Troubleshooting VSS Failure

Posted by: admin  :  Category: CCIE, CCNP, Switching, Troubleshooting




In this article we are going to discuss how a VSS pair reacts during a failure. There are three possible failure scenarios that may occur.

  1. Link failure in the multi-chassis port channel link.
  2. Active supervisor engine failure.
  3. VSL failure.

Basic VSS Pair Configuration

Posted by: admin  :  Category: CCIE, CCNP, Switching


Virtual Switching System (VSS) allows two Cisco Catalyst 6500 or 4500 switches to be connected together so that they appear to the network as a single switch. Other devices in the network will see the VSS configured switches as a single switch, which allows the engineer the ability to create multi chassis Ether-Channels between the VSS pair and other devices while appearing to other protocols like spanning-tree as a single switch.

Switch Stack

Cisco switch stacks are an affordable alternative to the more expensive Cisco Catalyst 4500 and 6500 modular switching chassis. The cisco switch stack provides single point of management, redundancy and is easily expanded to provide to additional port density. What is a switch stack?
