How to clear configuration of MA5200 serials and recover wrongly-deleted document?
For MA2.10-71xx or VRP3.30-2xxx Version
Clear with delete and not reset recycling bin, and use undelete commands and recover deleted document and restart it.
First use delete/u and then reset recycle bin or delete with resetsaved-configuration, and have no way to do it. If there is backup at other machine, use Zip and compress as vrpcfg.zip document and load it to the system. For MA2.10-71xx, load it to rout file of flash. For VRP3.30-2xxx, load it to any file and recover data from relevant document with startup command, then restart the system.
