Advanced Quality of
Service (QoS)
Service (QoS)
Priority queuing ensures high-priority traffic gets delivered efficiently, even during congestion
from high traffic bursts. Companies implementing network telephony or video conferencing, for
example, need to be able to prioritize such voice and video traffic and other real-time applications
over less latency-sensitive traffic to ensure reliability and quality. The ability to prioritize traffic
ensures quality of latency-sensitive services and applications despite increasing traffic loads. The
ProSafe Gigabit Stackable Smart Switches provide an extensive set of QoS features:
• 802.1p-based prioritization
• Layer 3-based (DSCP) prioritization
• Rate-limiting
• TCP/UDP-based prioritization

“Smart” Management Features
Manage all ProSafe Gigabit Stackable Smart Switches as though they are one unit from an
easy-to-use Web console that can be used to configure all features, as well as monitor and
trouble-shoot. These switches also have SNMP (v1, 2 and 3) to collect and track data to monitor
the network health, as well as manage devices, and more easily enforce critical IT controls and
policies. SNMP v2c is most commonly deployed, as it provides better reporting capabilities than
SNMP v1. Companies interested in more robust security may opt for SNMP v3, which provides
data encryption.
All ProSafe Gigabit Stackable Smart Switches provide world-class reliability with a NETGEAR
Lifetime Warranty and optional ProSupport Maintenance Packages. These switches are optimized
for ProSafe Network Management Software (NMS100) and works with other SNMP-based
management software.
Like all NETGEAR ProSafe Smart Switches, the GS724TS and GS748TS are backed by the NETGEAR
ProSafe Lifetime Warranty
