Ease of use and
ease of deployment
• Cisco Device Manager is an embedded web-based software that allows the customer to
easily configure and troubleshoot the switch, eliminating the need for more complex
terminal emulation programs and CLI knowledge, and reducing the cost of deployment by
enabling less-skilled personnel to quickly and simply set up switches.
• Smartports offers a set of verified feature macros per connection type in an easy-to-apply
manner. With these macros, users can consistently and reliably configure essential
security, availability, quality of service, and manageability features recommended for Cisco
Business Ready Campus solutions with minimal effort and expertise.
• Autoconfiguration eases the deployment of switches in the network by automatically
configuring multiple switches across a network via a boot server.
• Autosensing on each Ethernet port] detects the speed of the attached device and
automatically configures the port for 10-, 100-, or 1000-Mbps operation, easing the
deployment of the switch in mixed 10, 100, and 1000BASE-T environments.
• Autonegotiating on all ports automatically selects half- or full-duplex transmission mode to
optimize bandwidth.
• Cisco VTP supports dynamic VLANs and dynamic trunk configuration across all switches.
• DTP enables dynamic trunk configuration across all ports in the switch.
• Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN
for easier network administration and troubleshooting.
• Dynamic Trunking Protocol (DTP) enables dynamic trunk configuration across all ports on
the switch.
• PAgP automates the creation of Cisco Fast EtherChannel or Gigabit EtherChannel groups,
enabling linking to another switch, router, or server.
• Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with
devices that conform to IEEE 802.3ad. This is similar to Cisco EtherChannel and PAgP.
• The default configuration stored in Flash ensures that the switch can be quickly connected
to the network and can pass traffic with minimal user intervention.
