Znyx Networks bh5700 manual Match selectors, U Match Selectors

for a u16 match. In many cases, there is a field name that can be used for the match, eliminating the need to specify the offset.

Table 7.3: U Match Selectors

Note that specifying a tcp, udp, or icmp field does not automatically include a match for the appropriate IP protocol. To insure that only the desired packets are filtered, include a match for IP protocol as well as the port or type. For example:

u32 match ip protocol 6 0xff match tcp dst 8 0xffff

Or

u32 match ip protocol 17 FF match ip sport 20 0xffff

Thus far, tc has been used without zqosd. It is not sufficient to install software rules on the
