Values
Names of forwarding classes assigned to queue numbers. The following are the default
forwarding classes:
best-effort —Provides no special CoS handling of packets. Loss priority is typically not
carried in a CoS value.
expedited-forwarding
end-to-end service.
assured-forwarding
Excess packets are dropped.
network-control —Packets can be delayed but not dropped.
EX8200 switches have the following additional default forwarding classes:
mcast-be —Provides no special CoS handling of packets.
—Provides low loss, low delay, low jitter, assured bandwidth, and end-to-end
mcast-ef
service.
—Provides high assurance for packets within the specified service profile. Excess
mcast-af
packets are dropped.
Queue number corresponding to the forwarding class name. The default forwarding classes
are assigned as follows:
—0
best-effort
expedited-forwarding
assured-forwarding
—7
network-control
—2
mcast-be
—4
mcast-ef
mcast-af —6
(EX8200 switches only) Fabric priority for the forwarding class, either
priority determines the priority of packets ingressing the switch fabric.
