Hello,I have a 3930 swtich,but i can't use the command to manage the swtich,I konw I should use the console wire to connect the PC,but how can i enter the interface of the console,please tell me the baud rate or the IP address of the 3930 swtich.Thanks so much!
You can use MGMT port to configure the SW.
connect Laptop to MGMT port, Assign IP on your laptop 172.16.233.215/16
Then, Use putty, Your target ip ( SW IP) 172.16.233.214/16.
Thanks for your patience, I have tried the ways, but unfortunately I still cannot enter the switch.I had connected the PC to MGMT port, then set the IP address as you provided, but the interface of PC showed a bit of garbage characters. I ues my PC to ping 172.16.233.214(my PC IP address had been setted 172.16.233.215),it shows request time out.
As Kazi Tanvir Ahamed mentioned above, you can Telnet to the switch when connected to the MGMT port over IP 172.16.233.214.
Alternatively, if you have a console cable, you can connect to the switch over the Console port using a Serial connection. The settings for the serial connection are as follows:
Thanks so much,your patience will be appreciated ,but unfortunately, I had tried these ways, I can't enter the swtich,I had connect PC to MGMT port , then set the IP address as you provided, but the interface of PC showed a bit of garbage characters.I ues my PC to ping 172.16.233.214(my PC IP address had been set 172.16.233.215),it shows request time out.
I have a console cable,and do those settings :
The result shows I can enter the swtich,but no what matter I input,the swtich shows nothing.
Can you provide a screenshot of your ipconfig/ifconfig when trying to connect to the switch over the management port? Are you trying to connect to it over telnet or SSH? Do you know if there is any config on this switch already?
Can you also provide a screenshot of what the terminal shows when trying to connect over the console port?
Thanks for you patience again. I have collected the related inforamtion and pls find the attachment for your reference.
Dear Ben, On you PC set the default gateway to 172.16.233.214, Then telnet to 172.16.233.214.
If the SW has no configuration you may try the following credentials :
User ID: su
Password: wwp
Dear Kazi :
I have solved this promble with your help, thanks so much. The solution is I reseted the switch back to factory defaluts as Mark Costin told me.Then using the IP address through the MGMT port as you told me,thank you!
Ben ...
1/ firstly try turning off the rts/cts flow control in the serial config setting ... shoud not be on .. i have seen this cause problems in the past.
2/ secondly try the reset switch on the chassis. You will see a small hole on the front panel near the console port. Push a paper clip into the hole and hold for 10 seconds. This will reset the switch back to factory defaluts and clear any changes that may be in the config.

Dear Mark：
I finished the test.firstly I turned off the rts/cts flow control ,but it wasn't effective. Then I reseted the switch back to factory defaluts as you told me . I used the MGMT port throungh the IP address as the Kazi Tanvir Ahamed told me. yes,I could enter the interface of the Ciena 3930.
If you're looking for the diagnostic information from the SFP, the command is port xcvr show port <#> diagnostics. You can show more information on the SFP by running port xcvr show port <#>. You can find the manuals in the Ciena portal under Technical Documentation.
as an extra note ... the ability to read the diagnostic info is hardware/manufacturer dependent so not every SFP/XFP etc will support it ... you can use port xcvr show to see if its available .. if the column headed Diag Data says Yes, then it's built into the interface .. if there's no entry in the column then you cannot read the values.
port xcvr show port <#> vendor will give you some extra vendor specific data such as Connector type, (typically LC), Wavelenghth and Serial number
Yes, that's a good point. I was assuming Ciena optics.
