i got a MFSYS25V2 with 2 Switches.
Since upgrade to firmware version 11.5 i have the following problem.
On both switches i configured a VLAN with e.g. VLAN-ID 55 on only one single external port as untagged, not on the 10G.XC interlink port.
I also have two Dell PowerConnect switches.
When i connect these components as show in the graphic below, i get a loop.
- The 10G.XC interlink is not member of the VLAN-ID 55.
- all Servers are shut down
- jumbo frames on all switches are enabled (also tried with disabled)
Is there a known bug in the new firmware version 11.5?
For all versions of firmware, not just 11.5, it is recommended to keep that link disabled.
Thank you for answering.
I'm using this 10G.XC link for several VLANs.
Only a single one should be used like described in my question.
So my question is answer but the problem still exists.
You can disable that link, regardless of VLAN assignment.
