Hello Chaps,
Has anyone come across situations where traffic gets spilled into
class-map class-default?
I have 2 class-maps ... Class-map CodecA matching traffic from a
particular host, the other is the class-default class-map.
Then a Policy-map with priority set up for the CodecA class-map and then
fair-queing for the class-default.
After series of testing, I discovered that my golden cisco box is
spilling some of the codecA traffic into the class-default which are
hence subjected to delay during congestion.
Just wondering if anyone has good pointers for me, because my head is
about to burst off my neck now as I've had by far, the most troubled
week of my 2008! I've hardly slept, so maybe I'm missing something.
Another thing worth noting is there is GRE-IPSec tunnel between the 2
Routers, and "qos pre-classification" has been dealt with in line to
Cisco best practise of implementing QoS+VPN (I used qos pre-classify
command on the crypto-map and also the tunnel interface, since I'm doing
ecryption and tunneling at the same time, service policy applied
outbound on Router's "WAN" facing interface)
!
class-map match-any CodecA
match access-group name fromServerA
!
policy-map Codec
class CodecA
priority 1000
class class-default
fair-queue
!
ANY HELP WILL DO BEFORE I GO NUTS!
Many Thanks
Yemi Salau
