try:
interface FastEthernet0/19
switchport trunk encapsulation dot1q
switchport mode trunk
using "switchport multi" just overlaps vlans - & hence broadcast domains -
on regular ethernet encapsulation - this is at best ugly
if you need to limit the vlans permitted on a trunk then try:
switch(config-if)#switchport trunk allowed vlan ?
WORD VLAN IDs of the allowed VLANs when this port is in trunking mode
add add VLANs to the current list
all all VLANs
except all VLANs except the following
remove remove VLANs from the current list
