QuickSpecs
Technical Specifications
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.
Embedded Event Manager (EEM) allows customers to set up trigger points
based on certain events to automatically take actions, thus automating
network management
VPN routing/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 Virtual Blade Switch technology, allows the Cisco
Catalyst Blade Switch 3120 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.
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
