QoS and bandwidth control
In the 'QoS and bandwidth control' section, you may configure Quality of Service functions.
VLAN priority (default)
— 802.1р priority assigned to untagged packets, received by this port. If
802.1р
or
IP Diffserv
is already assigned to the packet, this setting will not be used ('default vlan
priority' will not be applied to packets containing IP header, when one of the QoS modes is in use:
DSCP only, DSCP preferred, 802.1p preferred
).
QoS mode
— QoS operation mode:
–
DSCP only
— distribute packets into queues based on IP Diffserv priority only.
–
802.1p
only — distribute packets into queues based on 802.1р priority only.
–
DSCP, 802.1p
— distribute packets into queues based on IP Diffserv and 802.1р priorities,
if both priorities are present in the packet, IP Diffserv priority is used for queuing purposes.
–
802.1p, DSCP
— distribute packets into queues based on IP Diffserv and 802.1р priorities,
if both priorities are present in the packet, 802.1р priority is used for queuing purposes.
Remap 802.1p priorities
— remap 802.1р priorities for untagged packets. Thus, a new value may
be assigned for each priority received in VLAN packet.
Ingress packets limit mode
— restriction mode for traffic coming to the port.
–
Off
— no restriction.
–
All packets
— restrict all traffic.
–
BroadMultFlood
— multicast, broadcast, and flooded unicast traffic will be restricted.
–
BroadMult
— multicast and broadcast traffic will be restricted.
–
Broad
— only broadcast traffic will be restricted.
Speed limit for ingress queued packets 0
— bandwidth restriction for traffic incoming to a queue 0
port. Permitted values — from 70 to 250000kbps.
Speed limit for ingress queued packets 1
— bandwidth restriction for traffic incoming to a queue 1
port. You can double the bandwidth (prev prio *2) of priority 0, or leave it unchanged (same as
prev prio).
