D-Link xStack Switch Series: Meeting the Need at the Edge of the Network 9
D-Link Systems, Inc.

IGMP snooping
xStack switches feature IP Multicast support by examining (‘snooping’) all Internet Group
Multicast Protocol (IGMP) traffic in hardware at line rate, and pruning unwanted data streams
from affecting network or end-station performance. Network performance will become more
efficient and load processing can be reduced dramatically.
Multicast benefits server load
Multiple Spanning Tree protocol groups
The xStack Switch family supports multiple Spanning Tree Groups, either in a single
standalone switch or distributed across a stack. Spanning Tree Groups provide multiple data
paths which can be used for load-balancing, redundancy, and to prevent loops in a network. The
switch architecture also supports IEEE 802.1s and 802.1w.
High Availability Uplinks
The xStack Series supports redundant copper and/or fiber Gigabit Ethernet uplinks and
redundant 10-Gigabit Ethernet uplinks for not only the highest uplink capacity at the edge, but
also the greatest redundancy. If any single uplink port is not available, a xStack switch can
automatically failover to the redundant port for maximum resiliency and connectivity. The result
is true high availability--the user stays connected to the network and remains productive.
Extensive Network Management Functions
xStack Switches support a variety of network management options including: console CLI,
Telnet configuration, Web-based and SNMP v.1/v.2c/v.3 management, RMON monitoring,
TFTP firmware upgrade, Port Mirroring for troubleshooting, BootP, and DHCP IP assignment.
The xStack also supports a variety of advanced traffic management options including: 802.1x,
Bandwidth Control, Broadcast Storm Prevention, and support for IGMP v.1, v.2 snooping.
