Hello,

what is the question?

Internet connection is slow today. I'm not sure why it didn't post the questino the first time. Here goes.

I have a 7206 router connected to a 4506 switch. There is a 198.185.188.253/24 interface that is built on the gig0/1 interface. I am trying to move this network over to the 4506 and make it vlan188. I can do a no ip address and shutdown on gig0/1 on the 7206, and build vlan188 on the 4506. The vlan188 interface shows up and up on the 4506. I'm trying to trunk vlan188 out to some 2950 via the gbics. The configs look like this.

7206

switchport access vlan 188

If I do a sho vlan on the 2950 I get this output.

1003 token-ring-default act/unsup

1004 fddinet-default act/unsup

1005 trnet-default act/unsup

If I plug a network device into fa0/1 vlan188, and do a sho vlan again port fa0/1 doesn't show up under ports for vlan188. For example,

VLAN Name Status Ports

188 VLAN0188 active Fa0/2, Fa0/3, Fa0/4

I can't get any devices on the network using vlan188 because of this. All the other vlans work. Do I need to reboot the 7206 after I delete the 198.185.188.0 network? Any ideas as to what I'm missing? Sorry for the long post.

Thanks in advance

Can you post the 2950 config ? Also did you create the "layer 2" vlan on the 4506 ? Not the layer 3 SVI that appears to be there , if you do a show vlan on the 4506 does vlan 188 show up and active ???

I'm creating the layer 2 vlan then giving the interface an ip address. When I create vlan188 on the 4506 I am entering this.

vlan 188

name DNS-WINS

int vlan 188

ip address 198.185.188.253 255.255.255.0

no shut

router ospf 1

network 198.185.188.0 0.0.0.255 area 0

Vlan188 shows up and active on the 4506. I can also ping 198.185.188.253 address from other routers on the network. All the other vlans work too. They were also moved over from the 7206.

HI

As per u r trunking configuration i dnot see any vtp information configured on u r switches.i mean which is ur switch is functioning as a server or which one is as a client or u r using transparent mode.and i would like to see the trunk ports weather they r configured for the same encapsulation etc.

thanks

hope this helps
