Users are unable to manage SRX Series and J Series devices through J-Web. Error message says this is due to "the config is too large for J-Web to handle".
The only workaround is to use the CLI or NSM.
Trying to manage device via J-Web results in the following error message being generated:
'FATAL ERROR: The configuration on the router is ' . 'too large for JWeb to handle. Please use the CLI to ' . 'manipulate the configuration.';
There is a limitation to managing a device via J-Web based on the config size on some models of SRX. When the XML config size reaches or exceeds the maximum, the following error message appears:
The XML file size limits are as follows:
To determine the XML config size, go to the operational prompt, and output the config to xml file format, using the syntax:
show config | display xml | save config-xml
From the shell, see the config-xml in the directory listing, to determine the file size of the XML config.
config-xml
