Dell SmartFabric OS10 User Guide Release 10.5.3

Restrictions and limitations

The following restrictions and limitations apply to these port-security enhancements:

• When port-security is enabled on trunk ports (ports that are connected between two switches) with default mac learn limit (one), if peer switch sends control packets other than LACP, LLDP, and xSTP, it is possible that learn limit is reached immediately without learning a single MAC from the actual data packet. So, the network administrator must set the mac learn limit to accommodate all the MACs that can be learned from nondata packets.
• If a station moves across different secondary VLANs in the PVLAN domain where the source and destination ports are port-security enabled and station move deny is configured with violation action as either Drop or Drop and Log, then the Drop action is not allowed by SmartFabric OS10.
