3.9 Priority Setting
The priority setting of the switch can be set to “Disable” , “Port-Based” or “IEEE802.1p” .
The priority setting menus include the tree sub-menus:
„
Priority mode
„
Port-Based priority
„
Port Default priority
„
802.1p Priority class
3.9.1 Priority mode
The switch provided three priority modes: “Disable” , “Port-Based” or “IEEE802.1p” . The priority rule can be set to
“Weighted” or “Fixed” .
The switch classifies the ingress packets into four classes: “lowest” , “lower” , “higher” and “highest” . When priority rule
is configured as "weighted" , a 1,2,4,8 weighting is applied to forward these packets. When "fixed" is selected, all packets
with top priority egress for a switch port until that priority's queue is empty, then the packets with next lower priority.
Example: In case of port-based priority mode:
If "weighted" is configured and the priority classes of four switch ports a, b, c and d are configured as lowest, lower, higher
and highest respectively, when the packets entering from these four ports are queued at one egress port, the switch then
forwards 8 d's packets, 4 c's packets, 2 b's packets and one a's packet at a time.
If "fixed" is configured and the priority classes of four switch ports a, b, c and d are configured as lowest, lower, higher and
highest respectively, all d's packets are forwarded first, then c, b, a. The screen in
Figure 3-29 appears.
