Today I’ve discovered that the infamous dot1x bugs where you can see sessions on interfaces but mac addresses are not visible on interfaces is not limited to supervisor 6 and 7, but also affects supervisor 8 in version 3.6.5a (15.2.2.E5a)
- looping dot1x sessions (buggy supplicants never giving up)
- a lot of dot1x clients
lack of mac address on the port, UNKNOWN sessions in show auth session output
After a while your dot1x machines have intermittent connectivity problems, even if you set auth open on the port.
I’ll try upgrading to the 3.6.8.
Btw an upgrade to 3.8.x train requires a rommon upgrade. I wonder how many people forget to read the rommon documentation 😀
