Hi,
I have DOT1X authentication configured on all switch ports. I also have Cisco IP phones.
My requirement is: to allow Cisco IP phones without DOT1X authentication..
Is this possible?
Kindly suggest..

So do you have PC connected behine the phone, If yes and you just want to authenticate PC via DOT1x and bypass the uathentication for your IP phones then You need to use single-host mode command on the concern ports to disable authentication of the IP phone.
dot1x host-mode single-host
dot1x port-control auto
For newer version use these command
authentication host-mode single-host
authentication port-control auto
Also, you need to disable 802.1x on the IP phones.

Hi
By enabling forced authorization on a port, the clientless hosts can connect to it and still be part of the trusted VLAN. This has the same effect as not enabling dot1x on the port. This can be particularly useful if a user wants to connect an IP phone or other device that does not have a supplicant but still needs to be part of the secure VLAN. Any host can be connected to this port and be part of the secure VLAN without going through 802.1x authentication. Similarly, the port can be forced to be unauthorized. This has the same effect as shutting down the port
