Resiliency and high availability
• Multiple spanning tree protocol (STP) and IEEE 802.1s
Oers high link availability in multiple VLAN environments by allowing multiple spanning
trees; and 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; and oer support for trunking across stack
members
• Ring and chain stacking topology
Allows failure of a link or switch in a ring of stacked switches, while the remaining connected
switches continue operation
• SmartLink
Provides easy-to-congure link redundancy of active and standby links
Management
• SNMPv1, v2, and v3
Provide complete support of SNMP and an industry-standard management information base
(MIB) as well as private extensions; SNMPv3 supports increased security using encryption
• Out-of-band Ethernet management port
Enables management of a separate physical management network, keeping management
trac segmented from network data trac
Manageability
• Dual ash images
Provides independent primary and secondary operating system les for backup while
upgrading
• Friendly port names
Allows assignment of descriptive names to ports
• Find, x, and inform
Finds and xes common network problems automatically, and then informs the administrator
• Multiple conguration les
Are easily stored with a ash image
• Software updates
Are oered as free downloads from the Web
• Remote monitoring (RMON), extended RMON (XRMON), and sFlow
Provide advanced monitoring and reporting capabilities for statistics, history, alarms, and
events
• Troubleshooting
Accelerates network problem solving with ingress and egress port monitoring
• Unidirectional link detection (UDLD)
Monitors the link between two switches and blocks the ports on both ends of the link if the link
goes down at any point between the two devices
