Layer 3 Routing Support
The SGS-6340-20S4C4X enables the administrator to conveniently boost network
efficiency by configuring Layer 3 static routing manually, the RIP (Routing Information
Protocol) or OSPF (Open Shortest Path First) settings automatically. The RIP can
employ the hop count as a routing metric and prevent routing loops by implementing
a limit on the number of hops allowed in a path from the source to a destination. The
maximum number of hops allowed for the RIP is 15. The OSPF is an interior dynamic
routing protocol for autonomous system based on link-state. The protocol creates a link-
state database by exchanging link-states among Layer3 switches, and then uses the
Shortest Path First algorithm to generate a route table based on that database.
High Performance
The SGS-6340-20S4C4X boasts a high-performance switch architecture that is capable
of providing non-blocking switch fabric and wire-speed throughput as high as 56Gbps,
which greatly simplifies the tasks of upgrading the LAN for catering to increasing
bandwidth demands.
Abundant IPv6 Support
The SGS-6340-20S4C4X provides IPv6 management and enterprise-level secure
features such as SSH, ACL, WRR (Weighted Round Robin) and RADIUS
authentication. The SGS-6340-20S4C4X thus helps the enterprises to step in the IPv6
era with the lowest investment. In addition, you don’t need to replace the network
facilities when the IPv6 FTTx edge network is built.
Excellent and Secure Traffic Control
TheSGS-6340-20S4C4Xisloaded withpowerfultrafcmanagementandWRRfeatures
to enhance services offered by telecoms and enterprises. The WRR functionalities
include wire-speed Layer 4 traffic classifiers and bandwidth limitation which are
particularly useful for multi-tenant unit, multi-business unit, Telco, or network service
applications.TheACLpoliciessupportedcanclassifythetrafcbysource/destinationIP
addresses, source/destination MAC addresses, IP protocols, TCP/UDP, IP precedence,
timerangesandToS.Moreover,variouspoliciescanbeconductedtoforwardthetrafc.
The SGS-6340-20S4C4X also provides IEEE 802.1x port based access authentication,
which can be deployed with RADIUS, to ensure the port level security and block
illegal users. Thus, the SGS-6340-20S4C4X empowers ISP and enterprises to take full
advantage of the limited network resources and guarantees the best performance in
VoIP and video conferencing transmission.
Robust Layer 2 Features
The SGS-6340-20S4C4X can be programmed for basic switch management functions
such as port speed configuration, port aggregation, VLAN, Spanning Tree Protocol,
WRR, bandwidth control and IGMP snooping. It also supports 802.1Q tagged VLAN,
Q-in-Q, voice VLAN and GVRP Protocol. The VLAN groups allowed to be on the SGS-
6340-20S4C4X will be maximally up to 256. By supporting port aggregation, the SGS-
6340-20S4C4X allows the operation of a high-speed trunk combined with multiple ports.
It enables up to 128 groups for trunking with a maximum of 8 ports for each group.
Efficient Management
The SGS-6340-20S4C4X supports IP stacking function that helps network managers
to easily configure up to 24 switches in the same series via one single IP address
