need to be
a ZoneRanger managed device. After unchecking the Scan Well Known Ports checkbox, a
single TCP port or a TCP port range may be specified.
By default, the TCP Port Scan diagnostic will ping the specified address before scanning TCP
ports. This prevents the scanning of an unreachable device. However, some networks may
filter unreachable messages which causes the scan to stop prematurely. By checking the
Suppress Ping checkbox, the scan will not test for the availability of the device. If the device is
unreachable, there could be a significant timeout for each tested TCP port.
Using the SNMP interface scan diagnostic
The SNMP interface scan diagnostic scans the interface table on the specified address and
displays admin and oper status.
Figure 34-76. Diagnostics > Ping/Scan page SNMP Interface Scan tab
If Use Configured Settings is checked, the configured SNMP rules are used. If Use
Configured Settings is not checked, the SNMP rules for the scan must be specified. A specific
interface index may be entered by unchecking Scan All Interfaces.
SNMP
The Diagnostic > SNMP page provides tools to perform SNMP GetNext requests to perform
the function of the popular snmpwalk command, displaying a tree of information for the
specified device. It also provides a tool to discover SNMPv3 Engine Ids.
