Chapter 31 ACL
• <tos>: 0~255
• <port>: 0~65535
If you apply multiple profiles to a PVC, the IES-612-51A checks the profiles by rule number.
The lower the rule number, the higher the priority the rule (and profile) has. For example, there
are two ACL profiles assigned to a PVC. Profile1 is for VLAN ID 100 (rule number 9) traffic,
and Profile2 is for IEEE 802.1p priority 0 traffic (rule number 12). The IES-612-51A checks
Profile1 first. If the traffic is VLAN ID 100, the IES-612-51A follows the action in Profile1
and does not check Profile2. You cannot assign profiles that have the same rule numbers to the
same PVC.

31.1.2 ACL Profile Actions

The IES-612-51A can perform the following actions after it classifies upstream traffic.
• rate <rate>: change the rate to the specified value (1~65535 kbps)
• rvlan <rvlan>: change the VLAN ID to the specified value (1~4094)
• rpri <rpri>: change the IEEE 802.1p priority to the specified value (0~7)
• deny: do not forward the packet
The IES-612-51A can apply more than one action to a packet, unless you select deny.
If you select the rvlan action, the IES-612-51A replaces the VLAN ID before it compares the
VLAN ID of the packet to the VID of the PVC. As a result, it is suggested that you replace
VLAN ID on super channels, not normal PVC, since super channels accept any tagged traffic.
If you replace the VLAN ID for a normal PVC, the IES-612-51A drops the traffic because the
new VLAN ID does not match the VID of the PVC. This is illustrated in the following
scenario.
There is a normal PVC, and its PVID is 900. You create an ACL rule to replace the VLAN ID
with 901. Initially, the traffic for the PVC belongs to VLAN 900. Then, the IES-612-51A
checks the ACL rule and changes the traffic to VLAN 901. When the IES-612-51A finally
compares the VLAN ID of the traffic (901) to the VID of the PVC (900), the IES-612-51A
drops the packets because they do not match.
