• vlan < vid > smac <mac>
• vlan < vid > dmac <mac>
• smac < mac > dmac <mac>
• vlan < vid > priority <priority>
• etype <etype>
• vlan <vid>
• smac <mac>
• dmac <mac>
• priority <priority>
• protocol <protocol>
• srcip <ip>/<mask> [dstip <ip>/<mask> [tos <tos> [srcport <sport>
<eport> [dstport <sport> <eport>]]]]
where
•
etype <etype> = Ethernet type (0~65535).
•
vlan <vid> = VLAN ID (1~4094).
•
smac <mac> = Source MAC address.
•
dmac <mac> = Destination MAC address.
•
priority <priority> = Priority (0 ~ 7)
•
protocol <protocol> = Protocol type: tcp, udp, ospf, igmp, ip, gre, icmp or user
specified IP protocol number <0 ~ 255>.
•
srcip <ip>/<mask> = Source IP address and subnet mask (0~32).
•
dstip <ip>/<mask> = Destination IP address and subnet mask (0~32).
•
tos <stos> <etos> = Sets the ToS (Type of Service) range between 0 and 255.
•
srcport <sport> <eport> = Source port range (0~65535).
•
dstport <sport> <eport> = Destination port range (0~65535).
The following guidelines apply to classifiers.
• You can apply one classifier for a protocol on a port’s PVC.
• You cannot create a classifier that contains matching criteria for layer 2 and layer 3 fields.
For example
switch acl profile set test protocol tcp vlan 15 deny is
not allowed as protocol type and VLAN do not belong to the same network layer.
• Each type of criteria can only be used once in a classifier. For example,
profile acl
set test protocol tcp protocol udp deny
is not allowed. For this example,
you need to create a separate classifier for each protocol and apply them to the same
PVC(s).
The following example creates an ACL rule example named
test for traffic from VLAN 10
with a priority level of 2. This rule limits the rate on the classified traffic to 1000 kbps and
changes the priority level to 7.
