show system switchover command missing in 11.1R1

I'm setting up a pair of new EX4500es in a VC. Attempted to configure GRES, but the status command that used to work in earlier versions, and that is clearly documented in the Junos OS 11.1 High Availability Configuration Guide, does not work:

 

 

{master:0}
root@cs1-osl2> show configuration chassis redundancy 
graceful-switchover;

{master:0}
root@cs1-osl2> show system switchover
                           ^
syntax error, expecting <command>.

 

 

Any idea how to check if GRES is working properly or not?

Re: show system switchover command missing in 11.1R1

I don't have 4500, only 4200 but this worked on later releases. Currently have only 10.0 to test and "check" command isn't showing notice or timer that graceful switchover could be done.

 

request chassis routing-engine master switch check

and

request chassis routing-engine master switch

Humm..

 

 

root@cs1-osl2> request chassis routing-engine master switch check 

{master:0}
root@cs1-osl2> 

 

The switch command works but I don't know if GRES does what it supposed to do or not.

Hi,

 

http://www.juniper.net/techpubs/en_US/junos9.5/topics/task/verification/virtual-chassis-gres-verifyi...

you should connect to backup switch (your master is now 0, so request session member 1 <= backup). And then issue command show system switchover. I was not able to issue that command on master. Same as you.

 

 

{master:0}
user@switch> request session member 1

Thank you! I did the command on the switch holding the RE role. Looks good from the backup's point of view:

 

 

{backup:0}
root@cs1-osl2> show system switchover 
Graceful switchover: On
Configuration database: Ready
Kernel database: Ready
Peer state: Steady State

Re: show system switchover command missing in 11.1R1

To verify graceful Routing Engine switchover is configured, on the backup Routing Engine (re1) issue the show system switchover command. The output should be similar to the following example. The Graceful switchover field state must be On.
{backup}

user@host> show system switchover

Graceful switchover: On
Configuration database: Ready
Kernel database: Ready
Peer state: Steady State
