assigning switch ports to switch in cisco.

[ahmadqayyum7]

In the diagram below how will I assign switch ports to Switch 1?

If you want the ports as access ports:

# interface fastethernet [interface number]

# switchport mode access

# switchport access vlan [vlan number]

If you want the ports as trunk ports:

# interface fastethernet [interface number]

# switchport mode trunk

# switchport trunk allowed vlan [vlan numbers]

one more thing. when configuring trunking mode will i give the same interface ranges on all switches?

Hi  @ahmadqayyum7 ,

When you configure an interface as a trunk, you can leave by default to allow the passage of all the vlan:

Switch(config)#interface f0/1

Switch(config-if)#switchport mode trunk

or select what vlan you will allow:

Switch(config)#interface f0/1

Switch(config-if)#switchport mode trunk

Switch(config-if)#switchport trunk allowed vlan <vlan range>

Obviously, the allowed vlan range must be the same at both ends of the link.
