– 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 802.1p priority only;
• DSCP preferred–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 preferred–distribute packets into queues based on IP diffserv and 802.1р priorities, if both
priorities are present in the packet, 802.1p priority is used for queuing purposes;
– Remapping 802.1p priority–remap 802.1р priorities for untagged packets. Thus, a new value may be
assigned for each priority received in VLAN packet;
– ingress limit mode–restriction mode for traffic coming to the port:
• off–no restriction;
• all–restrict all traffic;
• mult_flood_broad–multicast, broadcast, and flooded unicast traffic will be restricted;
• mult_broad–multicast and broadcast traffic will be restricted;
• broad–only broadcast traffic will be restricted.
– ingress rate prio 0 (kbps)–bandwidth restriction for incoming port traffic, priority 0. Permitted values–from
70 to 250000kbps;
– ingress rate prio 1–bandwidth restriction for incoming port traffic, priority 1. You can double the bandwidth
(prev prio *2) of priority 0, or leave it unchanged (same as prev prio);
– ingress rate prio 2–bandwidth restriction for incoming port traffic, priority 2. You can double the bandwidth
(prev prio *2) of priority 1, or leave it unchanged (same as prev prio);
– ingress rate prio 3–bandwidth restriction for incoming port traffic, priority 3. You can double the bandwidth
(prev prio *2) of priority 2, or leave it unchanged (same as prev prio);
– Egress limit on–enable the bandwidth restriction for outgoing port traffic;
– Egress rate limit–bandwidth restriction for outgoing port traffic. Permitted values–from 70 to 250000kbps.
– 802.1p priorities mapping–allows to distribute packets into queues depending on the 802.1р priority:
• 802.1р–802.1р priority value;
• Queue–outgoing queue number.
– IP diffserv priorities mapping–allows to distribute packets into queues depending on the IP diffserv priority
(for basic diffserv values, see Table 7):
• diffserv–IP diffserv priority value;
• Queue–outgoing queue number.
