●
Bidirectional data support on the Switched Port Analyzer (SPAN) port allows the Cisco
intrusion detection system (IDS) to take action when an intruder is detected.
●
TACACS+ and RADIUS authentication facilitates centralized control of the switch and
restricts unauthorized users from altering the configuration.
●
Multilevel security on console access prevents unauthorized users from altering the switch
configuration.
●
Bridge protocol data unit (BPDU) guard shuts down Spanning Tree Port Fast-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 also
limits the number of concurrent multicast streams available per port.
Management and Control Features
The Cisco Catalyst 2350 Series Switches come with a set of management and control features.
These features include the following:
●
Cisco IOS
®
Software CLI support provides common user interface and command set with
all Cisco routers and Cisco Catalyst desktop switches.
●
Generic On-Line Diagnostics (GOLD) checks the health of hardware components and
verifies proper operation of the system data and control plane at run time and boot time.
●
VLAN1 minimization allows VLAN1 to be disabled on any individual VLAN trunk.
●
Internet Group Management Protocol (IGMP) Snooping for IPv4 and IPv6 MLD v1 and v2
Snooping provide fast client joins and leaves of multicast streams and limit bandwidth-
intensive video traffic to only the requestors.
●
Cisco VLAN Trunking Protocol (VTP) supports dynamic trunk configuration across all
switches.
●
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 four 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.
●
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 time stamp to all
intranet switches.
●
A comprehensive and convenient visual management system is provided by 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 and
bandwidth utilization.
●
Jumbo frames (9216 bytes) are available for advanced data and video applications
requiring very large frames.
