Hello
I have 802.1x configured on my Cat 3560 switch stack. For the most part everything works fine but I keep running into users who have printers that go into sleep mode and then the port reverts to a dead default vlan99. When the user goes to print to the printer it is unable to come out of the default vlan99. Below is how I have the port configured. Has anyone else experienced this problem? If so how did you fix it?
interface GigabitEthernet1/0/1
switchport access vlan 99
switchport mode access
authentication order dot1x mab
authentication priority dot1x mab
authentication port-control auto
authentication periodic
authentication timer reauthenticate server
mab
dot1x pae authenticator
dot1x timeout server-timeout 30
dot1x timeout tx-period 3
dot1x max-req 3
dot1x max-reauth-req 3
spanning-tree portfast
spanning-tree bpduguard enable

change them
authentication order dot1x mab
authentication priority dot1x mab
into
authentication order mab dot1x
authentication priority dot1x mab
these above commands are for devices which are dump. i mean those not support dot1x/or dont have a supplicant. the order of authentication will be mab than dot1x.
please do rate if i help you.

Sheraz,
This has seem to stabilize the printer. I applied the config change to the printer port after that I bounced the port and it has been stable.
