Case 2: ACL for IP address
For IP address ACL, it can filter on source IP address, destination IP address, or both. It also supports to
set IP range ACL. When it filters on both IP address, packets coincident with both rules will take effect. In
other words, it does not do filter if it only coincident with one rule.
If user want to filter only one directional IP address, the other IP address just set to all zero. It means
don’t care portion. Besides IP address, it also supports Protocol for filter additionally. (TCP=6, UDP=17,
etc.) Certain Protocol under these IP addresses will take effect. If user doesn’t care Protocol, he can just
set to zero value. The detail testing, please refer to MAC ACL above.
Case 3: ACL for L4 Port
For Layer4 port ACL, it can filter on (1) source IP address, (2) source L4 port, (3) destination IP address,
(4) destination L4 port, and (5) UDP or TCP Protocol. User can select to filter on (1)~(4) for all or some
specific values, but it should select exact one Protocol from UDP or TCP.
When it filters on both directional IP address and L4 port, packets coincident with both rules will take
effect. In other words, it does not do filter if it only coincident with one rule.
If user wants to filter only one directional IP address or L4 port, the other IP address and L4 port just set
to all zero. It means don’t care portion. The detail testing, please refer to MAC ACL above.
Case 4: ACL for ToS
For Type of Service (ToS) ACL, it can filter on (1) source IP address with ToS type , or (2) destination IP
address with ToS type, or (3) both, or (4) both not (just filter ToS). When it filters on both IP address,
packets coincident with both rules will take effect. In other words, it does not do filter if it only coincident
with one rule.
If user want to filter only one directional IP address, the other IP address just set to all zero. It means
don’t care portion. The detail testing, please refer to case 1 MAC ACL above.
Valid Values: Precedence: 0~7, ToS: 0~15, DSCP: 0~63
This value (7) is reserved and set to 0.
Ex: Pre (001) means 1
Pre (100) means 4
ToS (00010) means 1
ToS (10000) means 8
DSCP (000001) means 1
DSCP (100000) means 32
