WAAS Express

Is anyone running WAAS Express on their G2 routers?  What are you experiences with it?

Re: WAAS Express

Disclaimer: This is purely my personal observation rather than any factual data from the field.

This is a new feature and one that requires a lot of new processing.

Rule of thumb says 3-4 software revisions since feature release is when I would consider running it ;-)

That being said there have not been to many pure WAAS express cases in TAC (ones that root caused would be a fault in WAAS express code and not external - letancy, packet drop etc etc), development has done a good job getting read of a lot of potential issues before the release.

However as this feature will get more and more exposure we might see more issues popping up.

Read carefully restrictions and contact your account team prior to implementing!

Hope this helps.

We just ordered five 2911s with the WAAS express bundle. They are scheduled to be delivered before the end of the month. Did you deploy or just asking for information?

Yes. WAAS express is supported on G2 routers. Further documentation can be found here:

http://www.cisco.com/en/US/partner/prod/collateral/modules/ps2797/ps9750/data_sheet_c78-605215.html

Virtual blades are supported on all WAVE devices and on certain models   of WAE devices. On unsupported WAE devices, the virtual blade   configuration screens are nonfunctional.

In addition to that, yes, we have customers running WAAS express on G2 routers. All the existing / resovled issues are mentioned in the release notes:

Hope this helps.

WAAS Express

Does WAAS Express require a WAAS Infrastructure or can WAAS Express enabled routers optimize amongst themselves?

WAAS Express

Bill,

It will techincally work, but is not a recommended deployment model.

You lose DRE when peering two WAAS Express devices.  Since WAAS Express only does DRE decode, having WAAS Express devices on both ends of the connection means you effectively limit yourself to only TFO + LZ even if the policy is set for TFO DRE LZ (e.g. Full optimization).  This is why WAAS Express is recommended to peer with a WAAS appliance at the head end.
