Table 363 Define Basic ACL
Define Advanced ACL
The rules of the classification for advanced ACL are defined on the basis of the
attributes such as source and destination IP address, the TCP or UDP port number in
use and packet priority to process the data packets. The advanced ACL supports the
analysis of three types of packet priorities, ToS (Type of Service), IP and DSCP priorities.
You can use the following command to define advanced ACL.
Perform the following configuration in the corresponding view.
Table 364 Define Advanced ACL
Note that, the port1 and port2 in the above command specify the TCP or UDP ports
used by various high-layer applications. For some common port numbers, you can use
the mnemonic symbols as a shortcut. For example, “bgp” can represent the TCP
number 179 used by BGP.
Define Layer-2 ACL
The rules of Layer-2 ACL are defined on the basis of the Layer-2 information such as
source MAC address, source VLAN ID, Layer-2 protocol type, Layer-2 packet format
and destination MAC address.
You can use the following command to define the numbered Layer-2 ACL.
Perform the following configuration in corresponding view.
