Chapter 34 ACL
IES-1248-51V User’s Guide

13 protocol <protocol>
14 {srcip <ip>/<mask>{|dstip <ip>/<mask>{|tos <stos> <etos> {|srcport
<sport> <eport> {|dstport <sport> <eport>}}}}}
The input values for these values have the following ranges.
<vid>: 1~4094
•<priority>: 1~7
<etype>: 0~65535
<protocol>: tcp|udp|ospf|igmp|ip|gre|icmp|<ptype>
<ptype>: 0~255
<mask>: 0~32
<tos>: 0~255
<port>: 0~65535
If you apply multiple profiles to a PVC, the IES-1248-51V 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-1248-51V checks Profile1 first. If the traffic is
VLAN ID 100, the IES-1248-51V follows the action in Profile1 and does not check
Profile2. You cannot assign profiles that have the same rule numbers to the same
PVC.
34.1.2 ACL Profile Actions
The IES-1248-51V 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-1248-51V can apply more than one action to a packet, unless you select
deny.
If you select the rvlan action, the IES-1248-51V 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-1248-51V drops the traffic because the new VLAN ID does not match
the VID of the PVC. This is illustrated in the following scenario.
