Please confirm
Switchport trunk allowed more to do with prunning rather than permitting, I
though one has to use
switchport multi vlan 1,xx,yy
switchport mode multi

I don't think you need to make 40 the managment vlan. Just trunk the port
allowing all vlans that need to be transported. I would also use dot1.q, I
always have better experiance with it. You may want to double check to see
if you created the vlan 30. I did the same thing you did and notice that
vlan 30 does not exist in the show vlan. Rich
s1(config)#int fas 0/21
s1(config-if)#switchport trunk allowed vlan 40,30
s1(config-if)#^Z

have been asked to set a management interface on the switch on vlan 40, and
I am trying to bridge via IRB on the router between the switch and the
ethenet, vlan 30. I have no connectivity between the switch and the router.
Here are some configs:
switch:
hostname 3550
!
interface FastEthernet0/12
switchport trunk encapsulation isl
switchport trunk native vlan 40
switchport trunk allowed vlan 10,20,30,40,1002-1005
switchport mode trunk
no ip address

interface Vlan40
ip address 145.1.36.100 255.255.255.0
!
ip default-gateway 145.1.36.6
ip classless
ip http server
!
end
router:
hostname R6
!
bridge irb
!
interface FastEthernet3/0.30
encapsulation isl 30
no ip redirects
bridge-group 1
!
interface FastEthernet3/0.40
encapsulation isl 40

ip address 145.1.36.6 255.255.255.0
