Hi Guys,
I thought I'd post a question in the forum, although its been a few months
since I passed my lab (thanks again for all your help with that, folks).
I'm trying to setup an outbound QOS policy on a Dialer interface that's used
to establish a PPP link over ATM (for ADSL on a Cisco 3620 router).
Unfortunately, when I apply the policy to the Dialer interface, the QOS
settings don't get cloned to the virtual-access interface with the
configuration on the router as it currently stands. I've tried applying the
policy to both the ATM PVC, the subinterface and the interface and none of
them work. On the Dialer interface, it applies with a warning requiring me
to use Multilink with PPP and I applied that into the Dialer interface
(albeit the ISP router at the other end isn't using multilink).
If anyone has any suggestions it would be greatly appreciated - I've googled
and haven't found any definitive answer as to why it isn't applying.
I'm tempted to try a virtual-template for the PPP as the Dialer isn't really
necessary for the link, but I haven't played much with ATM and was hoping
for some guidance before I experiment during an outage window (there was
enough stuff on the R&S lab, I thought, but now I wish there had been a
little more.).
The IOS is 12.3(22) Enterprise Feature Set and the relevant config and show
commands are below.
No prize, just thanks and a promise of help in return, for any assistance
you can offer on getting the QOS policy to apply. :-)
