The priority tagged packets might not be stripped causing connectivity issues

When the dot1x client connects to the EX using the dot1x authentication, the priority tagged packets (like ARP, ICMP, etc. )might not be stripped causing connectivity issues. It might impact the dot1x client connectivity not to work after authentication.


L2 traffic might be impacted if the vlan name given in 'show vlan' contains more than 169 characters

On legacy platforms (EX3200, EX3300, EX4200, EX4500, EX4550, EX6200, EX8208, EX8216, EX-XRE, QFX3008-I, QFX3600-I, QFX3500 and QFX3600), if the vlan name given in 'show vlan' contains more than 169 characters, the eswd might crash and L2 traffic and vmember based traffic might get impacted. Spanning tree service might get impacted as well.


LLDP does not work on management interfaces me0/vme0

The Link Layer Discovery Protocol (LLDP) allows network devices that operate at layer 2 to learn some of the capabilities and characteristics of LAN devices available to higher layer protocols, such as IP addresses. On EX2200/EX3300, LLDP packets cannot be received on management interfaces me0/vme0, then LLDP adjacency fails to be established. This issue has service impact.
