I have two Switches A and B. Currently, the fibre is connected to only Switch A which is live.
Say now i bring in a new Switch B. I try to trunk the fastethernet to Switch A and it works. I am able to access internet through Switch B.
1) However, i cannot telnet to Switch B. I have already configure a telnet password. What could went wrong?
2) I tried to telnet to Switch A but i could not type in the username and password.
The moment i type in, it will display:
"Username: Connection closed by foreign host."
Why it will affect Switch A connection?
3)Lastly, i choose to connect from fastethernet interface to the other fasterthernet interface. Both are 3560 series switches.
Is it because i did not use a GigaStack module to connect to each other or fasterthernet interface is not allowed to connected to another fasterthernet interface?
