[cisco-voip] Simple Home QoS

[Linsemier, Matthew]

Phillip,

This is a 7.x PIX feature.  The PIX501 only supports up to release 6.x
of PIXOS at this time (unless something has changed in the last month),
hence why I didn't mention it.  I am still waiting for Cisco to support
7.x on the PIX501 and PIX506.

Actually, you can do some simple priority queueing on the PIX.

Tad,

>From what I understand about the switch in the 7940 phone this is just
be a coincidence.  Any traffic that comes from the 10/100 PC port is
supposed to be marked down to CoS0, while it marks its own traffic CoS5
and
DSCP EF.  That being said, any voice traffic that you may have on your
PC
(such as a softphone) or another 7940 plugged into your switch will be
marked CoS0 when it enters the phone switch.  When it leaves the 10/100
SW
port, it will have these markings.  Your PIX just passes the traffic out
to
your DSL/Cable proider in a FIFO method.  Newer versions of the PIXOS
will
preserve QoS markings (Such as DSCP, not sure about
CoS) but won't do any queuing or traffic manipulation based on the
markings.
The only way to accomplish this is to put in a device such that supports
traffic matching and priority queuing.  You can accomplish this with a
Cisco
83x/87x series router, or even the newer Linksys routers have a manual
way
to prioritize your traffic.  You could look at something like Hawkings
HBB1
(http://www.hawkingtech.com) and put it outside of your PIX before your
DSL/Cable modem if you wanted something that was more automated.

HTH,

Matt

I was having a problem with my home QoS, especially when sending voice
packets out my network when other uploading services (email, file
transfers,
etc.) were occurring on my home network.  I am using a Pix 501, and it's
been well documented that Pix's have no QoS.  However, most QoS problems
are
easily blamed on your ISP.  

I remembered that the ethernet switch on a 7940 phone had some sort of
QoS
prioritization.  So...  I stuck a 7940 between my Pix and my switch.
Guess what?  My QoS problem feels 90% better.  I suppose an 870 router
properly programmed can do the same thing, but my "simple solution" sure
seems easier.  

Am I dreaming?  Any comments or caveats?
