[f-nsp] ISSU and hitless upgrade on NetIron (Was Re: Experience with 5.4.00c on XMR?)

[Youssef Bengelloun-Zahr]

Hello Greg,

Yes, I'm already aware of that.

We were told ISSU was 'disabled' as a precaution because of the introduction of Openflow support in 540a I believe.

It should come back soon, I'm reading the upgrade notes at each release very religiously.

Also, regarding hitless upgrade, we are pushing very hard a customer to have MPLS support (and it's applications).

We had a call with Jason Kleeh in April about this. We feel some critical features like theese are missing and have submitted several RFEs with our se.

Also discussed this with Pete Moyer at last EBC in february.

Thanks.

We're planning software updates for the summer and that looks like a reasonably deep release but it's only been on the street for about 6 weeks. Just wondering if anyone has experiences either way regarding this software release. Thanks in advance!
