I beg to differ:
interface Vlan6
ip address 133.5.8.8 255.255.255.0
!
interface Vlan20
ip address 10.115.12.1 255.255.255.0 secondary
ip address 10.115.6.1 255.255.255.128
no ip redirects
standby 1 ip 10.115.6.2
standby 1 timers 3 5
standby 1 priority 100
standby 1 preempt
standby 2 ip 10.115.12.2
standby 2 timers 3 5
standby 2 priority 100
standby 2 preempt
!
interface Vlan21
ip address 10.115.6.129 255.255.255.128
!
interface Vlan22
ip address 10.115.7.1 255.255.255.248
Since I disabled trunking and have no devices connected to the above VLANS.,
they change to down.
I have devices connected to VLANS 1, 2, and 6.
VDL-CAT#sho ip int brie
Interface IP-Address OK? Method Status

Vlan1 unassigned YES NVRAM up

Vlan2 unassigned YES NVRAM up

Vlan6 128.125.10.1 YES NVRAM up

Vlan20 10.115.6.1 YES NVRAM up
down
Vlan21 10.115.6.129 YES NVRAM up
down
Vlan22 10.115.7.1 YES NVRAM up
down
Now I will re-enable trunking.
Enter configuration commands, one per line. End with CNTL/Z.

VDL-CAT(config-if)#

changed state to down
2w4d: %EC-5-CANNOT_BUNDLE2: Fa0/1 is not compatible with Fa0/2 and will be
suspended (dtp mode of Fa0/1 is on, Fa0/2 is off)
VDL-CAT(config-if)#int fa0/2

VDL-CAT(config-if)#
2w4d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2,

After you create an SVI and assign an ip address you must enter "no
shutdown" on the SVI to make it active. This has nothing to do with what
is connected to the switch.
