Cisco SLM248P-G5 Manuale Utente

The new Linksys Business Series Smart Ethernet Switches are cost-effective switching solutions 

ideal for small businesses, the network edge, or workgroups within larger organizations. These 

easy-to-install, high-speed switches offer many of the same Quality of Service and Security 

features found in more expensive full Layer 2 managed switches but without their complexity. 

The SLM248P offers forty-eight (48) 10/100 Copper ports with two (2) shared Gigabit copper 

or optical (SFP) uplink interfaces for connecting the switch to the core network. The SLM248P’s 

simplified user interface is an intuitive management tool enabling you to quickly utilize the 

comprehensive feature-set of the switch, resulting in a better optimized network.
Quality of Service—The SLM248P includes numerous QoS features to ensure that traffic is 

prioritized properly to deliver the best possible user experience for real time applications like voice 

and video or bandwidth intensive graphic/video file uploads or downloads. With its IGMP Snooping 

feature, the SLM248P limits IP multicast traffic (real time presentations, videoconferences, on-line 

gaming) to only the ports that have requested it enabling the rest of the network to operate at peak 

efficiency. Additional QoS capabilities like IEEE 802.1p Priority Tagging, DSCP (Differentiated Services 

Code Point), and 4 hardware queues also maintain quality for real-time applications like voice and 

video. Network traffic can be optimized with the switch’s 802.1Q VLAN (Virtual LAN) support which 

enables you to quickly segregate network traffic by department or workgroup. VLANs also provide an 

additional layer of security by keeping sensitive data separated from other workgroups on the network. 
For Wireless or VoIP deployments, the SLM248P supports the IEEE802.3af standard for Power over 

Ethernet (PoE). This eliminates the need for additional power cables and the need for a nearby power 

outlet, thereby making installation simple and inexpensive, allowing networking devices like cameras 

and Wireless Access Points to be positioned in optimal locations like in ceilings and walls—even outdoors.
Network Security is an absolute requirement for any business and preventing unauthorized access 

to the company network is business-critical. The SLM248P secures the network through 802.1X port 

authentication which prompts end-users to provide their username and password before they are 

permitted to pass data. User access can also be controlled through the SLM248P’s MAC-Based Filtering 

capability which allows network access only to those devices or workstations that have been authorized 

as identified by their MAC (Media Access Control) address. The Many-to-One or One-to-One Port Mirroring 

feature of the SLM248P enables you to monitor the type of traffic being transmitted on the network. 
Quick, foolproof network expansion—The SLM248P includes features for quickly expanding and growing 

your network. To substantially increase network throughput speeds, especially useful for companies whose 

employees are routinely backing up their hard drives to a company server or storage platform, the SLM248P 

supports Link Aggregation which allows multiple high-bandwidth trunks between switches to be set up. Link 

Aggregation also provides a level of availability and redundancy as traffic will continue to flow even if one of 

the network links break. The SLM248P’s Spanning Tree Protocol support (STP) and Storm Control features help to 

control planned or inadvertent cable loops when switches are connected to one another. These loops can cause 

broadcast or multicast storms in the network and severely limit its performance. With these features, you can 

confidently build a mesh of switches and quickly expand your network to support your growing workforce.
