IEEE 802.1w Rapid Spanning Tree Protocol provides a loop-free network and redundant 

links to the core network with rapid convergence. 

 

IEEE 802.1s Multiple Spanning Tree Protocol runs STP per VLAN base, providing L2 load 

sharing on redundant links. 

 

IEEE 802.3ad Link Aggregation Control Protocol (LACP) increases bandwidth by 

automatically aggregating several physical links together as a logical trunk and providing 

load balancing and fault tolerance for uplink connections. 

 

IGMP snooping prevents flooding of IP multicast traffic, and limits bandwidth intensive 

video traffic to only the subscribers. 

 

The DCRS-5950 series switch delivers high-performance, hardware based IP routing. 

 

RIP v1/v2 and OSPF v2 provide dynamic routing by exchanging routing information with 

other Layer 3 switches and routers. 

 

DVMRP, PIM-DM and PIM-SM Multicast Routing Protocols send IP multicast traffic from 

one subnet to another. 

 

VRRP prevents your system from failing by dynamically backing up multiple L3 switches 

for routing.   

 

8 queues per port enable differentiated management of up to 8 traffic types. 

 

Traffic is prioritized according to IEEE802.1p, DSCP, IP precedence and TCP/UDP port 

number, giving optimal performance to real-time applications such as voice and video.   

 

Bi-directional rate-limiting, per port or traffic class, preserves network bandwidth and 

allows full control of network resources.   

 

IEEE 802.1X port-based access control and MAC-based access control ensure all users 

are authorized before being granted access to the network. 

 

Access Control Lists (ACLs) can be used to restrict access to sensitive network resources 

by denying packets based on L2/L3/L4 headers information. 

 

Secure Shell (SSH) encrypts network management information via Telnet providing 

secure network management.
