Please fallow my configuration and try

Router(config)#iint gigabit Ethernet 0/0/0 #no ip address #no shutdown

Router(config)# int gigabit Ethernet 0/0/0.10 #ip address x.x.x.x x.x.x.x #encapusation dot1q 10 #no shut`

Router(config)#int gigabit ethernet 0/0/0.20 #encapsulation dot1q 20 #ip address x.x.x.x x.xx.x #no shutdown

Router (config)#int gigabit ethernet 0/0/0.30 #encapsulation dot1q 30 #ip address x.x.x.x x.x.x.x #no shutdown

Router(config)# int gigabit Ethernet 0/0/0.40 #encapsulation dot1q 40 #ip address x.x.x.x x.x.x.x #no shutdown

Configure trunk Port in switch interface connectiing to router so that vlan 10, Vlan20, Vlan30,Vlan40 traffic will flow from router towards switch from this trunk Port

Switch(config)# int 0/1 #switch Port trunk #switch trunk allowed vlan all #no shutdown

Create access ports as per your requirements for example below

Switch (config)#int 0/2 #switchport mode access #switch Port access vlan10 #no shutdown /please connect this interface to end devices/

Create vlans in this switch

Switch(config)#vlan 10 #name finances

Switch(config)#vlan 20 #name account

Switch(config)#vlan30 #name operation

Switch(config)# Vlan40 #name hr

Try above configuration ....

Please follow my configuration and try

Router(config) #int gigabit Ethernet 0/0/0 #no ip address #no shutdown Router(config) #int gigabit Ethernet 0/0/0.10 #ip address x.x.x.x x.x.x.x #encapusation dot1q 10 #no shut Router(config) #int gigabit ethernet 0/0/0.20 #encapsulation dot1q 20 #ip address x.x.x.x x.xx.x #no shutdown Router (config) #int gigabit ethernet 0/0/0.30 #encapsulation dot1q 30 #ip address x.x.x.x x.x.x.x #no shutdown Router(config) #int gigabit Ethernet 0/0/0.40 #encapsulation dot1q 40 #ip address x.x.x.x x.x.x.x #no shutdown 

Configure the trunk Port in the switch interface connected to the router so that vlan 10, Vlan20, Vlan30, and Vlan40 traffic will flow from the router towards the switch from this trunk Port

Switch(config)# int 0/1 #switch Port trunk #switch trunk allowed vlan all #no shutdown` 

Create access ports as per your requirements, for example, below

Switch (config)#int 0/2 #switchport mode access #switch Port access vlan10 #no shutdown /*please connect this interface to end devices*/ 

Create VLANs in this switch

Switch(config) #vlan 10 #name finances Switch(config)#vlan 20 #name account Switch(config) #vlan30 #name operation Switch(config) #Vlan40 #name hr
