Hi! Silly question: is it possible to perform "incremental upgrade" on ex-series virtual-chassis ? I.e., upgrade some switches (using 'request system software add member NN'), switchover master to 'upgraded' part, then upgrade remaining switches ?
Juniper documentation is not so clear on this topic - on one hand we have command that allows upgrade of selected chassis member and KB10840 suggests that "Virtual Chassis software can be upgraded for the entire VC or you can upgrade one individual member of the VC", on other - KB16756 suggests that "for a standalone EX4200 switch to join an existing Virtual Chassis configuration, it had to be running the same version of software that was running on the Virtual Chassis master" and that since 10.0 master switch has ability to "ability to automatically update the software on a new member switch so that it can join the Virtual Chassis configuration" (i.e., in this application fresh upgraded switch will be automatically downgraded back to the version master running). Or am I missing something ? -- In theory, there is no difference between theory and practice. But, in practice, there is. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
