Precision Time Protocol VLAN managment is quite different on ISR routers than on Catalyst switches. VLAN can be used as 802.1q subinterfaces for routed interfaces or with more switch-like configuration on Ethernet Switch Modules (HWIC-4ESW for example)
VLAN configuration (subinterface)
Coming soon
VLAN configuration (internal switch)
Router(config)#interface Vlan100
Router(config-if)#description mgmt
Router(config-if)#ip address 192.168.10.100 255.255.255.0
Router#vlan database
% Warning: It is recommended to configure VLAN from config mode,
as VLAN database mode is being deprecated. Please consult user
documentation for configuring VTP/VLAN in config mode.
