You've just found out the maximum number of VLANs supported by your switch
;-) Officially the base model 2950 supports 64 VLANs (default VLAN plus
64). The 2950C/2950T/2950Gs support up to 250 VLANs.
You can verify what your switch supports by issuing the "show vtp status |
include Maximum VLANs" command.
