Re: [Astlinux-users] VLAN's and 802.1p priority

[Kevin K. <Ast...@gt...>]

Thought I would jump in here on the 802.1P. 
 
802.1P is priority queuing at the MAC layer.  IEEE standard 802.1p is a part
of the IEEE standard 802.1D. 802.1Q is the IEEE standard for vlans and is
part of the IEEE standard 802.1D. There are many switches with 802.1P
without 802.1Q VLAN's.

Or how about allow the VLAN definition have an optional trailing :N

VLANS="eth0.20:5"
 
I assume "0" is the current AstLinux defined priority?
 
In my case, I have Layer 2 switches, and only 802.1p priority tags
are used.  (HP Procurve 1700 and 1800 series)
 
Is this the the current best way of handling priorities?

Lonnie,
 
  I was hoping that I could eventually figure out a way to set the
802.1p value for non-vlan interfaces (eth0, eth1, eth2) as well.
 
  For VLANs only, I like your way more!

Kristian,
 
You know immensely more about this stuff than I do, but it is my
understanding that 802.1p requires 802.1Q (VLAN) tagging.
