It is taking 8 bits, hence the value. The last two bits are for ECN which is set 00
EF = 101110, now append that ECN 10111000 = B8 = 184 With regards Kings On Tue, May 15, 2012 at 6:13 AM, Eugene Pefti <[email protected]>wrote: > Hello folks,**** > > I ran into different ways of setting DSCP values.**** > > My two QoS relating tasks ask to match for VoIP traffic with DSCP value > equals to EF.**** > > Then the verifications use something that I have no idea how to understand > and cross-check with Cisco documentation.**** > > ** ** > > E.g.
