Managing A Virtual Chassis
Configuring Virtual Chassis
For more information on using the lowest MAC address to determine the Master switch in a VC, refer to
the diagram below:
1
A group of four switches are connected using the dedicated
VFL ports. All switches are powered on within approximately
2 minutes of each other. In addition, there is no
vcsetup.cfg file on any of the switches.
00:d0:95:b2:3c:8e
00:d0:95:b2:2a:ab
00:d0:95:b2:1c:ff
00:d0:95:b2:5b:8d
2
When the chassis are booted, system software detects the
lowest MAC address. In this example configuration, the
lowest MAC address is 00:d0:95:b2:1c:ff. It is assigned
chassid-id 1 and becomes the Master.
Chassis-id 4 - Slave
Chassis-id 3 - Slave
Chassis-id 1 - Master
Chassis-id 2 - Slave
3
The system software configures the remaining chassis as
Slaves and assigns the next numerical chassis-id based on
its VFL connection to the Master. This chassis-id information
is saved to the vcsetup.cfg file, located in the
switch’s /flash file directory.
Automatic Master/Slave and Chassis-id Assignment
:
Chassis-id 1- Master
Chassis-id 2- Slave
1
A virtual chassis of three switches is already up and running.
A new switch is added to the VFL connections and powered
on.
Chassis-id 3- Slave
Chassis-id 1- Master
Chassis-id 2- Slave
The new switch gets assigned the next available chassis-id
and joins the virtual chassis.
Chassis-id 3- Slave
Chassis-id 4 - Slave
