i am trying to get QOS working on our network. having major diffculties in doing this.
what i have 2621 with 10mbps link into our core network and 100mbps in to remote lan.
i been playing around with class maps etc.
has anyone got example gonfig i can follow i followed the cisco format it dosent work. when i run a sniffer on phone it see dscp no ip precendence on the ip packet so this adding more to the confusion .
here my config i been using
class-map match-all QOS
match access-group 101
match access-group 102
bandwidth percent 25
ip address 10.10.10.1 255.255.255.0
service-policy output voicetraffic
ip address xxx.xxxx.xxx.xxx 255.255.240.0
ip route 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx
ip http server
ip pim bidir-enable
access-list 101 permit tcp any range 2000 2002 any
access-list 101 permit tcp any any eq 1720
access-list 101 permit tcp any any range 11000 11999
access-list 101 permit udp any any eq 2427
access-list 102 permit udp any range 16384 32767 any
access-list 103 permit ip any any
Also when i do sho ip access-list it doesnt seem to be using access-list 102
Are you spanning the port the IP phone is connected to on one of your switches? By default Cisco IP phones should tag voice packets with TOS 5 and COS 5.
You should use the access lists to re-classify the TOS value for inbound traffic on the ethernet port. You can then create policy maps for outbound traffic on the fast ethernet port to assign priority to voice traffic and bandwidth for signalling given the dscp/IP precedence of the packet going out on this interface.
All you have done in this configuration is create a class that assigns 25 percent of the interface bandwidth (in the event of congestion) for all the traffic defined in the access lists. Are you finding you have congestion on your 100MB link?
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
