I'm on a Cisco 877 here, and am just setting up a voip phone. I want to make sure that voip traffic gets prioritised as much as possible, so came up with the following config. Is there anything else I should be doing or thinking about, or any obvious problems? It seems to work ok, with voice quality being ok whilst a big torrent and lots of http downloads are going on.
POLICY is then applied outbound on ATM0.
Code:
class-map match-any BESTEFFORT
match protocol http
match protocol secure-http
match protocol icmp
match protocol secure-imap
match protocol smtp
match protocol ipv6
match protocol ssh
match protocol dns
class-map match-any REALTIME
match protocol rtp
match protocol rtcp
match protocol sip
class-map match-any SCAVENGER
match protocol bittorrent
