Now on a router or switch, you can match traffic by matching a DHCP value.
So you could match if as an example and then do something with the traffic.
So here's my genius three rather.
And I can go to global configuration mode.
And use the command class map.
And I can either do a match all or a match any match all means all the statements have to be true when
matching match any means any one of them need to be true.
And as per this example, we could match VoIP or whatever name we decide.
And then we can say match and notice.
You can match on many values.
But as an example, we could match IP, DHCP, DHCP values or in the range 0 to 63.
There are eight binary bits.
So to to the power of eight is 64 in the range 0 to 63.
Here are the well known values.
Notice af 11.
So af one one or af 11.
AF one two.
So notice af12.
He has a 41 so af for one.
Here are the class selector values.
So as an example, cloth selector three.
Notice those binary bits equate to three.
And here we have expedited forwarding.
Notice what the binary is set to.
So if we set that to F and then do a show run.
Notice it shows up as that in the running config, but we could also use the command match IP DSP 46
because 46 is the same as F.
Is it a tomato or is it a tomato?
It's the same thing.
