VSS Dual Active Detection configuration question

[rshum]

In IOS verson 12.X there was a Bidirectional Forwarding Detection configuration however in IOS 15.0 this isn't available at least not with the same syntax. Is this feature not available in 15.0?

In 12.X this was the syntax of the command:

switch virtual domain <number>

dual-active pair interface GigabitEthernet1/X/X interface GigabitEthernet2/X/X bfd

BFD for VSS dual active detection is deprecated in newer versions of IOS.  The only 2 options are: Fast hello and ePAGP.
