Hi, if one switch fails, the surviving ones should keep configuration.

When available, you should always use stack, like in the 3750 that gives you a 32 Gbps connection and makes the switch appears like a single one.

Hi,


I stack the two switches, e.g. switch A and switch B. They stack to each other and treat it as single big switch.


If the switch A (or switch B) is down, can I access the switch?


If yes, how about the config?

e.g.

I config switch A with Vlan 2, 3, 5 and 7 for first 24 ports.

I config switch B with Vlan 3, 7, 10, 15 for the next 24 ports.


Do they keep itself config?.
