Hi all

At the moment we are implementing VOIP (Alcatel) in our company. Since I activated globally on the switches ?MLS QOS? Samba Filetransfer is very slow. All other applications are running with same speed as before (Filetransfer from Windows, Ftp from Unix)

Throughput from Samba:

With MLS QOS enabled about 790 kbytes

With MLS QOS disabled about 9700 kybtes

I have Cisco 6506 (Version 12.2(18)SXF) and 3560 (Version 12.2(25)SEB4) and HP-UX 11.11. and 11.23 running

What other QoS parameters have you defined after enabling MLS QoS?

On the interfaces i configured this options. But for the test i removed the qos settings from the testswitch. I tried this with MLS QOS globally enabled and disabled

Here is the Portconfig of the interface where mls is configured


interface GigabitEthernet3/46

description OMNI PCX Enterprise


switchport access vlan 104

switchport mode access

no ip address

mls qos vlan-based

mls qos trust dscp

spanning-tree portfast


Portconfig of the accessswitches

interface FastEthernet0/30

switchport access vlan 6

switchport mode access

switchport voice vlan 104

duplex full

speed 100

priority-queue out

mls qos trust dscp

spanning-tree portfast

sh mls command from the coreswitch

sh mls qos
