Benefit
• 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 scenarios 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 (CGMP) server functions enable a switch
to serve as the CGMP router for CGMP 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.
• All 9 RMON groups are supported through a SPAN port, which permits traffic
monitoring of a single port, a group of ports, or the entire stack from a single
network analyzer or RMON probe.
• Domain Name Services (DNS) provide IP address resolution with user-defined
device names.
• Trivial File Transfer Protocol (TFTP) reduces the cost of administering software
upgrades by downloading from a centralized location.
• Network Timing Protocol (NTP) provides an accurate and consistent timestamp
to all intranet switches.
• Multifunction LEDs per port for port status; half-duplex and full-duplex mode;
and 10BASE-T, 100BASE-TX, and 1000BASE-T indication as well as switch-level
status LEDs for system, redundant-power supply, and bandwidth utilization
provide a comprehensive and convenient visual management system.
• SPAN works across all the ports in a stack.
