Supported Modules And Encapsulations - Juniper JUNOSE 11.0.X MULTICAST ROUTING Configuration Manual

Each port on the I/O module or IOA displayed in Figure 18 on page 162 has two
queues. These queues are further down the egress path than the queues found on
the line module and populated by the FC.
The low-priority queue is dedicated to packets that are received from the line module
queues that are dedicated to the physical ports. This queue blocks when full and
provides backpressure to the line module. This queue services unicast and multicast
traffic that is not using the hardware multicast packet replication feature.
The high-priority queue is dedicated to packets that are received from the line module
queue for port 8. This queue is serviced at a higher priority than the first queue, and
drops packets when full.

in JUNOSe Physical Layer Configuration Guide.

Supported Modules and Encapsulations

You can enable optimized multicast packet replication on port 8 of the following
high-density Ethernet modules:
When enabled, the optimized multicast packet replication feature defines the
encapsulation of the egress multicast packet. The following encapsulations are
supported:
NOTE: 802.3ad link aggregation group (LAG) bundles do not support optimized
multicast packet replication.
The optimized multicast packet replication feature also provides an interface over
which you can configure the following:
GE-8 I/O module (pairs with the GE-HDE line module)
ES2-S1 GE-8 IOA (pairs with the ES2 4G LM and the ES2 10G LM)
IPv6 over Gigabit Ethernet
IPv6 over VLAN
IPv6 over S-VLAN
IP MTU
