<div dir="ltr"><font face="tahoma" size="2">- I assume the phone will send out 802.1p/dscp markings</font></div>
<div dir="ltr"><font face="tahoma" size="2"> - if so you need to configure the switch to trust those markings</font></div>
<div dir="ltr"><font face="tahoma" size="2"> - if not you need to define a policy to match that traffic (based on the incoming port, ip, protocol or ...) and mark it yourself</font></div>
<div dir="ltr"><font face="tahoma" size="2">- you need to assign those markings to the (hw-)queues of your choice on the interface on the switches</font></div>
<div dir="ltr"><font face="tahoma" size="2">- you need to define LLQ on the routers to assign priority bandwidth to those packets/markings</font></div>

<div><span style="FONT-SIZE: 11pt; FONT-FAMILY: 'Calibri','sans-serif'">I have a Nortel BCM200 phone system w/ I2002 & I2004 phones. We are needing to configure QOS on the 3560Gs they have in place for their Nortel phones. They are currently complaining of
static on all the phone lines including their intercom system (thru the Nortel phone system). We have them Vlan'd out (voice/data) but not sure of the commands to enable the QOS on switch for the phones. Does anyone happen to have any incite as to what needs
to be done in order to enable the QOS for these phones? Any help would be appreciated.<br>
<br>
Thanks<br>
