G8264 Command Reference for ENOS 8.4
To improve customer technical support, your customer support representative can
assign your switch an Entitlement Serial Number (ESN) at the time you request
support. The ESN can be conveniently stored on the switch using the following
command:
RS G8264(config)# boot esn <Entitlement Serial Number>
The ESN helps to locate your switch's identifying information when you call
technical support for help in future.
