VLAN Leaks?
Posted: Thu Feb 01, 2018 11:45 pm
I can't put my finger on this, but I feel like there is some kind of VLAN leak that happens at times.... an example:
SWITCH A
Port 1 - VLAN5 -- airFiber5
Port 2 - VLAN5 -- airFiber24
SWITCH B
Port 1 - VLAN 5 - airFiber5
Port 2 - VLAN 10 - airFiber24
All VLANs are untagged on both sides.
Upon the airFiber24 link coming up traffic across all links will begin to drop packets and the traffic going through the switch degrades until this "loop" is broken. STP and Loop Protection never kicks in. In theory the traffic should never see itself because the VLAN number changes and terminates at the SWITCH B airFiber24. But just the same, when that second link is brought online, the moment it links up packet loss starts happening all over both switches.
I have tried this with the most recent firmware.
