Efficient Switch Operation
Cisco Catalyst 3850 Series Switches, designed and engineered by Cisco, provide optimum power-saving, EEE,
low-power operations for industry best-in-class power management and power consumption capabilities. The
Cisco Catalyst 3850 ports are capable of reduced power modes so that ports not in use can move into a lower
power utilization state. Other efficient switch operation features are:
●
Cisco Discovery Protocol Version 2 allows the Cisco Catalyst 3850 Series Switches to negotiate a more
granular power setting when connecting to a Cisco powered device such as IP phones or access points
than what is provided by IEEE classification.
●
Per-port power consumption command allows customers to specify maximum power setting on an
individual port. Per-port PoE power sensing measures actual power being drawn, enabling more intelligent
control of powered devices.
●
The PoE MIB provides proactive visibility into power usage and allows customers to set different power-
level thresholds.
Environmentally Responsible
Organizations may choose to turn off access point radios to reduce power consumption during off-peak hours.
The integrated wireless LAN controller avoids the deployment of additional devices in the network.
Network Management Tools
The Cisco Catalyst 3850 Series Switches offer both a superior CLI for detailed configuration and Cisco Prime
™
infrastructure for unified wired plus wireless management. Prime infrastructure provides day 0 and ongoing
provisioning, ongoing monitoring and maintenance, configuration templates, and device and user 360-degree
views and serves as the FNF collector for user traffic views using the Prime Assurance Manager module.

Advanced Security Features
Cisco Catalyst 3850 Series Switches support advanced security features including but not limited to:
●
Protection against attackers:
◦
Port security secures the access to an access or trunk port based on MAC address. It limits the number
of learned MAC addresses to deny MAC address flooding.
◦
DHCP snooping prevents malicious users from spoofing a DHCP server and sending out bogus
addresses. This feature is used by other primary security features to prevent a number of other attacks
such as ARP poisoning.
◦
Dynamic ARP inspection (DAI) helps ensure user integrity by preventing malicious users from exploiting
the insecure nature of ARP.
◦
IP source guard prevents a malicious user from spoofing or taking over another user’s IP address by
creating a binding table between the client’s IP and MAC address, port, and VLAN.
