NOTE: Router performance might change if the standby Routing Engine's
configuration differs from the former master's configuration. For the most
predictable performance, configure the two Routing Engines identically,
except for parameters unique to a Routing Engine, such as the hostname
defined at the [edit system] hierarchy level and the management interface
(fxp0 or equivalent) defined at the [edit interfaces] hierarchy level.
To configure Routing Engine-specific parameters and still use the same
configuration on both Routing Engines, include the appropriate configuration
statements under the re0 and re1 statements at the [edit groups] hierarchy
level and use the apply-groups statement. For instructions, see the Junos OS
System Basics Configuration Guide.
To switch HCM mastership to the backup HCM, use the following command:
user@host> request chassis routing-engine master switch
warning: Traffic will be interrupted while the PFE is re-initialized
Toggle mastership between routing engines ? [yes,no] yes
Resolving mastership...
Complete. The other routing engine becomes the master.
The HCM that was master is now the backup HCM.
To check HCM status and mastership after a switchover, use the following command:
user@host>show chassis environment hcm
HCM 0 status:
State
FPGA Revision
HCM 1 status:
State
FPGA Revision
To switch HCM mastership from the backup to the default master, use the following
command
user@host>request chassis routing-engine master switch
warning: Traffic will be interrupted while the PFE is re-initialized
Toggle mastership between routing engines ? [yes,no] (no) yes
