Management and Control Features
Each Cisco Catalyst 3750-E Series stack is managed as a single object and has a single
IP address. The primary management and control features in the Cisco Catalyst 3750-E
Switches include:
●
Cisco IOS Software CLI support provides common user interface and command set with all
Cisco routers and Cisco Catalyst desktop switches.
●
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.
●
Generic On-Line Diagnostic (GOLD) checks the health of hardware components and
verifies proper operation of the system data and control plane at run time and boot time.
●
Virtual routing and forwarding (VRF)-Lite enables a service provider to support two or more
VPNs, with overlapping IP addresses.
●
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.
●
Smart Multicast, with Cisco StackWise Plus technology, allows the Cisco Catalyst 3750-E
Series to offer greater efficiency and support for more multicast data streams such as video
by putting each data packet onto the backplane only once.
●
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.
●
Multicast VLAN Registration (MVR) continuously sends multicast streams in a multicast
VLAN while isolating the streams from subscriber VLANs for bandwidth and security
reasons.
●
Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from
degrading overall systems performance.
●
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.
●
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 timestamp to all
intranet switches.
