<acl>
•
ACL definition number
Specify the ACL definition number of the access control list where the packet pattern to
configure QoS conversion has been defined.
Use Mode Configuration mode (admin class)
Explanation Set IPv6 QoS per VLAN
For the input packets that match the "acl ipv6", "acl icmp", "acl tcp", or "acl udp"
definitions of the access control list which has been specified by <acl>, the QoS
processing is executed in the way as specified by <action>.
Caution
Note1.
If none of "acl ip6" definition exist on the access control list which has been specified by
<acl> or if the access control list specified by <acl> does not exist, the QoS processing is
not applied to those packets.
Note2.
If a queue is selected in <action> and if this queue has not been associated with the
priority by the "qos cosmap" command, the QoS processing is not executed.
Note 3.
This command is unavailable if the allowable upper limit for the device is exceeded.
The allowable upper limits are as follows.
• Upper limit based on "commands"
128 commands for the entire device.
Up to 128 commands can be set for the entire device, including the "vlan ip6qos
aclmap" and "lan ip6 dscp" commands.
1) "vlan ip6qos aclmap" command
A smaller VLAN ID has a higher priority among VLANs.
2) "lan ip6 dscp" command
A smaller lan definition number has a higher priority among lans.
If up to 128 of "vlan ip6qos aclmap" commands have been defined, the subsequent "lan
ip6 dscp"command will be no longer applied.
• Upper limit based on rule
128 rules for the entire device.
For the "vlan ip6qos aclmap" and "lan ip6 dscp" commands, the number of rules to be
used varies depending on the contents of the specified acl as shown below.
The number of rules for each ACL is as follows.
- For ACL to set TCP or UDP
Result of multiplication between the number of source ports and the number of
destination ports for TCP or UDP
- For ACL to set ICMP
Result of multiplication between the number of ICMP TYPEs and the number of
ICMP CODEs for ICMP
- For ACL not to set TCP, UDP, or ICMP

You can expand the upper limit to use "resource filter distribution" command and change
resource distribution.
