Setting up Brocade ICX6450
Preparation
Download the ZIP below, which contains the firmware files and documentation you'll need.
Brocade v8 Firmware/Docu Zip
SW version: 08030sa
ZIP Updated: 11-03-2018
MD5: 0c02f16a73f75ffd0d30d4cb0085cad0
NOTE: If this switch has already been set up and configured with an IP and you just want to update the software/BL, use the files in the ZIP above to update the switch from inside the booted OS using:
#Skip this whole block if the switch has not yet been configured using this guide!
enable
copy tftp flash 192.168.1.8 kxz10105.bin bootrom
copy tftp flash 192.168.1.8 ICX64R08030sa.bin primary
##update the PoE firmware if you have PoE model.
##If you have the smaller "C12" model, it takes a different PoE file!
inline power install-firmware stack-unit 1 tftp 192.168.1.8 icx64xx_poeplus_02.1.0.b004.fw
reload
Otherwise if this is a new/used switch that has not been configured, do the following:
Connect to the switches serial/console port on the front using a program like Putty (9600 8N1), and connect any of the normal switch ports to your network (do NOT use the dedicated management port).
You need to set up a temporary TFTP server - I recommend Tftpd32 Portable Edition if you're on Windows and don't want to install anything. Point the server to an empty folder to serve files from. From the ZIP, copy the bootloader from the Boot
folder into your tftp server directory. Then, from the Images
folder, copy over the image with "R" in the file name to the server as well. For example, ICX64R08030sa.bin
- the other image with an S in it is switching only, with less features.
Power on the switch while watching your serial terminal - start smashing the b
key until you're dropped into the bootloader prompt, which looks like ICX64XX-boot>>
. If you missed the prompt and it boots the OS instead, pull power and try again.
Now at the boot prompt, we tell the switch to clear all current configs and old keys, so it boots into a fresh state:
factory set-default
To confirm this action, you must send CAPITAL Y
- sending a lowercase y
will just make it abort.
Now just tell the switch to reboot:
reset
It will boot into the full OS and you can continue to the next section.
Note:: if you get an error stating factory set-default
is not a valid command, this means your switch has a very old bootloader. To clear the existing passworded config in this case, do the following:
#only follow this section if factory set-default did not work
no password
boot
#it will boot the OS. Once booted:
enable
erase startup-config
reload
#it will boot fresh with a clear config, then you can move to the next section
Initial Configuration & update
Now that it's booted into the full OS you may get TFTP timed out errors in the console, this is normal. just hit enter until they go away. We'll fix that in the next section. Now to make any changes we must enter the enable level:
enable
Now we enter the configure terminal level to make config changes:
configure terminal
Now we turn off the DHCP client, so it doesn't automatically grab an IP and look for a TFTP config (the cause of the earlier timeout messages):
ip dhcp-client disable
write memory
exit
Note: If during the
ip dhcp-client disable
command you get an invalid input error, your switch probably came with the layer 2 only firmware loaded. In that case, just runip address 192.168.1.55/24
(replace the IP) - this will give it a temporary IP, so it can load the layer 3 firmware. Then skip down to theLoad The New Images
section below, and use those commands to copy in the latest layer 3 firmware and reload. Once the switch comes back up, don't forget to come back and follow this Initial Configuration section all the way through now that you have the proper firmware!
Now just reload the switch so it comes back up without an IP assigned to a port via DHCP:
reload
Once it's back up, enter the configure level again:
enable
configure terminal
We need to give it an IP so we can load the new firmware. By default, all ports are in VLAN 1, so it will behave like a typical switch. First we need to give VLAN 1 its own virtual interface:
vlan 1
router-interface ve 1
exit
Now we need to assign that virtual interface an address. Choose an IP that is unused in your subnet, and out of your DHCP server range (ping it first to be sure it's unused):
interface ve 1
ip address 192.168.1.55/24
exit
write mem
Load The New Images
Now that the switch has an IP address, we can TFTP in the new images, then reload:
exit
copy tftp flash 192.168.1.8 kxz10105.bin bootrom
copy tftp flash 192.168.1.8 ICX64R08030sa.bin primary
reload
Note: if you skipped to this section because your switch had layer 2 firmware on it and a note in the previous section instructed you to, go back above and go through the whole Initial Configuration & update section once the switch finishes rebooting.
The switch will reload, loading the new software. Continue on to the Configuration Details section below.
Configuring Details
Your switch should now be freshly booted with the latest layer 3 firmware image and bootloader. First give the switch a name:
enable
configure terminal
hostname intertubes
Now tell it to generate an RSA keypair - this is the first step to enable SSH access:
crypto key generate rsa
Update PoE Firmware
If your switch is the PoE model, you need to update the PoE controller firmware. If it's a non-PoE model, skip this step. Assuming you completed the previous section, just put the icx64xx_poeplus_02.1.0.b004.fw
file on your TFTP server and pull it in.
Note: if you have the small C12 version of this switch, use the icx64xxc12_poeplus_02.03.09.fw
file instead.
exit
inline power install-firmware stack-unit 1 tftp 192.168.1.8 icx64xx_poeplus_02.1.0.b004.fw
#after a few seconds, hit enter to return to cli
#save changes you made from the previous section
write memory
#reload the switch
reload
#you'll probably get a message that it hasn't finished. it can take up to 10 minutes
#run "show log" occasionally to monitor the update progress
#once you're rebooted it back into the OS:
enable
configure terminal
That's it!
If Access Protection Is NOT Required
If you do not want to password protect access to the switch (you're using it in a lab), follow this section. If you'd like to password protect it, skip to the next section.
Allow SSH login with no passwords configured:
ip ssh permit-empty-passwd yes
If Access Protection IS Required (or WEB-UI Access)
If you do want to secure access to the switch, or use the (limited) web UI, follow this section. If not, skip it.
To secure the switch, we need to create an account - "root" can be any username string you wish:
username root password yourpasshere
We also need to tell it to use our new local user account(s) to authorize attempts to log in, use the webpage, as well as attempts to enter the enable
CLI level:
aaa authentication login default local
aaa authentication enable default local
aaa authentication web default local
If you wanted to use the WEB UI, you can now log into it using the credentials you created above.
You should enable authentication for telnet access as well:
enable telnet authentication
If your switch is outside of your home, or accessible by others in any way, telnet should be disabled entirely, and access to the serial console should also be password protected. Otherwise skip this step at your discretion:
no telnet server
enable aaa console
OPTIONAL: Key Based SSH Access
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 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.
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 192.168.1.49 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. Now when you SSH to the switch, it will authenticate using your private key.
Saving & Conclusions
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:
write memory
Your switch now has a basic configuration, as well as an IP address you can telnet or SSH to for further configuration.
Some more useful general commands:
Show chassis information like fan and temperature status:
show chassis
Show a table of all interfaces:
show interface brief
To show one interface in detail:
show interfaces ethernet 1/1/1
#Also works for virtual interfaces:
show interfaces ve 1
Give a port a friendly name:
interface ethernet 1/1/1
port-name freenas
show interfaces brief ethernet 1/1/1
exit
Show the running configuration:
show run
Show the system log:
show log
To remove configuration options, put a no
in front of them at the appropriate CLI level:
no hostname intertubes
Tips
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.
Advanced Configuration
Default Route & DNS
To give the switch a default route and a DNS server so it can reach external hostnames and IP's (to ping external servers or to update time via NTP etc), do the following. replace the IP with the IP of your gateway/router/etc. Assuming you are still at the configure terminal
level:
ip dns server-address 192.168.1.1
ip route 0.0.0.0/0 192.168.1.1
NTP
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 IP's in the following example are google's NTP servers and work well for most cases:
clock summer-time
clock timezone gmt GMT-05
ntp
disable serve
server 216.239.35.0
server 216.239.35.4
exit
SNMP
To quickly enable SNMPv2 (read only), follow the below. SNMP v3 is available but you'll have to refer to the included documentation:
snmp-server community public ro
SFP/Optics Information
Brocade does not restrict the use of optics by manufacturer, they'll take anything given it's the right protocol. However optical monitoring information is disabled unless it sees Brocade or Foundry optics.
So if you want to see information like this :
telnet@Route2(config)#sh optic 5
Port Temperature Tx Power Rx Power Tx Bias Current
+----+-----------+--------------+--------------+---------------+
5 32.7460 C -002.6688 dBm -002.8091 dBm 5.472 mA
Normal Normal Normal Normal
You'll need to pick up some official Brocade or Foundry optics on ebay, or buy some flashed optics from FiberStore.
