XGS1930 after reboot 52 port (sfp) is down

vvasylenko

After rebooting the XGS1930 switch, the status of the port in which the sfp module is installed is down. Because of this, the switch cannot get an IP address via dhcp from a server connected to another switch, and these two switches are connected via sfp. At the same time, the web interface shows that packets go through sfp and other devices in the network see each other. At the same time, if, for example, an additional static IP address of the web interface is configured, then access to it is only from devices connected directly to the XGS1930, there is no access from devices connected to the second switch. The state of the sfp port is treated only by changing the Speed ​​/ Duplex field in the port settings, by changing the field to any value, for example, 10g and then you can switch back to auto mode. Pulling out and returning the sfp module to the port does not help, only this kind of speed switching described in the proposal earlier. How to fix this bug? SFP modules are used

Hi @vvasylenko,

ZYXEL switch products are recommended to be used exclusively with ZYXEL brand modules to ensure optimal performance and reliability. Using modules from third-party sources can potentially lead to decreased network performance and reliability, such as packet loss and connectivity issues, which also cannot be guaranteed by ZYXEL. ZYXEL may not offer technical support for networking issues that are identified as being caused by IOP with third-party modules.
