## Virtual Chassis
|
|
|
|
|
|
-Virtual Chassis (VC) is a simple way of connecting multiple close or distant switches into a ring topology and managing them as a single logical device. All devices share a common management IP address. It simplifies loop prevention (otherwise using STP) and improves fault tolerance. A VC has one switch as master routing engine, one switch as backup routing engine and the remaining switches as linecards. The master is elected based on (in order) highest mastership priority, which member was master last time, which switch has been a member the longest, and which member has the lowest MAC address. You typically want to set the mastership priority to 255 for the two switches you want as master and backup routing engines.

+- Virtual Chassis (VC) is a simple way of connecting multiple close or distant switches into a ring topology and managing them as a single logical device. It simplifies loop prevention (otherwise using STP) and improves fault tolerance.
|

|
+- Roles: A VC has one switch as master routing engine, one switch as backup routing engine and the remaining switches as linecards.
|
|
|
+- Mastership election: The master is elected based on (in order) highest mastership priority, which member was master last time, which switch has been a member the longest, and which member has the lowest MAC address.
|
|
|
+- LEDs: The "MST" LED will be solid green on the master, blinking green on the backup and off on the linecards.
|
|
|
+- Alarms: Alarms for a specific device will only show on the master and the actual device.
|
|
|
+- FPCs: Each switch will show as separate FPCs (Flexible PIC (Physical Interface Cards) Concentrators).
