Subject: Re: tos values
I couldn't find it, but I did figure it
it works like this..
say the ip precedece is 5 and you want to conver it to ToS
ToS uses 8 bits in hex ie 00000000 split into 2 parts 0000 0000
ip precedence is 5 ..so that would be the fifth bit in ToS which would
equal 0001 0000
beaking down the ToS bits 0 0 0 0 0 0 0 0
E C A 8 4 2
1
there is not a match to worry about for the 8th bit, as ip precedence
only
goes to 7
R7(config)#access-list 107 permit ip any any precedence ?
<0-7> Precedence value
critical Match packets with critical precedence (5)
flash Match packets with flash precedence (3)
flash-override Match packets with flash override precedence (4)
immediate Match packets with immediate precedence (2)
internet Match packets with internetwork control precedence (6)
network Match packets with network control precedence (7)
priority Match packets with priority precedence (1)
routine Match packets with routine precedence (0)
going back to ip precedence of 5 would equal 0001 0000 in ToS
therefore the ToS of A0 would equal an ip precendece of 5
another example... ip precedence of 7 would equal ToS E0
7 = 0100 0000
