Basic 2960G configuration question

Hi all,

 

I'm new to cisco and I have a basic problem:

 

I have a 4506 switch and a new 2960G that I want to integrate to my network.

I configured the interface (the one that is linked to the 2960G) of my 4506 switch, as follow :

switchport mode trunk ecapsulation dot1q

switchport mode trunk

ip dhcp snooping trust

 

on the 2960G, I created the mgmt vlan:

interface Vlan10

   ip address 192.168.10.200 255.255.255.0

   no ip route-cache

ip default-gateway 192.168.10.1

 

and configure the interface that is linked to the 4506:

interface GigabitEthernet0/1

  switchport mode trunk

  ip dhcp snooping trust

 

However  I'm unable to ping my 2960G (commands like "show cdp neighbors" show that the link is up).

Can you help me ?

thanks in advance for your help.

Bruno

Is 192.168.10.1 the address

Is 192.168.10.1 the address that is configured on the 4500 for vlan 10 ?   check the masking etc to make sure it matches .   Did you create the layer 2 vlan for vlan 10 on the 2960 ? Verify with the show vlan command on the 2960.  On the 2960 it should show both vlan 1 and vlan 10  if it was created.

thanks Glen for your quick

thanks Glen for your quick answer.
You help me !
as soon as I created the vlan 10 on the 2960, I was able to ping it.
I didn't create it before because my switch was in vtp client mode.
I thought that the vlan 10 would be automatically created.
Now I have another question:
I'm always in vtp client mode but the following commands show that no vlan was got:

Should I have to force the vtp update process ?
