pppoe client and IOS 15

[Boris Sharapov]

Hi,

The pppoe on IOS (15 version) does not work (when using 12.4 version- everything is OK)

I have tried it with c880data-universalk9-mz.151-1.T.bin, c880data-universalk9-mz.150-1.M3.bin, c880data-universalk9-mz.150-1.M2.bin - DOES NOT WORK.

But it DOES WORK with c880data-universalk9-mz.124-24.T4.bin.

The configuration

interface FastEthernet4
no ip address
duplex auto
speed auto
pppoe enable
pppoe-client dial-pool-number 1 service-name "xxx"

interface Dialer0
ip address negotiated
ip mtu 1452
encapsulation ppp
dialer pool 1
dialer-group 1
no cdp enable
ppp authentication chap callin
ppp chap hostname xxx
ppp chap password 7 xxx

dialer-list 1 protocol ip permit

The errors are

PPPoE: Failed to add PPPoE switching subblock
PPPoE: Unexpected Event!. PPPoE switching Subblockdestroy called

"normal" IOS bugs.

Use what works, or complain to the TAC.

To the person that rated my post above as "1".

You are a very un-educated person. You come here with the expectation that people has to promptly give a complete solution for your problems, and do not accept a 100% true and correct reply.

If that is not true come forward and voice the the reason why you did low rate my posts.

I don't think that you will.

Unfortunatelly, I can not complain to TAC, because I have no Cisco Service Agreement.

I didn't face any issue in 15.0M with this PPPoE client configuration:

vpdn enable
bba-group pppoe global

interface Ethernet0/0
ip address 192.168.0.1 255.255.255.0
ip nat inside
ip virtual-reassembly

interface Ethernet1/0
no ip address
pppoe enable group global
pppoe-client dial-pool-number 1

interface Dialer1
ip address negotiated
ip nat outside
ip virtual-reassembly
encapsulation ppp
dialer pool 1
ppp authentication chap callin
ppp chap hostname user@surf.org
ppp chap password 0 cisco
ppp ipcp route default

ip nat inside source list 1 interface Dialer1 overload
access-list 1 permit any
dialer-list 1 protocol ip permit

Could you try a similar configuration?

thanks,

Xavier

vpdn enable
bba-group pppoe global
....
pppoe enable group global

Please note that despite whatever documentation saying otherwise, the commands above are NOT needed for PPPoE client, but only for PPPoE server.

I have hundreds of installations running fine without these commands. Admittedly, none use 15.0 yet.

No, unfortunatelly this config wont help me. It  really looks like IOS bugs, if there is no any specific commands for IOS 15.0.

Thanks.

Vladimir,

I am from Cisco TAC and support this technology.

There was a bug opened for this not too long ago.

CSCtg38732    887 adsl Fails to get a Stable Condition

However, this issue was not seen in the latest IOS:  15.1-2T2. Please upgrade to this or a leter ios and suggest if this issue goes away. Also make sure that you are on the latest firmware as well.

Shelley.
