LLDP-MED (Media Endpoint Discovery)
defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure
network devices such as IP phones
IEEE 802.1AB Link Layer Discovery Protocol (LLDP)
is an automated device discovery protocol that provides easy mapping of network management applications
PoE and PoE+ allocations
support multiple methods (automatic, IEEE 802.3at dynamic, LLDP-MED fine grain, IEEE 802.3af device class, or user specified)
to allocate and manage PoE/PoE+ power for more efficient energy savings
Local MAC Authentication
assigns attributes such as VLAN and QoS using locally configured profile that can be a list of MAC prefixes
Resiliency and high availability
IEEE 802.1s Multiple Spanning Tree
provides high link availability in multiple VLAN environments by allowing multiple spanning trees; provides legacy support for
IEEE 802.1d and IEEE 802.1w
IEEE 802.3ad Link Aggregation Control Protocol (LACP) and HP port trunking
support up to 60 static, dynamic, or distributed trunks active across a stack, with each trunk having up to eight links (ports) per
static trunk; support trunking across stack members
Ring and chain stacking topology
allows failure of a link or switch in the ring of stacked switches, while the remaining connected switches continue operation
New SmartLink
provides easy-to-configure link redundancy of active and standby links
Management
SNMPv1, v2, and v3
provide complete support of SNMP; provide full support of industry-standard Management Information Base (MIB) plus private
extensions; SNMPv3 supports increased security using encryption
Out-of-band Ethernet management port
enables management over a separate physical management network, keeping management traffic segmented from network
data traffic
Manageability
Dual flash images
provides independent primary and secondary operating system files for backup while upgrading
Friendly port names
allow assignment of descriptive names to ports
Find-Fix-Inform
finds and fixes common network problems automatically, then informs administrator
Multiple configuration files
allow multiple configuration files to be stored to a flash image
Software updates
free downloads from the Web
RMON, XRMON, and sFlow
provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
Troubleshooting
ingress and egress port monitoring enable network problem solving
Uni-Directional Link Detection (UDLD)
monitors a link between two switches and blocks the ports on both ends of the link if the link goes down at any point between
