Data Sheet
●
Power over Ethernet: Cisco 300 Series Switches are available with up to 48 PoE ports of Fast
Ethernet or 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. Some models support both IEEE 802.3af PoE and IEEE 802.3at PoE+
while others support IEEE 802.3af PoE only.
●
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.
●
Networkwide Automatic Voice Deployment: Using a combination of CDP, LLDP-MED, Auto
Smartports, and VSDP (Voice Services Discovery Protocol
– a unique patent-pending Cisco protocol),
customers can deploy an end-to-end voice network dynamically. The switches in the network
automatically converge around a single voice VLAN and QoS parameters and then propagate them out
to the phones on the ports where they are discovered. 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:
◦
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.
◦
Dual Configuration files support: Allows configuring the device, validating that it is configured
correctly and then saving this configuration to become effective after reboot. Additionally, a mirror
configuration file, providing automatic back-up of the latest stable configuration file maximizes
network uptime.
◦
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.
◦
Additional management options: The switches can be fully managed using the Web GUI or using a
full command-line interface (CLI).
