Hi We have several 450a switches in one of our solutions and have had a few failures recently, is it possible to recover a configuration file from a failed switch if it only bootd to the BootRom prompt ?

Hello rod.barton,

 

try the following from BootRom→ 

boot 3 

linux

cd /config

cat <config’s name> ### copy xml to a text file and save as <name.cfg>

After all just do power reboot

Example:

BootRom > boot 3

Loading EXOS Diagnostics ... 

Running Image ...

SummitX Diagnostics Mode Enabled, Starting Diagnostics....

slot1>linux
cd /config
ls 
primary.cfg
vmt
cat primary.cfg
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="exos_config_display.xsl"?>
<xos-configuration version="15.3.5.2" date="Tue Dec 17 06:12:51 2019" creator="admin" checksum="0" platform="X450a-24t">
<xos-module-aaa version="3.0.0.3">

<radius_service><server_set>1</server_set><type>1</type><timeOut>3</timeOut><enable>0</enable></radius_service>
<radius_service><server_set>2</server_set><type>0</type><timeOut>3</timeOut><enable>0</enable></radius_service>

 

Also as all X450a are not under warranty now you may try to remove CompactFlash card from affected switches and copy config via CF card reader.

 

Best Regards,

Nikolay

The config file may not be recovered directly from the BootROM, however to restore the switch in a boot loop, you could attempt a BootROM recovery, which is documented in the following article. This will wipe all config from the switch and you will need to obtain an EXOS image for the X450a:

Please also note that the X450a is no longer supported and will support EXOS up to v15.3.5.2-patch1-19
