ADVANCED FEATURES
QUALITY OF SERVICE (QoS)
Quality of Service determines the relative priority of different data packets, which in turn determines which packets should
receive preferential routing from a VIA switch. QoS is often used for the distribution of video and audio signals, including the
Dante® audio standard, to meet the signal's required timing constraints.
Disabled (default): Disables QoS-based routing. All traffic is treated equally.
Standard: Traffic priority is observed using a weighted algorithm to ensure timely delivery of high priority traffic and eventual
delivery of lower priority packets.
Dante Strict: Traffic priority is strictly observed, using Dante-specified weighting. Lower priority traffic may be dropped or
ignored to ensure delivery of Dante's high priority packets.
NOTE: remember that giving all data high priority is the same as treating all traffic equally.
For more information, please refer to Appendix 5: Quality of Service (QoS).
RAPID SPANNING TREE (RSTP)
Click the checkbox to Enable / Disable (default) Rapid Spanning Tree Protocol (RSTP)
Rapid Spanning Tree Protocol automatically detects Ethernet loops (two Cat5 cables between the same two switches where
the ports are on the same VLAN). Without RSTP on, networks with loops will have very poor performance.
RSTP should be enabled on all switches on the network and not be used in conjunction with EAPS Ring Protection.
The interaction between RSTP and the Ring Protect system may cause long network re-configuration times when the ring
topology is changed. For this reason, it is recommended that RSTP be used during setup and then disabled after verifying
there are no loops present.
Warning: Rapid Spanning Tree must be enabled on all switches to detect loops correctly. Network loops created through
unmanaged switches may not be detected correctly. Pathway's implementation of Rapid Spanning Tree Protocol should be
inter-operable with other switch manufacturer's implementations.
For more information, please refer to Appendix 4: EAPS & RSTP - Ring Protection.
