That shouldn't happen! Take a look at "show vlan brief" to make sure no access ports are assigned to VLAN 10. Also take a look at "show interface trunk" to make sure you don't have any other trunk ports you forgot about! Once you remove all ports though, your SVI should go down fairly quickly. At least it always has for me! HTH,

But say I have vlan 10 in vlan database and int vlan 10 .. no acess port for vlan 10 , i have a trunk carrying vlan 10 .. as expected my interface vlan 10 was UP and UP. Now if i remove vlan 10 from trunk ( switchport trunk allowed vlan except 10 ) ; i still have my SVI in UP state. any light on this .. what i have deduced is that presence of vlan in vlan database is only point to be kept in mind. Gaurav Madan. 2008/2/20 Brian K Valentine <[EMAIL PROTECTED]>: Hi, I'm new to the study list, but I believe I can contribute to this issue. My understanding is this. In order for the SVI for that VLAN to come "up and up", you need to have an interface on that local switch assigned to that VLAN. In other words, at least one of the ports must have that VLAN assigned to it as an access VLAN or at least one of the ports must be trunking that VLAN. This also implies that the VLAN exists in the local VLAN database.

Under what circumstances do we have int vlan <> in down state ? I know that if we create " int vlan x " and vlan x do not exist in vlan database then there will be no spanning tree instance for this vlan and the int vlan x will be down .. Is there some other case also ; where int vlan x is down .. I note that only vlan presence is the criterai .. Even if i disable STP for this vlan .. i see interface in UP state . Thnx Gaurav Madan.
