Cisco's basic configuration example of four----VLAN planning and configuration (access switch)

4.2 related configuration of access switches

# # In this example, we are connecting to an access switch where the GI0/1 port is allied to the core switch. It also means that we need to configure GI0/1 as trunk port. The specific configuration is as follows:

D-2960-3 (config) #int GI0/1

D-2960-3 (config-if) #sw

D-2960-3 (config-if) #switchport mo

D-2960-3 (config-if) #switchport mode?

Access Set trunking mode to ACCESS unconditionally

Dynamic Set trunking mode to dynamically negotiate access or trunk mode

Trunk Set trunking mode to TRUNK unconditionally

D-2960-3 (config-if) #switchport mode trunk

# # Configuration This interface mode is trunk, in the cisoc2960 switch, after configuring the interface mode trunk is available, do not need to further configure the package state of this trunk port, because its default is also the only package type is dot1q, And this series of switches does not have a dedicated package configuration command.

D-2960-3 (config-if) #exit

D-2960-3 (config) #exit

D-2960-3#sh int Tru # Fallback to privileged configuration mode verify the configuration you just made.

Port Mode encapsulation Status Native VLAN

GI0/1 Auto 802.1q trunking 1

# This port is already configured in trunk mode and is packaged in 802.1q

Port Vlans allowed on trunk

GI0/1 1-4094

Port Vlans allowed and active in management domain

GI0/1 1-2,10,20,30,40,50,60,70,80,100,110,120,150,160

Port Vlans in Spanning tree forwarding state and not pruned

GI0/1 1-2,10,20,30,40,50,60,70,80,100,110,120,150,160

D-2960-3 (config) #vtp mode client

# Configure the VTP mode to client, echoing the server mode of the core switch.

# #稍等一会后, verify that you have learned the VLAN information of the core switch, and that it learns a small part of the process for 30 seconds.

D-2960-3#sh VLAN # Verify that the VLAN information is all learned.
