John,
I appreciate the damage control, however, most of us in the operational
community that have hundreds or even thousands of VIPs deployed have come to
greatly rely on VIP consoles for troubleshooting. I can think of a great
deal of important information that can be found only at a VIP console. For
example, there is no way to get HSSI clock information from a PA-(2)H unless
you are at the console. 'show vip accumulator' can report buffer or rx-ring
issues on cards. A dead IPC Seat process can be cured by issuing a reload
form the VIP console. The list goes on and on...
Perhaps some of the commands that are useful to a non-TAC engineer should be
made available thru the RSP, this way, some of the issues that you mention
are not likely to happen.
I will stress, in concert with John, that caution must be observed when in
the VIP console, but I don't think any moreso than if one is in enable mode
and doesn't know the outcome of a 'no router bgp xxx' at an exchange point.
One final thing to note: Most of the usual suspects on this list have been
mucking thru the VIP console for over two years. The secret has been out
for a long time. Must be all thos ISP Expert Support guys... ;)
regards,
chris
