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
