Configuration, Operation, and Maintenance
You configure and manage almost all aspects of a VC via the VC’s master RE. However, you can also configure VC parameters when an EX4200 is a standalone switch and not actually attached to other switches. This is because each EX4200 switch has some innate characteristics of a VC by default. A standalone EX4200 switch is assigned member ID 0 and is the master of its own (and therefore single-member) VC, which allows you to configure VC parameters on a standalone switch.
When the previously standalone switch is interconnected with an existing VC, the VC configuration statements and any VCE uplink settings that you previously specified on the standalone switch remain part of its configuration, where they can do such things as influence mastership reelections. Once a switch becomes part of a VC, the current VC master synchronizes its configuration copy to all member switches, overwriting any local changes that conflict with the current master’s settings.
As with configuration, VC operation and diagnostic troubleshooting is generally performed through the master switch. In a typical configuration, a single virtual IP address is shared among all VC switch members, and any incoming traffic received by a VC member for that shared address is automatically redirected to the current master RE. In a similar manner, a virtual console service redirects console input on any VC switch member to the master RE’s console using an internal communications path. ...
