Hi Hunt and Chen
I went through this email only now (I know I'm a little late!) and suddenly
it struct me.......
They talk of priority traffic, were they not perhaps looking for priority
precendence
<0-7> Precedence value
critical Set critical precedence (5)
flash Set flash precedence (3)
flash-override Set flash override precedence (4)
immediate Set immediate precedence (2)
internet Set internetwork control precedence (6)
network Set network control precedence (7)
priority Set priority precedence (1)
routine Set routine precedence (0)
<cr>
Or how are we to determine what precedence priority traffic really is? Yes,
precedence 5 but what about 4?
Edward
