Hi, the command is assert-leader.
The config-sync commands are documented here .
And legacy SEMP is documented here .
It is definitely not trivial to find the correct xml body.
I used the xsd spec semp-rpc-soltr.xsd, which can be downloaded from the Solace product download page, where you can also download the enterprise software broker.
The command can be executed on system level or on vpn level. The SEMP bodies are:
default
Instead of the name default you can also use wildcard * for multiple VPNs.
The trick here is that the message-vpn is called vpn-name in SEMP.
