SD-WAN 2013.5 release notes

October 29, 2013

SD-WAN 2013.5 adds aggregation server failover. If an aggregator fails, it allows bonds to automatically move to a different aggregator within two minutes. SD-WAN has always been about reliability, and now you can eliminate the risk of an aggregator failure leading to an extended outage for your customers.

Bonding node

Additions

  • Nodes respond to heartbeat checks from the management server.
  • Routing of routed blocks on aggregators can be disabled using the “aggregator routing” option.
  • Routed blocks can be part of a private WAN routing container.

Changes

  • Routed blocks for private subnets are no longer routed by default on aggregators.

Patches

2013.5-0: Limited-release beta 2013.5-1: Initial public release Bonding admin Additions

  • Bonds can be configured with a secondary aggregator. If the primary aggregator fails, the bond is moved to the secondary aggregator within two minutes. Aggregator failover is coordinated by the management server.
  • Management server settings are shown on the System Info page.
  • The aggregator API has bonds_current and bonds_secondary fields, listing bonds which are currently assigned to the aggregator and which have the aggregator as their secondary, respectively.

Changes

  • The default balancing algorithm for new bonds has been changed to Flowlet.
  • The sort order of the aggregator list table can changed by clicking the header of the column to sort by.

Removals

  • Users can no longer change their username from the account edit form.
