Support Tips

Due to maintenance work, there will be a temporary inaccessibility of the LMC on Monday, 16.09.2024 from 18:00 CEST to approx. 18:30 CEST. We expect a maximum downtime of 3 to 5 minutes for individual LMC services during the maintenance period.

The sending of alarm messages will be deactivated during the maintenance.

However, with the exception of the cloud-managed Hotspot and the Dynamic DNS functionality, network operations will not be affected.

For the LTA service, the short downtime appears as follows:

• Existing LTA connections remain functional.
• New connections cannot be established during the downtime unless they have already been connected in the last few days and have activated the "Enable LTA client self-sustaining continued operation" function.
• Configuration changes and rollouts to the gateways are not possible.
• Monitoring information may contain gaps.

We thank you for your understanding.

Currently, the switch models GS-3510XP, GS-3126XP (HW MOD A0) and GS-3528XP (HW MOD A1 and A2) cannot be updated from LCOS SX 4.30 Rel to 4.30 RU1 via the LMC, as the update mechanism in the LMC sends the firmware in a wrong file format to the devices.

Until further notice, LANCOM Systems therefore recommends to upload the firmware update manually via the webinterface of the affected devices or via SCP (only possible with a direct connection to the switch, but not via the WEBconfig tunnel in the LMC). For this purpose, please use the *.upx file in the Download portal.

As an alternative you can also obtain LCOS SX 4.30 RU1 as a custom firmware via the LMC. If necessary, please contact LANCOM support, so that they can provide the custom firmware for your project.

The Content Filter rating servers on LANCOM routers were not available from 19.07.2024 till 21.07.2024 at approximately 6:00 am MEST. The Content Filter was therefore not functional.

The Content Filter in LANCOM R&S®Unified Firewalls was not affected by the disruption, as another OEM partner is used.

Since  01.07.2024 it is not possible to open a Case through e-mail. Cases can be opened via the support portal or by phone.

To create a ticket in the portal, you either need the support PIN or the device serial number registered for LANcare.

After an update to LCOS SX 4.30 Rel operational restrictions can occur on three switch types. Due to this reason, LANCOM Systems has withdrawn this firmware for the affected switch types as a precaution, so that they are not available to download anymore.

The following switch types are affected:

• GS-3510XP
• GS-3126XP (HW MOD A0)
• GS-3528XP (HW MOD A1 and A2)

In an existing installation, that was originally set up with LCOS 10.50 or earlier, even after an update to a current LCOS version the remote site DEFAULT (initially used for VPN dial-in connections, as long as it hasn't been authenticated) is assigned the Diffie-Hellman group DH14 at the most.

When an Advanced VPN Client connection is set up on such a router via LANconfig 10.80 Rel, the Diffie-Hellman group DH15 is stored in the profile file. Thus, the VPN connection cannot be established.

You can find information regarding troubleshooting of this issue in the following Knowledge Base article:

Troubleshooting guide: Cannot establish AVC connection created with LANconfig 10.80 Rel

In LCOS FX 10.11 Rel the service for Content and Anti spam filtering is not started automatically in an HA cluster scenario. After a change to the Slave firewall in the HA cluster, websites cannot be invoked anymore and instead the block site of the URL/Content filter is displayed.

This behavior is fixed in LCOS FX 10.11 RU1. Therefore LANCOM Systems urgently recommends performing an update to this version.

In LANconfig, updating the switch firmware and automatically checking for new firmware versions is not possible.

LANCOM Systems therefore recommends to perform a firmware update via the web interface of the switch or via LMC. In the LMC, the mechanism for automatic firmware updates can also be carried out.
