Troubleshooting
If the OptiView XG is not operating as expected, refer to this table for possible causes and
solutions.
Table 8. Troubleshooting Guide
Problem
Possible Cause & Solution
Cannot establish a network connection.
The OptiView XG’s MAC addresses have not been added to the
network’s MAC access list.
The OptiView XG fails to get an IP address.
There may be no connectivity to a DHCP server on the link. This
could be caused by a DHCP server that is not responding to
requests, in which case you would want to investigate the health
of the DHCP server.
If the analyzer is connected to a trunk port, ensure that the
selected VLAN has connectivity to an operational DHCP server, or
switch to a different VLAN.
Instructions for switching to a different VLAN:
1.
Select the
Link Status
button. This opens the OptiView
Network Port Settings screen.
2.
In the Active VLAN Configuration section, select a VLAN that
has connectivity to a DHCP server.
3.
Select the
OK
button at the bottom of the screen.
Cannot establish a Wi-Fi connection.
Enable Wi-Fi adapters. See page 20.
Cannot establish a network connection on
network ports A, B, C, or D.
Enable the Network Ports by switching on power to Network
Ports A, B, C, and D. See page 30.
The OptiView XG is not reporting all of the
expected networks, devices, and related
detail.
To ensure successful discovery both on-net and off-net, it is
critical that you configure Discovery. Select the OptiView button
(in the upper left corner of the display), then select the
OptiView
Settings
button. Select the
Discovery
button (at the left side of
the screen).
1. To ensure access to the information (SNMP-MIBs) on the
devices' SNMP agent, configure the SNMP credentials on the
SNMP Configuration
tab.
2. Often the devices' SNMP agents are connected to a different
subnet than the one to which the OptiView is connected. These
SNMP or Management subnets need to be configured on the
Extended Discovery Ranges
tab.
3. To allow the OptiView to discover networks beyond the subnet
to which it is connected, configure the remote subnets for
discovery using the
Extended Discovery Ranges
tab.
