Solved: Sup2T is not booting after deleting vlan.dat file

Rasika Nayanajith · ‎09-19-2012

Hi Guys,

We have recently purchased new Sup2T to replace the Sup720. When we tried to copy the vlan.dat file across we are facing this issue. Sup2T is not booting up once delete the original vlan.dat file of the Sup2T & reload. Here is the console output during the process. Can anyone help what to do to get this Sup2T working.

Router#delete const_nvram:vlan.dat

Delete filename [vlan.dat]?

Delete const_nvram:vlan.dat? [confirm]

Router#

!

Router#reload

System configuration has been modified. Save? [yes/no]: n

Proceed with reload? [confirm]y

Hello,

It seems that the console becomes stuck after the Sup starts to load the configuration file (assuming from the fact that the switch complains about the lack of "ip multicast-routing" command which confirms that the startup-config is being processed). Can you set your configuration register to 0x2142 in the ROMMON and try booting this way? This should prevent the switch from loading the configuration file that perhaps has some troubles starting.

Best regards,

Peter

Hi Peter,

Thanks for the suggestion, yes it worked indeed.

Once bypass the NVRAM, we have deleted the corrupted startup config & apply config from fresh.
