QoS Setup
Total 4 prioritized queues are provided for Ethernet packets, denoted as
Queue0
(lowest priority),
Queue1
,
Queue2
and
Queue3
(highest priority). You may assign the different packet dropping ratio and service weight for different
queue. Refer Chapter “
ADVANCED FEATURES
” for more XL-HCW128C
QoS
mechanism details.
For example, according to the setting diagram we classify TCP/UDP packet with port ‘1234’ or ‘80’ (decimal) as the
highest priority packet goes to Queue3, port ‘23’ goes to Queue2 and port ‘161’ goes to Queue1. Queue3 will not
discard any packet (Drop Ratio 0%), and packets in Queue3 is transmitted 4 times faster than packets in Queue0
according to their ‘
Service Weight
’. Packets in Queue0/Queue1/Queue2 will be discarded according to their ‘
Drop
Ratio
’ in case of any congestion.
IGMP v2 Snooping Setup
Support IGMP V2/V1 snooping only. Shut it off if SNMP V3 is adopted in the network.
Tag VLAN Setup
Enable the 802.1Q Tag VLAN function and set up the values in field ‘
VID’
and ‘
Priority’
. VID range is 1~4095
and Priority is 0~7.
Regard port HCNA as the network trunk. Once Tag VLAN is enabled, by default port LAN1/HCNA is set to the
same VLAN; also port LAN2/HCNA is in the same VLAN. Port LAN1/LAN2 is not within the same VLAN if
assigned with different VID.
Take the following VLAN setting diagrams for example.
First example, just enable Tag VLAN in both Master and EP ‘
VLAN
’ settings,
