Cisco-vlan Configuration

Tag: mode command using log ENC Global relay name configuration

Switch interface type:

1. Access: Access mode, PC via switch internet this way
2. Trunk: Trunk mode, inter-switch connection in this way

Switch VLAN creation mode:

1. Database configuration mode
2. Global configuration Mode

Database configuration mode:

 - name Vlan20 (VLAN name optional) switch (VLAN) #exit

Global configuration mode:

 - switch (config-vlan) #name vlan20 (VLAN name optional) switch (config-vlan) #exit

Switch VLAN Removal method:

When configured in VLAN database configuration mode, the VLAN that needs to be deleted can be removed via switch (VLAN) #no VLAN (the ID of the specific VLAN) .

You can also delete VLANs directly in global configuration mode, such as switch (config) #ｎｏ VLAN

Add the switch interface to the VLAN:

• Adding VLANs on a per-interface basis
• Configure multiple interfaces to join VLANs at the same time

Add VLANs one by one:

# Add interface to vlan,access mode: switch#config tswitch (config) #interface F0/1switch (config-if  ) #switchport mode accessswitch (config-if  ) #exit # Connect between switches using Trunk mode: Switch (config) # interface F0/1(interface connected to another switch) switch (config- if) #switchport Mode Trunk

Multiple interfaces are configured simultaneously:

Switch (config) #int range f0/15  switch (config-if) #switchport Mode Accessswitch (config-if)switch (config-if

To remove an interface from the VLAN:

Other VLAN commands:

• Show VLAN Brief
• Switch (config) #switchport trunk encapsulation{isl|dotiq|negotiate} (requires a package type to connect to different brand switches)
• Switch (config-if) #switchport trunk allowed VLAN remove Vlan-id (relay mode does not transmit data from a VLAN)
