This page assumes you've already followed the update/config guide for your specific switch model. You should now have an updated switch configured with an IP address, and one of the **regular switch ports** (not the dedicated management port) plugged into your network to access said IP. It's also assumed you're at the `configure terminal` CLI level.
Nothing here is necessary for your switch to continue operating as a "dumb" unmanaged switch, but the steps here are highly recommended nonetheless to set up basic security, management, and advanced features you might find useful.
Before we can do things like SSH to the switch or access the web UI, we need to do a couple things. First, tell it to generate an RSA keypair - this is the first step to enabling SSH access:
If you wanted to use the web UI (I don't recommend using it, really), you can now log into it using the credentials you created above. By default, the web server is http only. If you want to disable the web server, just run:
```
no web-management http
```
If you would like to then turn on the web server over `https` instead, run the following (skip this if you just want the webserver off totally):
```
crypto-ssl certificate generate
web-management https
```
Once you get an `ssl-certificate creation is successful` message in the console, you'll be able to access the web UI via `https`.
If your switch is outside of your home, or accessible by others, telnet should be disabled entirely, and access to the serial console should also be password protected. Otherwise skip this step at your discretion:
If you have followed the above to set up authentication, and also wish to disable password-based SSH login and set up a key pair instead, follow this section. If not, skip it. Enable key login, and disable password login:
```
ip ssh key-authentication yes
ip ssh password-authentication no
```
Now we have to generate our key pair with [puttygen](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html) on windows or ```ssh-keygen -t rsa``` on linux. The default settings of RSA @ 2048 bits works without issue. Generate the pair and save out both the public and private key.
>The ICX6xxx series do *not* support 4096 bit keys - when using `ssh-keygen` or `puttygen` etc, you must create 2048 bit keys.
Copy the public key file to your TFTP server. Then use the following command to import it into your switch:
```
ip ssh pub-key-file tftp 192.168.1.8 public.key
```
You shouldn't need to be told basic key management if you're following this section, but just in case - copy your private key to the proper location on the *nix machine you'll be SSH'ing from, or if you're on windows, load it using [pageant](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html). Now when you SSH to the switch, it will authenticate using your private key.
Your switch now has a name, an IP address, and telnet or SSH access enabled. You should now be able to get rid of the serial cable and use a program like Putty to SSH or telnet to the switch IP. Then you can continue the guide from that CLI.
If you want your switch to be able to contact NTP servers for time synchronization, remote SNMP servers, etc, we need to give the switch a default route and a DNS server. Replace the IP with the IP of your gateway/router/etc. Assuming you are still at the ```configure terminal``` level:
To have the switch keep its time synced via NTP (so its logs make more sense), use the following. If you live in an area that doesn't use Daylight Savings, skip the ```clock summer-time``` command. Use tab completion for the timezone command to see what's available. The IPs in the following example are Google's NTP servers and work well for most cases:
Whenever you make changes (like above) they take effect immediately, however they are not saved to onboard flash. So if you reboot the switch, they will be lost. To permanently save them to onboard flash, use the following command:
To exit the CLI level you are at, use `exit`. So assuming you are still at the ```configure terminal``` level, type the following to exit back to the ```enable``` level:
```
exit
```
Commands can also be shortened, as long as they are still unique. So to re-enter the configure terminal level, Instead of typing the entirety of ```configure terminal```, the following will also work:
```
conf t
```
There is also tab help and completion. To see all the commands available at the current CLI level, just hit tab. To see the options available for a certain command, just type that command (like ```ip```) then hit tab a couple times.
If you ever need to remove a configuration option you've added, put a ```no``` in front of them at the appropriate CLI level. For example, if you've set the switch name to `beefbox` and have since changed your mind:
This section will outline some of the more advanced configurations you may want to explore. If you use any of them, don't forget to `write mem` when done to actually save your changes.
If you have a PoE enabled model you'll need to enable power on the ports you have PoE devices plugged into. For example, let's say you've plugged a PoE camera into port 5. Lets enable PoE power to turn it on:
```
interface ethernet 1/1/5
inline power
exit
```
That's it, now you should see the device power on. You can monitor PoE status such as power level, which ports are enabled, and how much power they're using by running the following:
ICX6xxx switches also have something called `legacy inline power` on by default, which detects and powers very old legacy PoE devices that rely on a specific resistance for detection. Devices like this are exceptionally rare and this can occasionally erroneously detect regular devices as legacy PoE units, so let's disable it:
If you have a switch that does not support stacking like the ICX6430, you'll need to run `no legacy-inline-power` at the global configure terminal level instead. If you have a switch stack built, don't forget to run the above for stack unit 2 as well (or however many units you have).
If you'd like to configure an LACP bond on the switch to aggregate 2 or more ports to a server for example, it's pretty easy under FastIron. First you need to meet some basic criteria before creating the bond:
Now create the dynamic (802.3ad) lag, giving it a name of your choice:
```
lag freeNAS dynamic
```
Now you should be at the LAG configuration CLI level for this new LAG. Here's the important part, tell it what ports you want to be in the bond. In this example I'll add two of the 10gbE ports on an ICX6610. If you want more than two ports in the bond, add them to the `ports` command after the first two:
Now we need to specify the primary port. This is the port member of the bond that will act as the single port that controls all bond members in your config. For instance, if your primary port is 1/3/1, then to add your LAG to a VLAN, you'd use `tag int eth 1/3/1` - the switch will then do the same for all the other bond members. Same with any port config, if you want to configure the LACP group, you use the primary port. This is almost always the first port in the LAG, but typically it doesn't matter:
Lastly, we need to deploy the new LAG you've created and only needs to be ran once to enable it:
```
deploy
exit
write mem
```
Assuming the other end (server, other switch, etc) has been configured for LACP correctly, you should see them negotiate and enable all links. You can view the status of bonds using the following:
```
show lag
```
This is what a correctly negotiated LACP link will look like, the most important column typically being the last, with `Ope` meaning operational. If you have something else here like inactive, you have a configuration issue somewhere:
```
Deployment: HW Trunk ID 1
Port Link State Dupl Speed Trunk Tag Pvid Pri MAC Name
1/3/7 Up Forward Full 10G 2 Yes N/A 0 cc4e.24b8.d9d0 XEN-01-1
2/3/7 Up Forward Full 10G 2 Yes N/A 0 cc4e.24b8.d9d0 XEN-01-2
Port [Sys P] [Port P] [ Key ] [Act][Tio][Agg][Syn][Col][Dis][Def][Exp][Ope]
1/3/7 1 1 20002 Yes L Agg Syn Col Dis No No Ope
2/3/7 1 1 20002 Yes L Agg Syn Col Dis No No Ope
```
If you ever need to go back and edit the LAG properties, run the `lag` command again with the correct name:
```
lag freeNAS dynamic
```
Then if you want to add more ports to an existing bond for example, re-run the `ports` command, appending the new ports (don't forget to keep the existing ports in the command, or they will be removed). So, to add two more ports to our example bond:
Brocade does not restrict the use of optics or DACs by manufacturer, they'll take anything given it's the right protocol. However by default, optical monitoring information is disabled unless it sees Brocade or Foundry optics.
You'll need to pick up some official Brocade or Foundry optics. Regardless of what optics you have, you'll first need to enable optic monitoring in general by running `optical-monitor` at the `configure terminal` level.
