NOTE: We recommend that you use the
save any configuration changes that you make to a multimember Virtual
Chassis configuration.
To maintain the master and backup roles of the existing members and ensure that the
new member switch functions in a linecard role, copy the following commands and paste
them into the terminal window:
[edit]
user@SWA-0# set virtual-chassis member 0 mastership-priority 255
user@SWA-1# set virtual-chassis member 1 mastership-priority 255
To ensure that the existing member switches retain their current roles and to add another
member switch in a linecard role:
Configure the mastership priority of SWA-0 (member 0) to be the highest possible
1.
value, thereby ensuring that it functions as the master of the expanded Virtual
Chassis configuration.
[edit virtual-chassis]
user@SWA-0# set member 0 mastership-priority 255
Configure the mastership priority of SWA-1 (member 1) to be the highest possible
2.
value. This setting is recommended for high availability and smooth transition of
mastership in case the original master becomes unavailable.
[edit virtual-chassis]
user@SWA-1# set member 1 mastership-priority 255
Interconnect the unpowered SWA-2 with SWA-0 and SWA-1 using the dedicated
3.
VCPs on the rear panel. See Virtual Chassis Cabling Configuration Examples for
EX4200 Switches for additional information.
Power on SWA-2.
4.
You do not need to configure or run EZ Setup on SWA-2. The identification
parameters that were set up for the master apply implicitly to all members of the
Virtual Chassis configuration. SWA-2 functions in a linecard role, since SWA-0 and
SWA-1 have been configured to the highest mastership priority values.
To verify that the new switch has been added as a linecard and that its VCPs are
operational, perform these tasks:
Verifying That the New Switch Has Been Added as a Linecard on page 955
Verifying That the VCPs Are Operational on page 956
Verifying That the New Switch Has Been Added as a Linecard
Verify that SWA-2 has been added in a linecard role to the Virtual Chassis configuration.
