Recently, I am having an issue with 3 new routers out of 10, which looks weird , the issue is that the i cant see the router through the LAN console port, when i power cycle the router, i can access the LAN port for for an hour or less, and then goes offline…
the lan port is being used for internal network/untagged vlan…
i have done the same scenario for almost 260 device, i never had any issue…
