Vtp database not updating
If a VLAN is not known to a switch, that switch cannot transfer traffic across any of its ports for that VLAN.VLANs are created by number, and there are two ranges of usable VLAN numbers (normal range 11000 and extended range 10254096).
I recently replaced the switch that was functioning as the VLAN server for the rest of the network.
Let’s see if we are able to synchronize some VLANs.
We’ll start with something simple: No problem at all! VTP version 3 is able to synchronize private VLAN information.
VLANs are created using the set vlan command for COS devices or with the vlan command in vlan database mode for IOS switches.
For Ethernet VLANs, you can also configure the standard parameters in Table 6-1.
