A moje mala pomucka pro 3548, ktera neumi //range//.
<code>
for i in `seq 43 48`; do
   echo interface FastEthernet0/$i
   echo switchport access vlan 100
   echo switchport trunk allowed vlan 4,10,98,100
   echo switchport mode trunk
   echo switchport trunk encapsulation dot1q
   echo spanning-tree portfast
   echo exit
done
</code>


Also note that a 3548XL is a Layer 2 switch. This means that the only thing it needs an
IP address for is for management. Notice that even though you have (and have been
allowed to) configured IP addresses on interface VLAN 100/200, both those interfaces are in shutdown. Only one VLAN interface with an IP address can be active at any given time, and by default it is VLAN 1 on a Cat3548XL.
