So further to this issue I've now discovered this particular switch won't even work the same as my other switch that is not using dot1x supplicant controlled transient
So to make that clear: I have two NEAT switches, identically configured except for different usernames and management IP's (same VLAN). They both authenticate to ISE fine but the second one refuses to communicate on the management or any other VLAN.
On the authenticator switch I see:
MSBBSWAS01#show cisp interface G6/0/30
CISP Status for interface Gi6/0/30 ---------------------------------- Version: (not negotiated) Mode: Authenticator Peer Mode: Auth State: Idle
