FA 0/1 on SW_1 needs to be assigned to VLAN 20.
FA 0/1 on SW_2 needs to be assigned to VLAN 20.
VTP is not working properly between SW_1 and SW_2.
Interfaces FA0/1 on SW_1 and SW_2 need to be configured as trunk ports.
Interfaces FA0/3 on both switches need to be configured as access ports.
The management VLAN is VLAN 99.
The only VLAN that can be applied to switch ports is VLAN 99.
The only VLANs that can be applied to switch ports are VLANs 1 and 99.
The switch will only be able to forward frames for hosts on the 10.99.0.0 network.
The Spanning Tree Protocol has been disabled on one switch.
The Spanning Tree Protocol has been disabled on both switches.
The IEEE 802.1Q trunking port has a speed mismatch on one of the switches.
The SwA port is configured as a trunk port and the SwB port is configured as an access port.
The SwA port has IEEE 802.1Q trunking enabled and the SwB port has ISL trunking enabled.
Because there is a cabling problem on VLAN 99
Because VLAN 99 is not a valid management VLAN
Because VLAN 1 is up and there can only be one management VLAN on the switch
Because VLAN 99 needs to be entered as a VLAN under an interface before it can become an active interface
Because the VLAN 99 has not been manually entered into the VLAN database with the vlan 99 command

Ports are manually configured to be in the forwarding state.
Ports listen and learn before going into the forwarding state.
Ports must be blocked before they can be placed in the disabled state.
It takes 15 seconds for a port to go from blocking to forwarding.
