M4300-28G ip management port fails after restart in a stacked configuration.
Hello,
we have a stacked configuration from 6 times a M4300-28G switch (firmware version 12.0.2.9), the stack up and running.
The ip management port (IP4) is set to vlan 1 and via the web interface all settings en configurations can be seen.
After a restart of the stack (all the swithes go down) the web interface fails and de ip address of the ip management port can't be accessed any more.
After setting the ip address from the ip management port again (via CLI command line interface port) the ip management port is available again.
What can be the reason that the ip management port isn't available after a restart?
best regards,
Jos Laan
Hi Jos,
We have received the TechSupport file just you sent to us.
This error may cause by serviceport enhancement in 12.0.2.x which add a new default IP address 192.168.0.239/24.
We also find a similar issue just like yours which will only appear on slave stack unit.
Maybe this issue have same root cause with yours.(default serviceport IP address)
So We will share the new firmware to you when the similar issue fix.
Please use a workaround method to avoid the error for now if possible:
Set the an another IP address on management VLAN.
Such as:
192.168.1.x/24
192.168.10.x/24
Thanks for your understanding and patience.

Hi JosLaan
Welcome to the community!
One possible reason would be: configuration lives in non-volatile memory, when it's saved. Until it is saved, it is applied in RAM only.
When you configure the switch, it is not saved automatically. Are you using Web Interface (GUI)? A Save button should do it.
I believe you had configured the Management VLAN IP address and clicked on "Apply" button on that GUI page.By Applying the configuration, you save it in RAM and make it work in running config.
But the startup config remains untouched as this point: you should go to Maintenance -> Save Config and click SAVE button to write the running config into the startup config. Only the startup config in non-volatile memory is getting used after a reboot.
Let us know if this helps!

Hello Laurent,
thank you for your explanation, I checked the settings for ip manangement after reboot and they seems ok:
(M4300-28G) (Config)#show ip management
IPv4 Interface Status.......................... Down
IPv4 Management Interface...................... vlan 1
IP Address..................................... 192.168.4.1
Subnet Mask.................................... 255.255.0.0

Burned In MAC Address.......................... B0:7F:B9:42:C6:A4
Locally Administered MAC address............... 00:00:00:00:00:00
MAC Address Type............................... Burned InWhen I change the ip-address (see below) to another address and back again to the original value then the Web Interface will working again.
(M4300-28G) (Config)#ip management vlan 1 192.168.4.2 255.255.0.0
(M4300-28G) (Config)#ip management vlan 1 192.168.4.1 255.255.0.0
Or disconnecting the ethernet cable from the switch and plug it in again, then also de Web Interface will working again.
Very strang!
When logging (via CLI USB port) on the master switch a few message appear (see below) but the stacking configuration looks working well after full startup:

User:After first installing the switches in a stack configuration and connected to our existing network we had a BPDU error message (every 10 sec.), after a firmware update (from 12.0.0.11 to 12.0.2.9) this message was fixed.
Have you any suggestions what we can do?

Hello Laurent,
are there know issues with firmware version 12.0.2.9 M4300-28G switch?
Have you any idea why the ip management port fails to response after a reboot?

Hi JosLaan
No, there is no known issue on 12.0.2.9 so I am very perplex on this Management IP issue.
I originally thought your startup config wasn't properly saved, but that's not the case as we see the IPv4 Interface Status.......................... Down with the right IP address after a reboot. So there is another conflict affecting the VLAN 1 IP interface in startup config, since this interface is down.
Do you have conflicting configuration on OOB port, simultaneously? Can I ask you to follow indications from this post, in order to remove the configuration from the OOB Service Port?
Regards,
Hello Laurent,
OOB port is set:
(M4300-28G) (Config)#show serviceport

When switching from ip management address:
(M4300-28G) (Config)#ip management vlan 1 192.168.5.1 255.255.0.0
Ping works! (to the new address 192.168.5.1).

- Hi JosLaan
I'm sorry for the issue. At this point we're quite convinced there's mismatch configuration or conflicting settings that only Tech-Support export file will divulgate.
Please issue “show tech-support” CLI command and export the file for instance in GUI in Maintenance/Export/HTTP file/Tech-Support file. Please kindly send it to me using PM and we'll closely look at it.
