Hello,
during configuration of a cisco WS-C2350-48TD (PowerPC405) processor (revision A0) with 131072K bytes of memory switch
running flash:/c2350-lanlitek9-mz.122-52.SE/c2350-lanlitek9-mz.122-52.SE.bin
i found that after minimal config and then switching from vtp transparent to vtp version 3 the switch will crash and go into endless-boot and write flashh full of crashinfo files. Since serial break did not help, i had to go to the switch and use the button on the front to come into the bootman to be able to clear the config file and recover .
Here ist a short way to reproduce it (i tried an other 2350-48 for that):
conf t
user cisco privilege 15 password cisco
enable secret cisco
vtp mode transparent
exit
wr
conf t
!
vlan 2
name vvv-2
!
vlan 3
name vvv-3
!
vlan 4
name vvv-4
!
!... etc...
!
vlan 98
name vvv-98
!
vlan 99
name vvv-99
!
exit
exit
wr

Processor board ID FDO1330R083
Here the boot-loop-crash-write starts.
Any Ideas ?
I didn't find buginfos for this or newer IOS.
Will this happen also for the near relative 3560E ?
Thank you for any hint,
Jürgen.
