also maintain quality for real-time applications like voice and video. Network traffic can be
optimized with the switch’s 802.1Q VLAN 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 voice over IP (VoIP) deployments, the Cisco SLM248P supports the IEEE 802.3af
standard for Power over Ethernet (PoE). This eliminates the need for additional power cables or a
nearby power outlet, thereby making installation simple and inexpensive and allowing networking
devices like cameras and wireless access points to be positioned in optimal locations such as
ceilings and walls - even outdoors.
Network security is an absolute requirement for any business, and preventing unauthorized access
to the company network is critical. The Cisco 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 switch’s MAC-based
filtering capability, which allows network access only to those devices or workstations that have
been authorized as identified by their MAC address. The many-to-one or one-to-one port mirroring
feature of the Cisco SLM248P enables you to monitor the type of traffic being transmitted on the
network.
The Cisco SLM248P includes features for quickly expanding 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 Cisco 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 breaks. The switch’s Spanning Tree Protocol (STP) support
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
that 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.
