I am doing this migration with these 3com switches.So our client told me that the configuration was made for a network administrator who was fired some years ago. So I dont have any kind of documentation so I need to figure what does each command. I am having trouble with 2 ACL and a QOS policy.
Configuration:
#
acl number 3997
rule 0 permit ip dscp ef
rule 1 permit tcp destination-port eq www
rule 2 permit udp destination-port eq snmp
rule 3 permit udp destination-port eq snmptrap
rule 4 permit ip dscp cs6
rule 5 permit ip dscp cs7
#
acl number 4999
rule 0 permit type 8868 ffff
rule 1 permit source 00e0-bb00-0000 ffff-ff00-0000
rule 2 permit source 0003-6b00-0000 ffff-ff00-0000
rule 3 permit source 00e0-7500-0000 ffff-ff00-0000
rule 4 permit source 00d0-1e00-0000 ffff-ff00-0000
rule 5 permit source 0001-e300-0000 ffff-ff00-0000
rule 6 permit source 000f-e200-0000 ffff-ff00-0000
rule 7 permit source 0060-b900-0000 ffff-ff00-0000
rule 8 deny dest 0000-0000-0000 ffff-ffff-ffff
#
qos-profile default
packet-filter inbound link-group 4999 rule 8
traffic-priority inbound ip-group 3997 rule 0 cos voice
traffic-priority inbound ip-group 3997 rule 4 cos network-management
traffic-priority inbound ip-group 3997 rule 5 cos network-management
traffic-priority inbound link-group 4999 rule 0 dscp ef cos voice
traffic-priority inbound link-group 4999 rule 1 dscp ef cos voice
traffic-priority inbound link-group 4999 rule 2 dscp ef cos voice
traffic-priority inbound link-group 4999 rule 3 dscp ef cos voice
traffic-priority inbound link-group 4999 rule 4 dscp ef cos voice
traffic-priority inbound link-group 4999 rule 5 dscp ef cos voice
traffic-priority inbound link-group 4999 rule 6 dscp ef cos voice
traffic-priority inbound link-group 4999 rule 7 dscp ef cos voice

The ACL 3997 is an ACL for the QOS policy. Is the interesting traffic. I understand that. The second one is a list of MAC addresses allowed in the same QOS policy.
And finally the QOS policy. I have zero experience working with QOS politics in switches. I dont understand how to migrate the QOS policy. I have found some examples but since I dont understand what I am doing I dont want to copy paste a configuration and hope for the best results. Any good resource for a quick crash course for QOS. at least the basic to understand this policy.
Or if you have the time explain me here what is the meaning of each command.
Thank you
