using a command-line interface (CLI), Cisco Textview will be available for those who prefer to use text-based
configuration.* Together, these features reduce the time your staff must devote to network deployment,
management, and troubleshooting.
*Cisco Discovery Protocol, Smartports, and Textview will be available in the next firmware release.
Strong security: The Cisco 300 Series Switches provide a high level of security and give you fine-grained
●
control to safeguard your network from unauthorized users. Advanced security features include:
◦
◦
◦
◦
Power over Ethernet: Cisco 300 Series Switches are available with up to 48 PoE ports of Fast Ethernet or
●
28 PoE ports of Gigabit Ethernet connectivity. This capability simplifies advanced technology deployments
such as IP telephony, wireless, and IP surveillance by allowing you to connect and power network endpoints
over a single Ethernet cable. With no need to install separate power supplies for IP phones or wireless
access points, you can take advantage of advanced communications technologies more quickly, and at a
lower cost.
IP telephony support: Cisco 300 Series Switches include embedded QoS intelligence to prioritize delay-
●
sensitive services such as voice and video, simplify unified communications deployments, and help ensure
consistent network performance for all services. For example, automated voice VLAN capabilities let you plug
any IP phone (including third-party phones) into your IP telephony network and receive an immediate dial
tone. The switch automatically configures the device with the right VLAN and QoS parameters to prioritize
voice traffic.
Advanced network management capabilities: As managed switches, the Cisco 300 Series lets you use
●
a variety of advanced features to control traffic over your network. Features include:
◦
◦
◦
◦
Optimal energy efficiency: Cisco 300 Series Switches are designed with a variety of power-saving features
●
across all models, providing the industry's broadest portfolio of "green" switches. These switches optimize

Embedded security to protect management data traveling to and from the switch and encrypt network
communications
Extensive access control lists (ACLs) to restrict sensitive portions of the network from unauthorized users
and guard against network attacks
Guest virtual LANs (VLANs) to let you provide Internet connectivity to nonemployee users while isolating
critical business services from guest traffic
Support for advanced network security applications such as IEEE 802.1X port security to tightly limit
access to specific segments of your network
Static routing/Layer 3 switching between VLANs: This capability allows you to segment your network into
separate workgroups and communicate across VLANs without degrading application performance. As a
result, you can manage internal routing with your switches and dedicate your router to external traffic and
security, helping your network run more efficiently.
IPv6 support: As the IP network addressing scheme evolves to accommodate more devices, you can make
sure that your network is ready. The Cisco 300 Series provides native support for IPv6, the newest version of
the Internet Protocol, as well as the previous IPv4 standard. As a result, you will be able to move up to the
next generation of networking applications and operating systems without an extensive equipment upgrade.
Dual image support: With the ability to maintain dual images of your switches, you can perform software
upgrades without having to take the network offline and without worrying about an outage during an upgrade.
Remote management: Using Simple Network Management Protocol (SNMP), you can set up and manage
all switches and other Cisco devices in your network remotely, instead of having to directly connect to
them.
