Supervisor Engine (Cisco)

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The Cisco Supervisor Engine is the heart of many of Cisco's switches. The Supervisor Engine has evolved several times. While it is the management segment of many routers, the power of the switch is often much greater than that of the Supervisor Engine because one of the features of many switches is that dozens of the functions are accelerated by ASIC chips.

Abridged list of features:

  • 802.1q VLAN
  • Spanning Tree Protocol
  • Ether Channel
  • Jumbo Frames
  • (E)IGRP, OSPF, RIP (2), Static Routing
  • BGP, IS-IS
  • QOS
  • Some have Layer 3 & 4 Switching
