Some Data can not pass through VLAN

[arie.yanto]

Hi All,

I have a problem, here are the situation

- 1 Catalyst 3750

- 1 Catalyst 2960

- 4 Finger Print

- 1 HUB

Configuration

- Catalyst 3750

         Interface VLAN182

               IP Address 10.62.182.254 255.255.255.0

         Interface G0/2

               Description Finger Print Server

               Switchport mode access

               Switchport access vlan182

- Catalyst 2960

         Interface F0/1

               Description Finger Print 1

               switchport mode access

               switchport access vlan182

         Interface F0/2

               Description Finger Print 2

               switchport mode access

               switchport access vlan182

         Interface F0/3

               Description Finger Print 3

               switchport mode access

               switchport access vlan182

         Interface F0/4

               Description Finger Print 4

               switchport mode access

               switchport access vlan182

         Interface F0/5

               switchport mode access

               switchport access vlan182

         Interface VLAN182

               no ip address

         IP default-gateway 10.62.182.254

Trunking Port

- Catalyst 3750

       Interface G0/1

           Switchport mode Trunk

           Switchport trunk encap dot1q

- Catalyst 2960

      Interface F0/24

           Switchport mode trunk

Here are the problem,

If i connect Finger Print Device to port catalyst 2960, some device not sending data to server, but if i connect all Finger Print to HUB and from HUB connect to Catalyst 2960 at port F0/5, All Device(Finger Print) can send data to server...

Is there any special configuration in catalyst so all device can direct connect to port catalyst 2960 without HUB?, if so can you give me some solution to make it happen

Thanks & Regards,

Ariyanto

Do the servers pull an address off the network or are they hardcoded addresses ?  If they are pulling an address then on all  server ports add  the following command , "switchport host " .  See if that helps at all . Sounds like a spanning tree issue .

hi glen,

thanks for your info... i add with switchport host each port on catalyst whiches connected to finger print.... until now the server can receive data from finger print

Hi Ariyanto,

    Are you able to provide show vlan and show interface trunk outputs for both switches? Thanks
