Hi,
On all switchs access, the spanning-tree add strange value when I create new Vlans from Distrib Layer,
and no association is created with any interface with spanning-tree vlan 700, see below in this exemple,
until I reboot the switch.
somebody already saw this values ?

After installed the good IOS, all working perfectly.
