Re: Starting TCP

[DrFranken <midrange@xxxxxxxxxxxx>]

IP does NOT need to be running for the LAN console to function. It uses 
a short IP stack that is part of the LIC. This is why you can use the 
console while in dedicated system mode! Additional this interface is 
what's used for network based virtual optical drives so they too are 
available when in dedicated system.
