● CiscoWorks network-management software provides management capabilities on a per-port
CiscoWorks Support
and per-switch basis, providing a common management interface for Cisco routers, switches,
and hubs.
● SNMPv1, v2c, and v3 and Telnet interface support delivers comprehensive in-band
management, and a CLI-based management console provides detailed out-of-band
management.
● The CiscoWorks LAN Management Solution supports the Cisco Catalyst 2960 Series.
Availability and Scalability
Superior Redundancy for
● IEEE 802.1x Voice-aware security disables the offending data VLAN when a violation is
Fault Backup
detected without affecting Voice VLAN on the same switch port
● IEEE 802.1x readiness check determines readiness of connected end hosts, before
configuring 802.1x on the switch.
● Cisco UplinkFast and BackboneFast technologies help ensure quick failover recovery,
enhancing overall network stability and reliability.
● IEEE 802.1w Rapid Spanning Tree Protocol provides rapid spanning-tree convergence
independent of spanning-tree timers and the benefit of distributed processing.
● Per-VLAN Rapid Spanning Tree Plus (PVRST+) allows rapid spanning-tree reconvergence on
a per-VLAN spanning-tree basis, without requiring the implementation of spanning-tree
instances.
● Command-switch redundancy enabled in Cisco Network Assistant software allows
designation of a backup command switch that takes over if the primary command switch fails.
● Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links
to be detected and disabled to avoid problems such as spanning-tree loops.
● Switch port autorecovery (errdisable) automatically attempts to re-enable a link that is
disabled because of a network error.
● Cisco Redundant Power System 2300 (RPS 2300) support provides superior internal power-
source redundancy for up to six Cisco networking devices, resulting in improved fault
tolerance and network uptime.
● Bandwidth aggregation up to 8 Gbps through Cisco Gigabit EtherChannel technology and up
to 800 Mbps through Cisco Fast EtherChannel technology enhances fault tolerance and offers
higher-speed aggregated bandwidth between switches and to routers and individual servers.
● Flex Links provides link redundancy with convergence time 100ms without requiring Spanning
Tree Protocol.
● VLAN Flex Links load balancing improves network throughput by utilizing both links for traffic
distribution for different VLANs.
● Link State Tracking provides Layer 2 redundancy in the network when used in conjunction
with server or programmable logic controller (PLC) network interface card (NIC) adapter
teaming.
● Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from
Integrated Cisco IOS
Software Features for
degrading overall systems performance.
Bandwidth Optimization
● IEEE 802.1d Spanning Tree Protocol support for redundant backbone connections and loop-
free networks simplifies network configuration and improves fault tolerance.
● PVST+ allows for Layer 2 load sharing on redundant links to efficiently use the extra capacity
inherent in a redundant design.
● IEEE 802.1s Multiple Spanning Tree Protocol allows a spanning-tree instance per VLAN,
enabling Layer 2 load sharing on redundant links.
● Egress committed rate (ECR) guarantee provides load balancing and redundancy.
● Local Proxy Address Resolution Protocol (ARP) works in conjunction with Private VLAN Edge
to minimize broadcasts and maximize available bandwidth.
● VLAN1 minimization allows VLAN1 to be disabled on any individual VLAN trunk link.
● VLAN Trunking Protocol (VTP) pruning limits bandwidth consumption on VTP trunks by
flooding broadcast traffic only on trunk links required to reach the destination devices.
● Internet Group Management Protocol (IGMP) version 3 snooping provides fast client joins and
leaves of multicast streams and limits bandwidth-intensive video traffic to only the requestors.
● IGMP filtering provides multicast authentication by filtering out no subscribers and limits the
number of concurrent multicast streams available per port.
● Multicast VLAN registration (MVR) continuously sends multicast streams in a multicast VLAN
while isolating e streams from subscriber VLANs for bandwidth and security reasons.
