QoS
When an ACL rule is referenced in a QoS policy,
the action defined in the ACL rule (deny or
permit ) does not work. Instead, the action on the
packets that match the ACL rule is determined by
the traffic behavior defined in the QoS policy.
ONU ports support packet filtering based on
source MAC address, destination MAC address,
Ethernet type, VLAN ID, source IP address,
destination IP address, source TCP port, and
source UDP port only.
Source MAC address-based packet filtering on an
ONU port works only on the uplink direction and
supports a maximum of 32 ACL rules.
Destination MAC address-based packet filtering
on an ONU port works on both uplink and
downlink directions and supports a maximum of
32 ACL rules.
Ethernet type-based packet filtering on an ONU
port supports a maximum of 30 ACL rules in the
case of single-direction configuration and a
maximum of 16 ACL rules for each direction when
configured for both uplink and downlink directions.
VLAN ID-based packet filtering on an ONU port
supports a maximum of 6 ACL rules for the uplink
direction and a maximum 8 ACL rules for the
downlink direction.
Source/destination IP address-based packet
filtering on an ONU port supports a maximum of
24 ACL rules in the case of single-direction
configuration and a maximum of 16 ACL rules for
each direction when configured for both uplink
and downlink directions.
Source TCP/UDP port-based packet filtering
supports a maximum of 24 ACL rules in the case
of single-direction configuration and a maximum
of 32 ACL rules when configured for both uplink
and downlink directions.
