Ciena makes Ethernet & Optical switches for the service provider market. There’s essentially zero publicly available documentation available which is a shame because they make some interesting equipment and as carriers upgrade there’s a lot of used equipment available that smaller providers can put to good use. I’m not sure why it’s traditional for telco-oriented companies to be stingy with their documentation but it’s annoying.
I have some LE-311v, 3911, and a 3940 here for a project so here’s my notes. They are applicable to all devices as far as I know unless otherwise noted.
This also applies to devices running World Wide Packets LE-OS. Ciena acquired WWP and built their packet Ethernet offerings on tech from the acquisition.
CLI is subject-verb instead of verb-subject (think “interface show” not “show interface”). “configuration” enters config mode.
Configuration is a blend of Cisco & Juniper Style:
You can view the current configuration with:
configuration show
The configuration is displayed as a sequence of commands that are entered to achieve the desired state when you are starting from the default state.
You save the configuration with: save
You have to be in configuration mode to save the config but you don’t have to be configuration mode to change the configuration.
You can navigate the configuration in a sort of tree format as on a Juniper or Mikrotik device. For example you can enter “interface remote show” to view management interface status or you can enter “interface remote” and then “show” or “set” as appropriate.
I found someone else’s notes on configuring Ciena devices that covered this and got me started.
On the LE-311v and 3940 there’s a pinhole reset button. There’s three options:
There are two default users: su & user. su is the superuser with a default password of wwp. user doesn’t have a password.
My devices have a DB9 serial port. You’ll need a null modem cable for this. The 3911 has DB9 port visible from the user compartment but if you remove the inner cover to the carrier compartment you’ll see that it’s just a jumper to a Cisco-style cat5 console port.
The serial ports use the typical console settings of 9600 baud, 8 data bits, 1 stop bit, no parity (9600 8N1).
The LE-311v & 3940 have a ethernet management port for local access. The local access part is important. You can plug your laptop into it. You can’t put a default gateway or other route on it and hook it up to your out of band network.
Management IP: 172.16.233.214/24.
You can see current settings with: interface show local
For example:
lab> interface show local
+----------------------------------- local -----------------------------------+
| Parameter | Operational | User | DHCP |
+----------------------+-------------------+-----------------+-----------------+
| IP Address | 172.16.233.214 | 172.16.233.214 | 0.0.0.0 |

| VLAN | 0 | | |
| Priority | 0 | | |
| MTU | 1500 | | |
+----------------------+-------------------+-----------------+-----------------+
Out of the box you should be able to plug in, set you a IP in the subnet on your laptop, and telnet in.
You can see the current users with: user show
For example, with default users:
CN 3911> user show
+--------- USER ACCOUNT TABLE -----+-------+
| Username | Privilege | Flags |
+------------------+---------------+-------+
| su | super | DP |
| user | limited | D |
+------------------+---------------+-------+
Removing the read-only user: user delete user user
CN 3911> user delete user user
CN 3911> user show
+--------- USER ACCOUNT TABLE -----+-------+
| Username | Privilege | Flags |
+------------------+---------------+-------+
| su | super | DP |
+------------------+---------------+-------+
Adding a management user:
user create user labadmin access-level super password blah123
Changing the password for the built-in user “su”:
user set user su password blah123
Check OS version with: software show
For example:
lab> software show

I’m testing with a WWP-branded LX SFP and a Hoyos Consulting-branded GLC-T SFP that identifies as Cisco SFP.
My LE-311v doesn’t show a difference between the SFP modules. The 3911 shows a difference (GLC-T in 9, LX in 10):
CN 3911> port show

You can see the type of transceiver with port xcvr show:

The port will still come up and pass traffic with a uncertified transceiver.
