Switch Trunk port configuration

This article is for forwarding, simple and clear, I like.

The configuration steps for Trunk ports are as follows:

A set of network requirements:

1. SwitchA and SwitchB with trunk interconnection, the same VLAN between the PC can exchange visits, different VLANs between the PC to prohibit mutual visits;

2. Between PC1 and PC2 in different VLANs, by setting the upper layer three switch SwitchB VLAN interface 10 IP address for 10.1.1.254/24,vlan interface 20 IP address for 20.1.1.254/24 can achieve inter-VLAN visits.

Two-group Network diagram:

1. Intra-VLAN visits, inter-VLAN exclusion

2. Inter-VLAN visits via three-layer switches

Three configuration steps:

SwitchA Related configurations:

1. 1． Create (Enter) VLAN10 and e0/1 Add to VLAN10 [Switcha]vlanTen[SwitchA-vlan10]port Ethernet0/1   2． Create (Enter) VLAN20 and e0/2 Add to VLAN20 [Switcha]vlan -[SwitchA-vlan20]port Ethernet0/2   3． G1/the port1 configured as Trunk port and allows VLAN10 and VLAN20 to pass [SwitchA]InterfaceGigabitethernet1/1[SwitchA-gigabitethernet1/1]port link-type trunk [SwitchA-gigabitethernet1/1]port Trunk Permit VLANTen  -  

SwitchB Related configurations:

1. 1． Create (Enter) VLAN10 and e0/10 Add to VLAN10 [Switchb]vlanTen[SwitchB-vlan10]port Ethernet0/Ten     2． Create (Enter) VLAN20 and e0/20 Add to VLAN20 [Switchb]vlan -[SwitchB-vlan20]port Ethernet0/ -     3． Configure Port G1/1 as Trunk port and allow VLAN10 and VLAN20 to pass

SwitchA Related configurations:

1． Create (Enter) VLAN10 and e0/1 Add to VLAN10 [Switcha]vlanTen[SwitchA-vlan10]port Ethernet0/1    2． Create (Enter) VLAN20 and e0/2 Add to VLAN20 [Switcha]vlan -[SwitchA-vlan20]port Ethernet0/2  3． Configure Port G1/1 as Trunk port and allow VLAN10 and VLAN20 to pass

SwitchB Related configurations:

1. Create VLAN10 [Switchb]vlanTen   2. Set the virtual interface address of the VLAN10 [SwitchB]InterfaceVlanTen[SwitchB-int-vlan10]ip Address10.1.1.254 255.255.255.0   3. Create VLAN20 [Switchb]vlan -   4. Set the virtual interface address of the VLAN20 [SwitchB]InterfaceVlan -[SwitchB-int-vlan20]ip Address20.1.1.254 255.255.255.0   5． G1/the port1 configured as Trunk port and allows VLAN10 and VLAN20 to pass [SwitchA]InterfaceGigabitethernet1/1[SwitchA-gigabitethernet1/1]port link-type trunk [SwitchA-gigabitethernet1/1]port Trunk Permit VLANTen  - 

The configuration of the trunk port in the VLAN is over, I hope you have mastered it.
