Duplicated IP Address

Unanswered Question
Jul 23rd, 2007

Hi List,

Currently, I have a problem with some PPPoE accounts. I configured a Cisco3640 as NAS, and ACS as AAA for PPPoE users authentication. The users that use only one VLAN working fine. However, I have users that uses the same VLAN (different accounts) and the Cisco AAA ACS provide the same IP address:

Vi13 20761 PPPoE 00:00:07 200.110.46.18

Vi14 10080 PPPoE 00:00:00 200.110.46.18

The VLAN (Subinterface) configuration is:

!

interface FastEthernet0/0.6

encapsulation dot1Q 6

ip access-group control-full in

no ip redirects

no ip proxy-arp

rate-limit input access-group 140 136000 25500 25500 conform-action set-prec-transmit 5 exceed-action drop

rate-limit input 72000 24000 24000 conform-action transmit exceed-action drop

rate-limit output access-group 140 136000 25500 25500 conform-action set-prec-transmit 5 exceed-action drop

rate-limit output 72000 24000 24000 conform-action transmit exceed-action drop

pppoe enable

pppoe max-sessions 7

no cdp enable

arp timeout 300

end

!

Please any suggestion for resolve that issue?

Thanks in advanced.

Rgds.
