The Question is:
Is there a way to see the OPCOM messages with out the OPER priv.
The Answer is :
Not without having been explicitly or implicitly granted the access
by a sufficiently privileged user, of course. Options for granting
the access can include a local and installed privileged image, by
explicitly enabling another terminal as an operator from a process
that is running with OPER privilege, or by non-default protections
on the operator log. There are certainly other approaches for
granting privileges or privileged access to non-privileged users,
and there are examples of various techniques available.
