The day after I posted this message I indeed found out that I had read
over the MAC address a hundred times without noticing the difference.
Only after pasting them below one another I noticed the difference, and
then the problem was fixed very quickly.
For the option the switch offers to accommodate devices that can't do
802.1x themselves, you say that the solution Avaya offers is stupid.
Could you tell me a solution that works where I can integrate devices
that don't do 802.1x in an environment where all ports need 802.1x?
I only have one LDAP server configured for radius to look at. There are
no other LDAP servers except this one cluster IP. Why do you think the
requests are redirected to other LDAP servers? What part of the debug
log makes you think this?
