Moved your post from the pictures thread.

Why can you not get to the UI via http?

The switch seems to no longer power the main uplink (AF5x) where the default route goes This cable I want to test.

Additional Info. I changed default gateway and disabled the route at the uplink router to route via the backupline.
But I did a port bounce before with cli to restart the AF5X. This seem to kill the webinterface. So I still can only ssh into the switch.

I cant find the command to remove the port bounce with cli.

If this a version of firmware older than v1.4.3rc4 which has a fix where if you do a port bounce in the CLI it corrupts your config file.

Really sorry about that but this bug was just found a couple weeks ago.

I know, what are the odds right, sorry about this.

I am sure Eric would know how to better help you but I personally would factory default the unit and manually set it backup at this point.

I have pinged Eric to try and help you.


One other possible way to fix this would be to do a firmware upgrade to v1.4.3rc4 via the CLI but you would need a TFT server to do this as v1.4.3rc4 will fix the config file corruption.

To do a CLI upgrade press "?" and look for help
You see a list of commands and firmware is one of them

Then type "firmware upgrade <tftp URL>

EXAMPLE TFTP URL: tftp://server/path-and-filename
"

Use the "show bounces" command to see the configured bounces.

Code: Select all

 
Netonix Switch# show bounces
Number Port Enable Description Cut Power For Schedule Type Day Of The Month Hour Weekday
------ ---- ------ ----------- ------------- ------------- ---------------- ---- -------
1 5 true (null) 5 Daily 1 4 Sunday


This shows bounce #1 on port 5 with a null description (which is what is causing the problem).

To fix it you would do this in the CLI

Code: Select all

 
config
int port 5
bounce 1
description foo
exit
exit

 

The web interface should now work again.

Thanks. This did the job. Did a cable test and got the info that cable pair 1 is shorted with cable pair 2. So something happened to the cable.

It would be a good idea for the case that the primary uplink fails to have some backup ip mechanism on the switch. So a second IP/gateway on a second vlan which is enabled when ping to the uplink gateway fails. To reach the switch, routing has to be changed. So the other side of the uplink is not reachable then until routing is changed back.
