Cisco SLM2008 8-Port Gigabit Smart Switch with PD and AC Power Administration Guide 1
Introduction
The Cisco SLM2008 8-port Gigabit Smart Switch with PD and AC Power allows
you to upgrade your existing network by replacing your current workgroup hub or
switch. At the same time, you can configure advanced features for security, QoS,
and Spanning Tree using its web-based configuration utility.
The Cisco SLM2008 switch not only allows you to upgrade to gigabit speeds but
also allows you to expand your network securely. The Gigabit Smart Switch with
PD have virtual LAN (VLAN) capabilities to restrict the flow of multicast and
broadcast traffic. Stations within a given VLAN can freely communicate using
either unicast or multicast addressing. Communication between different VLANs is
not possible.
Extensive QoS features make the solution ideal for real-time applications like Voice
and Video. The 4 priority queues together with the Weighted Round Robin and
Strict Priority scheduling techniques facilitate efficient coexistence of real-time
traffic with data traffic allowing them each to meet their QoS needs. Individual
users or applications can be prioritized above others using various Class of
Service options - by port, layer 2 priority (802.1p), and layer 3 priority (TOS or
DSCP). Intelligent broadcast and multicast storm controls minimize and contain the
effects of these types of traffic on regular traffic. IGMP Snooping limits
bandwidth-intensive video traffic to only the requestors without flooding all users.
Incoming traffic can be policed and outgoing traffic can be shaped allowing you to
control network access and traffic flow.
There are features that allow you to expand and grow your network of switches.
Link aggregation allows multiple high-bandwidth trunks between switches to be
setup. This also provides a level of reliability in that the system continues to
operate if one of the links breaks. Spanning Tree (STP) allow you to build a mesh of
switches increasing the availability of the system.
