Hi @ChristianG, We had an internal meeting regarding this case. The encrypted password for GS1920v2 series admin credentials had already added in Zyxel future roadmap and already listed in the Idea section. Thanks for your advice.

Hi @cuong, Based on the description, I would like to clarify the following to avoid misunderstanding. 1. Based on the topology, does the IPTV traffic path is FTTH > IPTV ISP > LG Media server > TV LG? 2. You mean that after changing the channel, it took the stream 5 seconds to display the image on TV, am I right? For the…

Hi @Jacekr2, Good day. All trunk port must be configured with tagged out to send tagged VLAN to the other devices. To avoid misunderstanding, I would like to confirm that UT = Untagged out, right? If yes, please modify your configuration as follows: 1- Vlan1 1-35 UT, Vlan4 37-48 UT, Trunk 36 (port in Vlan1 Tagged out,…

Hi @cuong, Good day. If there is no ring topology, you just need to enable loop guard to all port to avoid loop in your network environment. About the question below: We suggest configuring DHCP snooping and ARP inspection on layer 2 switch also to prevent some attackers connecting DHCP server which may cause the other…

Hi @Hans, Good day. We'll PM you to request some detailed information that we'll be needing to do the process. Thanks for supporting Zyxel!

Hi @cuong, Based on the description, kindly ensure that the "spanning-tree mode MSTP" on GS1920-48(SW3) is configured. Web GUI: [Advanced Application > Spanning Tree Protocol > Configuration] And configure the interface that you would like to connect the ring with. Eg. SW1 & SW3 interface 1 must be configured with MSTP…

Hi @Filipe_Branco, Welcome to Zyxel Community! Regarding this event, the issue is related to browsers and already fixed by the latest firmware version. Kindly enter this link then download and upload the 2.40 firmware version of GS1900-24HP. Thanks for supporting Zyxel!

Hi @Eric_, Regarding this case, the design for the password is a clear text due to GS1920 series doesn't have a restore configuration button on the panel. Just in case a user forgotten the password, the user still could check the backup configuration file for the password. If the password is encrypted the only way to…

Hi @Damien, Thanks for the information. CNC node detected reboot is determined by polling the system uptime of the node via SNMP. The mechanism is purely simple, CNC keeps on polling the system uptime every 5 minutes and compares the current system uptime and the last 5-minutes system uptime of the node. I'll PM you to…

Hi @Damien, Thanks for the information. The "Node Detected Reboot" mechanism is to check the device system uptime every 5 minutes. It will compare the current polling system uptime and the last 5 minutes system uptime of the device. Please help to verify the following: 1. Help to make a test by connecting a PC in the same…

Hi @Yuri_S, Thanks for the show process status. I'll PM you to retrieve more detail information. Thanks.

Hi @Yuri_S, Thanks for the information. Based on the status more like a link flapping, please help to verify if there is CRC error on port 9. Steps: 1. Access GS1900-24E via webUI. 2. In this page, check if there is counter on "etherStatsCCAlignErrors". If yes, the issue is related o layer 1 (physical issue), try to change…

Hi @MatC_AVA6, Welcome to Zyxel Community! To achieve the goal, please refer to this link on how to configure MAC + 802.1x authentication. But according to your topology, there will be some circumstances if the computer is connected to IP phones. The IP phone will be allocated to guest VLAN only due to IP phone doesn't…

Hi @Yuri_S, Welcome to Zyxel Community! Based on your description, I assume that there is a loop in your network environment. Please help to verify if the "Loop Guard" feature is enabled, because if the feature is disable. In the monitor page for loop guard will not display if there is a loop occur in the environment.…

Hi @Razvan, Thanks for the screenshot.I assume the topology as below: Internet (router) ----- [Port27] GS1900-48 [Port28] ----- PC For the PC connected to port 28, kindly change to "Untagged" because most of the PC doesn't recognize tagged frame VLAN. And for the router, you've mentioned that when you connect the PC to the…
