Cisco 9407 Stackwise Virtual - Fast Hello on Copper interface?

[shamg1974]

I'm attempting to configure fast hello on two copper interfaces on my 9407 chassis' running SVL. It won't give me the option to do so under config mode:

Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#int g1/1/0/48
Switch(config-if)#stack
Switch(config-if)#stackw
Switch(config-if)#stack?
% Unrecognized command
Switch(config-if)#stackw?
% Unrecognized command

Is it possible to do this over 1Gb copper? If so, why am I not getting the option. I'm running IOS-XE 16.9.3.

Thanks,

Shameer

Hi

supervisor module only

Fast Hello dual-active detection is supported only on supervisor module ports. Enhanced PAgP dual-active detection is supported on supervisor module ports and line cards.
