a few days ago i try to change a switch 3400 for a new 3400 enhanced and when a conect a trunk cable on this swith on a one port this port doesn´t going up. this port are configured with a trunk configuration whit all vlans what the old 3400 have.
when we make a trhoubleshoting after the first aptemp we see this strange log.
Mar 28 06:03:22: %SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk FastEthernet0/24 VLAN1.
Mar 28 06:03:22: %SPANTREE-7-BLOCK_PORT_TYPE: Blocking FastEthernet0/24 on VLAN0001. Inconsistent port type.
