I am trying to log into a Ciena 3920 that has been reset to factory settings. I amsetting my gateway to 172.16.233.214, setting my subnet to 255.255.254.1, and setting my ip address to 172.16.233.215. I am using a terminal program to log into the switch. I am setting that to log in to the ip address 172.16.233.214 on port 23. Connection type is telnet and emulation is VT100. It does not establish connection. Is there something i am not setting up right?
