VTP maximum VLAN number

We have a network with some cat4000 configured as VTP server

and several cat 2900/2950 configuired as VTP clients.

The cat 2900/2950 support a maximum of 68 VLANs and

we have 63 existing VLANs:

Maximum VLANs supported locally : 68

Number of existing VLANs : 63

What will happen when the number of existing VLAN will

be 69 or more ?

Thank you, best regards.

Re: VTP maximum VLAN number

I think, the switch would not allow you to configure a vlan number, when the count reaches 68. Other than that I dont see any other issues.

Re: VTP maximum VLAN number

I think Cat2900 supports only 64 STP instances.

If you create 65th VLAN, one of your VLANs (not necessarily the 65th) will be running without STP.

Milan
