i've configured my new cisco switch 9200
i've put the fibre port in trunk mode, allow all vlans, etc.
in the 3750x i can ping it and from all 2960s/x i can ping it to
however when i try to ssh or use the webgui it says "connection time out" and nothing happen and "connection timeout" in putty
cant seem to find whats missing
What about the default gateway? From your test the PC and switch management SVI are in the same Layer2 broadcast domain and communication will work without a default gateway configured. If a device which resides in a different subnet cannot reach the 3750 but can reach the other 2960's then it is most likely down to the face the 3750 does not know where to route packets destined to other subnets to.
Can you please supply a detailed answer for your resolution. I have a network of both 2960x and 9200 switches connected to a 9300 core. Everything configured the same, the 2960x's can be SSH'd into but the 9200's cannot. I can reach any device connected to them without issue, but not the switches themselves.
