Cisco 3850 switch

sounds like the switch boot up without loading the saved config.
do a show run. at the bottem there will be a line like this

Configuration register is 0x102

when it's not 0x102 then go to config terminal and give the command

config-register 0x102

then write memory and reload youre switch.

How can I setup the user name and password for the Web GUI from the console???

Are you saving the configuration copy run startup or write memory, if no the configuration will not be saved after reboot.
I recommend for Cisco switch to use the CLI better than the GUI and you can find everything on the network, there is no need for GUI, however if you prefer GUI, check if if you enabled HTTP or HTTP secure on the switch.
Show run | i http
if its enabled you should be able to telnet your switch to port 80 and 443 otherwise you need to open access if you have a firewall in between.

OK I am doing that. The config is still not staying.  I lose the IP each time.  But I'm also trying to enable the web too.  I can get to it I jsut can't login.

put:
show version
and check the configuration register and send it back

OK that finally worked thanks.  But now I'm still having the issue of the config file not saving.  The problem I believe it configuration register is0x142 and it says it will change to 0x102 on the next reload.  But it never does.  I did do a password recovery
Add the following variables.


Switch: SWITCH_IGNORE_STARTUP_CFG=1

Switch: SWITCH_DISABLE_PASSWORD_RECOVERY=0



Then boot the switch.



Switch: boot



Once the switch has booted you can copy the saved config back into the running config.



Switch# copy start run
But I put it back to 0
is there a way to check this?

OK I got it. this is what I had to do:
Switch: SWITCH_IGNORE_STARTUP_CFG=1

Switch: SWITCH_DISABLE_PASSWORD_RECOVERY=0
Switch# no system ignore startupconfig switch all

Switch# system disable password recovery switch all
