QOS (Quality of Service)
The GSS-8T2SFP provides up to four internal transmit queues per port to support four different
traffic priorities. The high-priority traffic experiences less delay in the switch than that of lower
priority traffic under congested conditions. For sensitive traffic, minimizing the delay time can be
very important. The GSS-8T2SFP provides three types of QOS. It can assign packets to one of four
transmit queues according to Port-Based QOS, 802.1P QOS or MAC-Based QOS. Port-Based QOS
arranges packets into one of four transmit queues by priority id of 802.1Q VLAN tag set in 802.1Q
VLAN page (802.1Q Control Per Port Config). 802.1P QOS arranges packet in to one of four
transmit queues by priority of ingress packet with 802.1Q VLAN tag. MAC-Based QOS arranges
packets in to one of four transmit queues by priority of ingress packet with the priority being set in
the Address Management page.
The GSS-8T2SFP also provides a remap function. The GSS-8T2SFP always inserts the packets into
the Tx Queue by it’s priority ID when the QOS function is enabled. Switch administrators can
modify the Priority ID to Tx Queue ID Map. Switch administrators can also remap 802.1Q priority
levels to priority ID’s. The GSS-8T2SFP handles the packets transmitted by the Tx Que ue Weight
Setting when Weighted Round-Robin algorithm is selected and QOS functions are enabled.
