Justed upgraded to CNA 5.8(6), when I try to configure any port's VLAN of one of our old switches (Catalyst 3548-XL IOS 12.0(5)WC17)
I am not able to do it anymore. It just shows the error this message :
Error: Modify Port Mode com.cisco.cpnm.features.dsbu.c3500.vlan.C3500Vlan cannot be cast to com.cisco.features.dsbu.defn.vlan.CommonVlan
Is there any workaround ?
