KE devices on a network which makes fine tuning the bandwidth, data
throughput and video quality easier. Stackable switches can be configured to
direct the KE transmissions between many units more specifically and
effectively. Standalone switches provide the same configuration features as
Stackable switches but they must be set individually.
Stackable switches provide an easy way to manage multiple switches, as one
unit. For example, instead of configuring, managing, and troubleshooting 6 28-
port switches individually, you can manage the six as if they are a single unit
using Stackable Switches. The six switches (168 ports) function as a single
switch and are managed from one web or GUI interface.
What Stackable Switches Can do:
1. Create a link aggregation group with one port in one unit of the stack and
another port of that group in another switch in the stack.
2. Select a port on one switch in the stack and mirror the traffic to a switch
port on another unit of the stack; thus copy the configuration to direct
traffic more effectively between KE devices.
3. Apply custom ACL security settings to any port on any switch in the stack.
4. Stackable switches can be setup in a ring configuration, so that if a port or
cable fails, the stack automatically routes around the failure, at
microsecond speeds. Stackable Switches also allow you to add and remove
stack “members” which are automatically updated and recognized as such.
Switch Specifications
The following specifications are recommended when choosing a layer 2 or
layer 3 switch:
 1000Mbps Gigabit Ethernet switches (1000Mbps or faster Ethernet ports)

High bandwidth between switches, if possible using Fibre Channel
 Layer 3 switches that efficiently processes IGMP queries
 IGMP Snooping v2 or v3

Flow Control Functions
 Throughput of: Full Duplex, 1Gbps up- and down- stream speeds per port
 Performance of their most onerous tasks (e.g. IGMP snooping) with
multiple dedicated processors (ASICS)

Use the same switch make and model throughout each subnet
