Private VLANs

Private VLANs provide port-based security and isolation between ports within the
assigned VLAN. Data traffic on downlink ports can only be forwarded to, and
from, uplink ports.
Protocol-Independent Multicasting (PIM)
This multicast routing protocol floods multicast traffic downstream, and calculates
the shortest-path back to the multicast source network via reverse path forwarding.
PIM uses the router's IP routing table rather than maintaining a separate multicast
routing table as with DVMRP. PIM - Sparse Mode is designed for networks where
the probability of a multicast client is low, such as on a Wide Area Network. PIM -
Dense Mode is designed for networks where the probability of a multicast client is
high and frequent flooding of multicast traffic can be justified.
Remote Authentication Dial-in User Service (RADIUS)
RADIUS is a logon authentication protocol that uses software running on a
central server to control access to RADIUS-compliant devices on the network.

Remote Monitoring (RMON)

RMON provides comprehensive network monitoring capabilities. It eliminates the
polling required in standard SNMP, and can set alarms on a variety of traffic
conditions, including specific error types.
Rapid Spanning Tree Protocol (RSTP)
RSTP reduces the convergence time for network topology changes to about 10%
of that required by the older IEEE 802.1D STP standard.
Routing Information Protocol (RIP)
The RIP protocol seeks to find the shortest route to another device by minimizing
the distance-vector, or hop count, which serves as a rough estimate of transmission
cost. RIP-2 is a compatible upgrade to RIP. It adds useful capabilities for subnet
routing, authentication, and multicast transmissions.
Simple Network Management Protocol (SNMP)
The application protocol in the Internet suite of protocols which offers network
management services.
