Runs all VC management daemons andcontrol protocols
Communicates with all VC member switchesfor interface OIR, forwarding hardwareprogramming, xmit/rcv updates
Line Card switches (LC) All other non-Master or Backup VC memberswitches
Runs JUNOS in a Line Card role
Responsible for programming local hardware
In the event of a Master or Backup failure, oneof the Line Card switches will be made the
new backup switch
Backup switch (RE1) One switch is elected Backup Backup RE runs JUNOS in a backup role

Virtual Chassis Management
Single management interface
Individual Ethernet management ports (me0) on Member switches aretied to a special management VLAN associated with a single L3 virtualmanagement interface (vme) by default
vme interface always follows the Master RE
best practice: Always configure the vme interface rather than the me0
interfaces
Single management IP address The virtual chassis is managed as a single network element; therefore it
will have only one management IP address that should be configured onvme interface
Single virtual console Connection to a console on any Member switch in a virtual chassis will
be redirected to the VC Master by virtual console software running on allMember switches
