Cisco SLM248G Switch SLM248G Manual Do Utilizador

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 SLM248G 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 SLM248G’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 SLM248G 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 SLM248G 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.
Network Security is an absolute requirement for any business and preventing unauthorized 

access to the company network is business-critical. The SLM248G 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 SLM248G’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 SLM248G enables you to monitor the type of traffic 

being transmitted on the network. 
Quick, foolproof network expansion – The SLM248G 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 SLM248G 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 SLM248G’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.
