3548 QoS mode trust
Hi,
I am configuring a (powerconnect 3548P) switch for both data and voice, with VLAN1 for data (untagged) and VLAN100 for voice (tagged). Both the PC and IP phone are picking up the right IP addresses, but I am stuck on the configuring of QoS.
I am trying to set the QoS trust as DSCP both from a command line and the GUI but is returns an error of "Voice VLAN and advanced mode/no qos/trust dscp configuration prevention'.
I know it must be something simple but it's doing my head in as I cannot see what I'm doing wrong.
Any help would be much appreciated.

Hi,
Did you enable QoS globally on your switch? It must be set in basic mode. Can you print here show qos output?
And are you sure that IP phone will send traffic with DSCP field, not CoS?

Thanks for your reply.
That's the message I get when I try to set DSCP/enable QoS globally (which I would normally use on a Cisco switch with Polycom phones).
I wont be back in my office for another day or so, but will post the output if a sh qos then.

Here are the command options on the latest firmware:
35xx-Stack-LabNet(config)# qos ?
map Configure the QoS maps.
trust Configure the System to basic mode and the trust state
. Use the no form to return untrusted state.
basic Set system QoS basic mode.
It does not look like an advanced mode is available in the feature set for the 3548 model.
That feature is available on the 5500 model.

I have the same issue. My 3548 is in - Qos: basic, Basic trust: vpt.
If I try to issue the command "(config)# qos advance ", the switch doesn't know that command. I get a wrong number of parameters or invalid range. My switch is running SW version 2.0.0.40.
What can I do from here?

I was able to create the vlan using the answers in the above replies. Only issue I have now is when I run the voice vlan enable command against a port it gives me the following error:
Configuration cannot be applied in the current port mode
Port config as follows:
interface range ethernet 1/e(1-48),2/e(1-48),3/e(1-48),4/e(1-48)
spanning-tree portfast
(port im working on is 4/e34)
Do I have to put the port into trunk mode? as the data vlan is 1 and the voice vlan is 1200
Thanks

Is voice VLAN enabled globally?
# voice vlan id "vlan-id"
The port should be in Trunk mode, or general mode. Without being in one of those modes the port can only participate in the one specific VLAN.

I changed the port to a trunk and get the following:
SWTWRLV2001# show interfaces switchport ethernet 4/e19
Port : 4/e19
Port Mode: Trunk
Gvrp Status: disabled
Ingress Filtering: true
Acceptable Frame Type: admitAll
Ingress UnTagged VLAN ( NATIVE ): 200

I have a Unify phone with a PC daisy chained off it. Both devices are getting an IP from VLAN 200.
I modified the OUI table to add the Unifty phone as below, but its still not getting assigned to the correct VLAN, any ideas?

After setting it to Trunk mode were you able to set the voice vlan enable? Can you post up the running config for us?

The config looks good to me. If you set the phone with a static address will it work? If so then you may need to visit the DHCP server settings. Where does the DHCP server reside?

Set the IP manually on the phone... no luck. Cant ping the IP etc. I'm thinking the port channel from the core to the dell stack is not passing on that vlan.
While I was typing this I found that vlan 1200 was not allowed on the port channel on the dell switch. The core now can ping the vlan. Still cant ping the phone from the switch, I will do some more testing... if anyone has some suggests let me know.

I set the phone's discovery mode to Manual VLAN and DHCP. Set the VLAN as 1200. Phone is now getting an IP from Vlan 1200 and the attached PC is getting an IP from VLAN 200. Question is I thought by adding the mac address to the oui table this process was meant to happen automatically?

Thanks for keeping us up to date. I am glad to hear you found a way to get it working. You are correct though, with the voice VLAN enabled it should detect the OUID and place the traffic on the voice VLAN.
Maybe try changing the ports to General mode instead of Trunk mode.
console(config-if)# switchport mode general
See if that changes the behavior at all.

set the port to general mode as below:
interface ethernet 4/e34
switchport mode general
switchport general pvid 200
switchport general allowed vlan add 200 untagged
voice vlan enable
Same thing phone doesn't pickup the correct VLAN I still have to manually set it up...

I found this document outlining enabling LLDP-MEd on the switch. This will help the switch communicate with the phone and identify it as a VOIP device.
en.community.dell.com/.../2587.powerconnect-35xx-lldp-med-configuration
I would look through it for some guidance. If it continues to not work, you may need to setup port mirroring and use wireshark to see if port is receiving the OUID from the phone.
