z  DCRS-7604 supports up to 13 *10G ports, 188 (48×3+44) Gigabit ports and 188 10/100 

ports,  

z  DCRS-7608 supports up to 32 *10G ports or 384 (48×8) Gigabit ports, providing flexibility 

and high port density.   

z  10G modules support 4 ports for downlink to L3 Gigabit distribution layer switches or L2 

Gigabit switches, aggregating them to the core layer, and preventing port bottlenecks in 
Gigabit switches. Furthermore, the optional 10Gigabit Ethernet XFP transceivers can be 
chosen for different distance fiber uplinks. 

z  Backup Master ensures the availability of a master controller for network control at any 

time. 

z  Firmware & configuration are automatically upgraded from master to slave units for 

management simplicity. 

*Intensive protocol support is included for MPLS, MPLS-VPN, MPLS-TE ensuring future investment protection. 

 

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

links to the core network with rapid convergence. 

z  IEEE 802.1s Multiple Spanning Tree Protocol runs STP per VLAN base, providing Layer 2 

load sharing on redundant links. 

z  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. 

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

video traffic to only the subscribers. 

 

z  The DCRS-7600 series delivers high-performance hardware based IP routing. 
z  RIP and OSPF provide dynamic routing by exchanging routing information with other Layer 

3 switches or routers. 

z  DVMRP, PIM-DM Multicast Routing Protocols send IP multicast traffic from one subnet to 

another. 

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

for routing. 

 

z  8 egress queues per port enable differentiated management of up to 8 traffic types. 
z  Traffic is prioritized according to 802.1p, DSCP, IP precedence and TCP/UDP port number, 

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

z  Bidirectional rate limiting, per port or traffic class, preserves network bandwidth and allows 

full control of network resources.
