user@device> request virtual-chassis mode mixed reboot
9. On each individual member switch, configure the ports that will be used to interconnect
the member switches into VCPs using the following command:
user@switch> request virtual-chassis vc-port set pic-slot pic-slot-number port port-number
where pic-slot-number is the PIC slot number.
For instance, if you wanted to set port 0 on the QSFP+ interface on PIC slot 2 as a
VCP:
user@switch> request virtual-chassis vc-port set pic-slot 2 port 0
The VCPs automatically bundle into a Link Aggregation Group when two or more
interfaces of the same speed are configured into VCPs between the same two member
switches. See Understanding Virtual Chassis Port Link Aggregation.
NOTE: If you do not edit the Virtual Chassis configuration file, a
nonprovisioned configuration is generatedbydefault. The mastership priority
value for each member switch is 128. The master Routing Engine role is
selected by default. You can change the role that is performed by the
members by modifying the mastership priority. See Configuring Mastership
of a Virtual Chassis (CLI Procedure). We recommend that you specify the
same mastership priority value for the desired master and backup members.
In this example, the highest possible mastership priority has been assigned
to two members. However, the member that was powered on first has higher
prioritization according to the master election algorithm. See Understanding
How the Master in a Virtual Chassis Is Elected. The other members use the
default mastership priorityin this example, which configures them to function
in the role of linecard.
NOTE: If you want to change the member ID that the master has assigned
to a member switch, use the request virtual-chassis renumber command.
