Hi,

I have Cisco WS-C4510R+E with sup WS-X45-SUP7-E. IOS version on this switch is cat4500e-universal.SPA.03.04.05.SG.151-2.SG5.bin . Enterprises license is permanently installed on switch. I have configured VSS on this but i am not able to configure dual-active fast-hello on L2 link. only dual-active detection using PagP is supported. since we don't have neighboring devices support PagP. I want to use dual-active fast-hello using L2 links between two VSS switches.

I believe dual-active fast-hello on L2 link is supported on Release 3.6.1E. Please confirm whether i will have to change current IOS release from 3.4.5SG to Release 3.6.1E to support dual-active fast-hello link.

I also want to know what will be major features change if I upgrade current IOS release from 3.4.5SG to Release 3.6.1E    

Regards

Hi,

dual-active fast-hello is supported from release 3.5.0  

(reference link: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/release/note/OL_29985-01.html )

so is also supported in release 3.6.1 . 

You can see all feature changes in release notes for version 3.6.X

Best Regards,

Alessandro
