How to Fix Routing code issues on Lennar Home users

[Vásquez_Fer]

A common Lennar environment is a router and one or more APs connected to the ICX-7150, this can include multiple smart devices connected through cable or Wi-Fi.

Some symptoms when the ICX 7150-c12p is running Routing code:

Smart devices like Amazon's Alexa not working as intended.
Unleashed dashboard sometimes not showing as "Connected" on the Internet tab.

Websites not loading.
Several connectivity issues.

This can happen for a multitude of reasons: Maybe the boot preference was not set when configuring the device, maybe the device was never configured and the routing code was set on the primary flash or maybe the images got corrupted after a power outage or a power spike, random reboot, among other possible causes.

1- To fix this, the switch must be accessed via console/telnet or ssh

Default passwords: username: super password:sp-admin or try to use the same as the same to log in unleashed dashboard or mobile app 

2-Once we are log in into the switch, we should see the next prompt

ICX7150-C12 Router>

Where it immediately tells us that the routing code is running.

3- Must go to Privilege mode

ICX7150-C12 Router>enable           'then Hit Enter to accept the command'

4-Run a ‘show version’ to confirm which code is running your ICX 7150-c12p

-Show version

ICX7150-C12 Router#show version

as we can see in the initial of the output, SPR08080f is being executed, where the third letter means that the switch is executing the routing code.

Important Note

In Lennar homes, the switch must run SPS (switching) and not SPR (routing) code

5-Once the information is confirmed from the ‘show version’ we should run a show flash

-Show flash

ICX7150-C12 Router#show flash

Stack unit 1:

  NAND Type: Micron NAND 2GiB (x 1)

  Compressed Pri Code size = 25976488, Version:08.0.80fT211 (SPS08080f.bin)

  Compressed Sec Code size = 29829112, Version:08.0.80fT213 (SPR08080f.bin)

  Compressed Boot-Monitor Image size = 786944, Version:10.1.14T225

  Code Flash Free Space = 1057533952

Here we can see that both SPS is installed in the primary image and SPR is installed in the secondary on the switch.

Here to prevent this problem in the future is to run a ‘copy flash flash secondary’ What this is going to do this command is to copy the primary image in to the secondary image, eliminating the SPR image.

Note: if your switching code is in the secondary code we must execute ‘copy flash flash primary’

- ICX7150-C12 Router#copy flash flash ‘primary or secondary’

  primary       Copy secondary to primary

  secondary     Copy primary to secondary

Once the command is executed is going to re-flash the images:

ICX7150-C12 Router#copy flash flash secondary

ICX7150-C12 Router#Load to buffer (8192 bytes per dot) ...................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

.............................................................................................................................................................................................................................................................................................................................................................................................................Copy Done.

6-Once the Step ‘5’ is completed we should run a ‘show flash’ again to verify that both images are running switching code SPS

-Show flash

ICX7150-C12 Router#show flash

Stack unit 1:

  NAND Type: Micron NAND 2GiB (x 1)

  Compressed Pri Code size = 25976488, Version:08.0.80fT211 (SPS08080f.bin)

  Compressed Sec Code size = 25976488, Version:08.0.80fT211 (SPS08080f.bin)

  Compressed Boot-Monitor Image size = 786944, Version:10.1.14T225

  Code Flash Free Space = 1057533952

7- when completing all the previous steps we execute a 'reload' and confirm the reload of the switch

Note:also you can force the switch to boot up in a specific image:

Boot system flash primary yes ‘to boot up the switch in primary image‘

Boot system flash secondary yes ‘to boot up the switch in secondary image‘

-Reload

ICX7150-C12 Router#reload

Warning: Console login authentication is enabled, please make sure users are configured

Are you sure? (enter 'y' or 'n'): y

Running Config data has been changed. Do you want to continue

the reload without saving the running config? (enter 'y' or 'n'): y

8-we should get access to the switch again

ICX7150-C12 Switch>

Here we see that the switch is running the correct code ‘switching ‘

 go to the privileged mode and confirm with a show version that the switch is finally running SPS code

-Enable ‘go to privilege mode’

-Show version ‘Check actual version ‘

ICX7150-C12 Switch>enable

Note: This may be a fix for some users, sometimes the flashes get corrupted, and you need to proceed with an upgrade to the same version or later.

Many times, the copy flash flash does not work properly, and we must run it more than 1 time or reboot the switch and run it.
