I use the GE interafce of Cisco 2821 as PPPoe client and connect to non-Cisco ADSL modem to access Internet. But can't establish the PPPoe session

The following is my configuration (My IOS version is 12.4):

interface GigabitEthernet0/1

mtu 1452

no ip address

duplex auto

speed auto

pppoe enable

pppoe-client dial-pool-number 1

interface Dialer1

mtu 1492

ip address negotiated

encapsulation ppp

dialer pool 1

dialer-group 1

ppp authentication chap callin

ppp chap hostname username

ppp chap password password

end

ip route 0.0.0.0 0.0.0.0 Dialer1

The enclosed is the PPPoe debug information.

Please help me to solve the problem
