Feature Benefit
• Trusted boundary provides the ability to trust the QoS priority settings if an IP phone is present and to
disable the trust setting in the event that the IP phone is removed, thereby preventing a malicious user from
overriding prioritization policies in the network.
• Multilevel security on console access prevents unauthorized users from altering the switch configuration.
• The user-selectable address-learning mode simplifies configuration and enhances security.
• Bridge protocol data unit (BPDU) guard shuts down Spanning Tree PortFast-enabled interfaces when
BPDUs are received to avoid accidental topology loops.
• Spanning Tree Root Guard (STRG) prevents edge devices not in the network administrator’s control from
becoming Spanning Tree Protocol root nodes.
• IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of
concurrent multicast streams available per port.
• Dynamic VLAN assignment is supported through implementation of VLAN Membership Policy Server
client capability to provide flexibility in assigning ports to VLANs. Dynamic VLAN facilitates the fast
assignment of IP addresses.
• Cisco CMS Software security wizards ease the deployment of security features for restricting user access to a
server as well as to a portion or all of the network.
• 1000 access control entries (ACEs) are supported.
MANAGEABILITY
Superior Manageability
• Cisco IOS CLI support provides common user interface and command set with all Cisco routers and Cisco
Catalyst desktop switches.
• Service Assurance Agent support facilitates service-level management throughout the LAN.
• Switching Database Manager templates for access, routing, and VLAN deployment allow the administrator
to easily maximize memory allocation to the desired features based on deployment-specific requirements.
• VLAN trunks can be created from any port, using either standards-based 802.1Q tagging or the Cisco Inter-
Switch Link (ISL) VLAN architecture.
• Up to 1005 VLANs per switch or stack and up to 128 Spanning-Tree instances per switch are supported.
• 4000 VLAN IDs are supported.
• Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN for easier
administration and troubleshooting.
• Cisco VLAN Trunking Protocol (VTP) supports dynamic VLANs and dynamic trunk configuration across
all switches.
• Cisco Group Management Protocol server functions allow a switch to serve as the Cisco Group Management
Protocol router for client switches. EMI is required.
• IGMP snooping provides fast client joins and leaves of multicast streams and limits bandwidth-intensive
video traffic to only the requestors.
• Remote Switch Port Analyzer (RSPAN) allows administrators to remotely monitor ports in a Layer 2 switch
network from any other switch in the same network.
• For enhanced traffic management, monitoring, and analysis, the Embedded Remote Monitoring (RMON)
software agent supports 4 RMON groups (history, statistics, alarms, and events).
• Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from source to
destination.
