Hi,


I would like to know how to automatically have correct bandwidth under my Dialer Interface who is attached to an ATM Interface.

Command bandwidth inherit doesn't work.


=>

interface ATM0

no ip address

no ip route-cache cef

no ip route-cache

no atm ilmi-keepalive

dsl operating-mode itu-dmt

pvc 8/35

encapsulation aal5mux ppp dialer

dialer pool-member 1

!

end


interface Dialer1

bandwidth inherit

ip address negotiated


sh int atm 0

ATM0 is up, line protocol is up

Hardware is DSLSAR (with Alcatel ADSL Module)

MTU 4470 bytes, sub MTU 4470, BW 928 Kbit, DLY 2200 usec,


sh int di 1

Dialer1 is up, line protocol is up (spoofing)

Hardware is Unknown

MTU 1500 bytes, BW 56 Kbit, DLY 20000 usec,


Bandwidth under dialer is still 56Kbit and under ATM 0 928 Kbit !!!


Thanks

Check virtual-access interfaces.

Yes, interface virtual access 2 got the right bandwidth.


But I have CBWFQ applied under dialer 1 interface so I need to have the right bandwidth for this interface for CBWFQ !

Since VA inherits all configuration from dialer, everything will work as supposed.

Sorry but VA inherit everything but queueing strategy, I've got Dialer 1 with Class-based queueing and VA2 with fifo queueing ?


At least, my question is : is there a command to have bandwidth under dialer1 automatically equal to atm bandwidth ???

That could happen because the default PVC traffic category (UBR) does not allow QoS.


Beside that, it is working as designed, nothing will ever change any configuration under dialer.
