Nexus 7000: STP problem with CTS applied in L2 Trunk
We have two Nexus 7000 connected by a Gigabit link (without redundant). NX-OS version is 5.2.1.
In this link we have configured CTS in manual mode for MACSEC. This link is a trunk that transport several vlans and the STP works correctly. The STP configured is RPVST. Then, the root is sending BPDUs every 2 seconds(for vlan).
If we send traffic (200 mbps), in certain moment the nexus stop the ship of BPDUs. Sometimes are 4 seconds, other 10 seconds, then the other Nexus take the control of STP and start to send BPDUs. Then we have the standar cicle of STP(blocking,...) and 30 seconds without sevice.
If we disable STP, we can have 900M of traffic without any loss.
If we disable CTS, the STP works correctly (with 900M of traffic).
Do you know any incompatibility of STP and Trustsec? Any workaround(different to disable STP or BPDU-Filter?
