Loop detection and handling on EX4200 / EX3200 on trunk ports
[ Edited ]
Hello, we are replacing an Cisco swith with EX4200 / EX3200. The switch has no access ports, all ports are trunks.
In case of loop in a VLAN, our Cisco isses a MAC FLAPPING warning (SW_MATM-4-MACFLAP_NOTIF). Similar functionality we use on Edge-Core switches, this is called Sticky MAC and prevents re-learning MAC on the wrong port. In both cases, we know that a loop occured and know affected MACs, VLANs and ports.
Is it possible to achieve a similar functinality on *trunk* (!) ports for EX4200 / EX3200 - i.e. some MAC move/flapping, sticky MAC or any other kind of (indirect) loop notification ?
There is a requirement for spanning tree to be disabled.
For access ports, secure-access-port setting works fine, but for trunks I did not find anything usable.
