DOT1X Dynamic VLAN assignment

Hi Team,

 

Our dot1x is used for dyamic VLAN assignement and it works using this config:

 

int fa0/12

switchport access vlan A

switchport mode access

switchport nonegotiate

authentication event fail action authorize vlan A

authentication event no-response action authorize vlan A

authentication host-mode multi-host

authentication open

authentication port-control auto

authentication violation restrict

dot1x pae authenticator

dot1x timeout quiet-period 1

dot1x timeout tx-period 6

dot1x max-reauth-req 10

spanning-tree portfast

exit

 

However, we noticed that it first goes to VLAN A then goes to the VLAN B. This was an issue with on a client. So i was trying to create a setup that doesn't pass through the VLAN A but passes through VLAN 1 which is unrouted. This is my config:

 

int fa0/13

switchport mode access

switchport nonegotiate

authentication host-mode multi-host

authentication port-control auto

authentication violation restrict

dot1x pae authenticator

dot1x timeout tx-period 6

dot1x max-reauth-req 10

spanning-tree portfast

exit

 

 

It does work but only if the username is already cached in the windows PC. If I login using the same username in a new PC, it doesnt. What am I missing???

 

Please help.

 

Thanks in advance!
