Introduction

Test Details: Goals of this test

Data Center Multi-Layer VPC design aggregation layer failure scenarios are depicted in this document. The tests involve a multiple VPC domain design with VPC extended from Core to Aggregation as well as Aggregation to Access. The Failure scenarios covered in this test document are the following:

  • Failure of the Peer Keepalive link - simulated by the shutdown of Ethernet1/1 on AGG1 router
  • Failure of a single link in the Peer-link bundle - simulated by shutting down either Ethernet2/1 on the AGG1 router
  • Failure of the peer-link port-channel - simulated by shutting down the Port-channel 3000 interface between AGG1 and AGG2 routers
  • SFM module failure on Aggregation router
  • Supervisor failure/switchover on an aggregation router
  • Linecard failure on the AGG1 router
  • Failure of an aggregation node

Data to Record

Verification of operation of VPC and its configuration using the following commands:

  • show vpc brief
  • show port-channel summary
  • show port-channel traffic
  • show run int port-channel xxxx
  • show run vpc

Estimated Time: 120 minutes

Topology

Procedures

1. This document highlights the failure scenarios with the above mentioned topology in the Aggregation layer.

2. The following failures were conducted on the Aggregation layer to verify the operation and resiliency of VPC in a multi-domain VPC environment with the entire Data Center running on VPC.

  • Failure of the Peer Keepalive link - simulated by the shutdown of Ethernet1/1 on AGG1 router
  • Failure of a single link in the Peer-link bundle- Simulated by shutting down either Ethernet2/1 on the AGG1 router
  • Failure of the peer-link port-channel- Simulated by shutting down the Port-channel 3000 interface between AGG1 and AGG2 routers
  • SFM module failure on Aggregation router
  • Supervisor Failure/switchover on an aggregation router
  • Linecard failure on the AGG1 router
  • Failure of an aggregation node
