Switch 3650 how to connect 2 via fiber optic?

[Ralf110666]

Good morning.

I have 2 switches Type 3650 one has 24 ports the second has 48 port. additional each switch has 4 slots for g-bic modules. 2 gigabit and 2 ten gigabit.

I have to establish a connection via fiber optic from switch to switch as tengigabit via port TE1/1/4 on each switch.

A router 2911 is working as dhcp server and dns,  its connected  to one of the "normal" 1gb ports of the first switch. 

On that switch i get ip address and internet access on a connected client. But i don´t get access to the web interface of the switch. Everything is on factroy defaults and initial config is not done. So in my opinion i should get access to the web interface using the default user name and pw, but the web inferface deny access.

Here is the confit of switch no1 ( 24 port)

Hello,

how do you access the web interface ? I don't see an IP address configured on your switch:

interface Vlan1

no ip address
shutdown

[Ralf110666]

i know the ip for the switch supplied by the router, because when i start i follow this sequence.

- Start router

- if its up, start switches ( so the switch gets the first address out of the dhcp address pool. (10.0.130.31)

- connect client PC to the switch ( it gets the second address from the dhcp address pool.(10.0.130.32)

then i have internet connection via switch and router.

then i use the browser on the client computer  input switch address (http://10.0.130.31) and the switch login appears on on the browser... i input the factory defaults (admin/cisco) and get acces deny because of wrong pw and/or user name.

[Georg Pauwen]

Hello,

you have configured local authentication:

ip http authentication local

Unless I missed it, I don't see a local username and password. Try and configure

username admin privilege 15 password cisco

[Dennis Mink]

if you are sayinig your switch gets an IP address through dhcp (you might want to change that and stick a static ip address on).

your ip http server is on. you would need to define a local user name priv 15 password 0 <password>

cos otherwise it cant authenticate

[Ralf110666]

Ok now i had access to the web interface ...but after basic setup and set a new pw for web access, the switch restarted and i wasnt able to get access again... allways wrong password message ...and i am 100% sure that i input the right one wich i gave to the webinterface before. Or do i have to set the same pw via console to the router with user command privilege 15.

Also Factory reset doesnt work. (as described by pressing mode button) If i press mode button ...just the mode changes and noting else there is no blinking...nothing.

Hi,

I am sure that you are facing typo issue with username or password. 

Here is password recovery process:

Thanks for the link. I will try this out tomorrow. I dont think that it is a typo issue because used really simple user name and password, because its just a test setup.

maybe i would not need the web interface to setup the switches basics. i just need both switches communicate via interface TE/4 and deploy dhcp, comming from a dhcp server connected to a lan port of switch no 1. i just thought its maybe more easy with the switch web interface. The switches i used before were not needed to be configured thatswhy i am a bit confused about this ones :)

Best regards

Ralf
