802.1x and ATA

[ak7246]

hello Team,

I am trying to configure 802.1x on the 2560 switches. We have some ATAs connected. I configured the MAB on the switch and configured the windows IAS server with the ATA MAC as user/password. However; when i connect the ATA to the switch port it doesn't get the IP address. Is there a way to make this work? here's my switch port config.

interface FastEthernet0/29

switchport access vlan 17

switchport mode access

switchport voice vlan 3030

srr-queue bandwidth share 10 10 60 20

srr-queue bandwidth shape 10 0 0 0

priority-queue out

mls qos trust device cisco-phone

dot1x timeout supp-timeout 10

dot1x reauthentication

dot1x guest-vlan 999

dot1x auth-fail vlan 999

dot1x auth-fail max-attempts 2

I appreciate your help.

thanks

Try to assign static IP address. You can verify which IP address was assigned to the Cisco ATA with the IVR menu.

The Dynamic Host Configuration Protocol (DHCP) server is enabled by default from version 2.x and later. When the DHCP field is set to 1, the Cisco ATA 186 contacts the DHCP server to get the IP address, subnet mask, and default route.

If anyone is still looking for an answer, one needs to enable Voice Domain Permission in the Authorization profile for ATA to get the DHCP IP.
