Morning all,
I would appreciate some opinion and or guidance on this. I was working on a QoS solution based on classes and DSCP markings for a WAN interface. The decision was then made to change that plan and do the QoS on the LAN side as opposed to the WAN link. I have a 4507 with SVI's which addresses routing between the VLANs. Below is an example of how my configuration
!
Class Map match-any NETWORK0-MNG (id 3)
Description: **** NETWORK MANAGEMENT TRAFFIC ****
Match protocol telnet
Match protocol ssh
Match protocol ntp
Match protocol snmp
Class Map match-any UNWANTED (id 4)
Description: **** TRAFFIC WHICH CAN BE DISCARDED OR MARKED DOWN ****
Match protocol gnutella
Match protocol kazaa2
Match protocol edonkey
Class Map match-any class-default (id 0)
Match any
Class Map match-any BULK-DATA (id 5)
Description: **** OTHER IMPORTANT TRAFFIC ****
Match protocol ftp
Match protocol http
Match protocol dns
Match protocol exchange
Match protocol secure-pop3
Match protocol imap
Match protocol smtp
Match protocol notes
Class Map match-any VOICE (id 6)
Description: **** MATCH VOICE TRAFFIC ****
Match protocol rtp audio
Class Map match-any MISSION-CRITICAL-DATA (id 1)
Description: **** USED FOR MISSION CRITICAL DATA ****
Match protocol citrix
Match protocol sqlserver
Match protocol ldap
Match protocol kerberos
!
Policy Map MY-TRAFFIC-MNG
Description: *** THIS POLICY IS USED TO MANAGE MY WAN TRAFFIC ****
Class MISSION-CRITICAL-DATA
set dscp af31
Class BULK-DATA
set dscp af11
Class VOICE
set dscp ef
Class NETWORK0-MNG
set dscp cs2
Class UNWANTED
set dscp cs1
Class class-default
Flow based Fair Queueing
Bandwidth 0 (kbps) Max Threshold 64 (packets)
Now my question is how do I make this work on the LAN via the 4507. Do I do VLAN based QoS or do I do it port based. In addition, how will the markings be trusted by the other devices (switches, routers) in the path?
Please feel free to offer any comments, suggestions, tips, criticism, etc
Thanks
