Solved: Dialer not coming up

DanJay3411401 · ‎07-26-2019

Dear all,

I am in a rural area in southern Germany on a ADSL2+ Line, my C886 VA-W (K9) box trains this as follows:

XTU-R (DS) XTU-C (US)
Chip Vendor ID: 'BDCM' 'BDCM'
Chip Vendor Specific: 0x0000 0x93EF
Chip Vendor Country: 0xB500 0xB500
Modem Vendor ID: 'CSCO' ' '
Modem Vendor Specific: 0x4602 0x0000
Modem Vendor Country: 0xB500 0x0000
Serial Number Near: FCZ185392DV C886VA-W 15.2(4)M
Serial Number Far:
Modem Version Near: 15.2(4)M
Modem Version Far: 0x93ef

Modem Status: TC Sync (Showtime!)
DSL Config Mode: AUTO
Trained Mode: G.992.5 (ADSL2+) Annex B
TC Mode: ATM
Selftest Result: 0x00
DELT configuration: disabled
DELT state: not running
Trellis: ON OFF

Firmware Source File Name (version)
-------- ------ -------------------
VDSL user config flash:VA_B_38V_d24m.bin (10)

Modem FW Version: 170321_1253-4.02L.03.B2pvC038v.d24m
Modem PHY Version: B2pvC038v.d24m
Vendor Version: Bpv38v.24m 68

Here's the relevant part of the config; as this is Annex B the fun stuff happens on the ATM side of things with e0 being shut and (because it's ADSL2+) no tagging on sub-ifs:

interface ATM0
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
no atm ilmi-keepalive
pvc 1/32
oam-pvc manage
pppoe-client dial-pool-number 1

Here's the dialer:

interface Dialer2
description DSL - Uplink
ip address negotiated
ip nat outside
ip virtual-reassembly in
encapsulation ppp
ip tcp adjust-mss 1452
dialer pool 1
dialer string "*99#"
dialer-group 1
ipv6 enable
ppp authentication pap callin
ppp pap sent-username [snip]
ppp ipcp dns accept
ppp ipcp mask request
ppp ipcp route default
ppp ipcp address accept
no cdp enable
crypto map generic

e0:

interface Ethernet0
no ip address
no ip route-cache

shutdown

Dial out Controls:

ip nat inside source route-map natexclude interface Dialer2 overload
ip route 0.0.0.0 0.0.0.0 Dialer2
!
access-list 90 permit 192.168.2.0 0.0.0.63
access-list 120 permit ip 192.168.2.0 0.0.0.255 any
access-list 197 permit ip 192.168.2.0 0.0.0.255 192.168.1.0 0.0.0.255
access-list 198 permit ip 192.168.2.0 0.0.0.255 any
dialer-list 1 protocol ip list 120
!
route-map natexclude permit 10
match ip address 198

egress Traffic is being recognized as interesting as per list 120, but DSL does not come up because of Di2: No free Dialer, and I cannot the heck figure out what I did wrong in the binding. Can some kind person shed some light on this ?

Also, try and leave the configuration as it originally was and remove the dialer string from the Dialer interface:

-> no dialer string "*99#"

Hello,

who exactly is your ISP ? A lot of times the ISPs require you to configure a subinterface. Try the two different ATM interface configs below:

interface ATM0
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
no atm ilmi-keepalive
pvc 1/32
oam-pvc manage
encapsulation aal5mux ppp dialer
dialer pool-member 1

-------

interface ATM0
no ip address
no atm ilmi-keepalive

dsl operating-mode auto
!
interface ATM0.1 point-to-point

pvc 1/32
encapsulation aal5mux ppp dialer
pppoe-client dial-pool-number 1

If that doesn't help, post the entire config...

DanJay3411401 · ‎07-26-2019

ISP Config: Contractor is easybell, Carrier is QSC.

No Luck, here's the config with what you suggested.

I'll check the config and get back with you...

DanJay3411401 · ‎07-26-2019

Thanks Georg, I will now leave office and try to find a slot for testing later whatever you may find.

Georg Pauwen · ‎07-26-2019

Hello,

I have made some changes and additions to your configuration (marked in bold). The Cisco routers are not specifically mentioned on the Easybell support page, so I am not sure if they are supported at all.

You don't need a default route when you have 'ppp ipcp route default' confgured, so I removed the default route.

I have configured aal5snap for the Dialer, give that a try.

Also, some of the DHCP addresses needed to be excluded. Also, the NAT access list needed to exclude the NAT for communication between the local networks.

You also might remove the ATM subinterface and try the same configuration on the main interface.

Hello Georg,

I agree that the dialer string command shouldn't be needed in this context.

Houston, we have Signal !

As soon as I altered the encaps, ppp came up nicely and leaves me with a mediocre 12 down/ 1.something up.

Thanks everyone for your kind and helpful support. I am not too frequently here (I wish I was), but please have my kudos for helping a small company with a few people do its work.

Dan
