DMS Troubleshooting
Problem
: The switch lists itself as the only device in Topology View of DMS.
Problem
: In DMS, the Local image shows the IP address of another switch.
Description
: The switch is listed as only device in DMS Topology View in DMS; all devices are listed in DMS device
list. This is usually because the switch's gateway is not configured appropriately.
Resolution
: An IP Route must be configured manually. For example, a switch IP address of 192.168.1.77 should
have the following IP route configured: ip route 0.0.0.0 0.0.0.0 192.168.1.x. Without the IP route configured, you
may be unable to view all devices on the network in DMS.
1. Go to DMS > Management > DMS Mode to check if the controller IP is correct.
2. Verify that the gateway of this switch is correctly configured.
3. Verify that all connected devices are displayed in DMS Topology View.
Problem
: DMS Connectivity diagnostics fails to ICMP reachable device.
Description
: DMS displays a device which is reachable via ICMP ping as failing the connection status in
diagnostics. Cable status displays as
OK
.
Resolution
: Contact Technical Support. See Contact Us below.
Problem
: DMS will discover the device type, name and model of some cameras and hosts but others are
displayed as
Unknown
.
Description
: When a device is detected by DMS, the device’s information (such as type, model name…etc.) can
be recognized via LLDP (e.g., Switch), UPnP (e.g., AP),
(e.g. IP cam), NBNS (e.g. PC) packets if the device
supports these protocols. So if the device display as
Unknown
, that means this device do not issue above
mentioned protocol for DMS to recognize.
Resolution
: You can manually assign and configure the device type and name for the unknown devices. See the
Topology View > Dashboard or the Topology View section.
