Security
SSL SSL support; encrypts all HTTP traffic, allowing secure access to the browser-based
management GUI in the switch
Security policy slider Three security levels: low, medium, and high (configurable using Cisco Configuration
Assistant only)
Low—For business environments where there is limited guest access; limited
number of devices are allowed per port
Medium—For business environments where security is important; only authorized
devices (by MAC address) are allowed on the company network
High—For business environments where security is crucial; only authorized devices
(by MAC address) and authenticated users (using IEEE 802.1x) are allowed on the
company network
Multicast
High-bandwidth video traffic is optimized so that it does not affect other applications
on the network.
Internet Group Management Protocol (IGMP) (v1, v2, and v3) snooping constrains
multicast traffic at Layer 2 by configuring Layer 2 LAN ports dynamically to forward
multicast traffic to only those ports that want to receive it
