Configure vlans cisco switch Pc#

Therefore, you must use Telnet to configure the Switch with a remote connection from a PC on the network. When configuring the Switch for the first time, we usually connect and configure a computer. In this topology, we have used the Layer 3 Switch, which works in the Network layer of the OSI layer. Afterwards, create a topology as in the image below. So, this is how you can configure VLAN in Cisco Catalyst Swtich.First, run the GNS3 program, and create a new project.

Most popular form of VLAN routing is router on a stick. You need a router to make communication occur between two VLANs. You can ping another PC within same VLAN but not to another VLAN. Trunking Native Mode VLAN: 1 (default) means the native VLAN is 1 and itвЂ™s the default behavior. Negotiation of trunking: on means the DTP (Dynamic Trunking Protocol) is on. Operational trunking encapsulatioin: dot1q means the trunking protocol running is dot1q. Administrative trunking encapsulation: dot1q means the encapsulation is set to dot1q. Operational mode: trunk means the port is trunking. Administrative mode:trunk means, we manually specified the port as trunk. Switchport:enabled means the port is working as layer 2 port, not layer 3. The above command shows lot of details of interface fa0/6.

Vlans allowed and active in management domain means, VLAN 1,2 and 3 have been created in this switch and are active. Vlans allowed on trunk is 1 to 1005, this means 1 to 1005В VLAN IDs can pass through thisВ trunk. Port Vlans in spanning tree forwarding state and not prunedДЄs you can see above, interface fa0/6 status is trunking, native vlan is 1 and encapsulation is 802.1Q.

Port Vlans allowed and active in management domain Port Mode Encapsulation Status Native vlan To verify the trunk port you can use command show interfaces trunk. The command above configured port fa0/6 as TRUNK port and the encapsulation protocol is dot1q. %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/6, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/6, changed state to down Switch1(config-if)#switchport trunk encapsulation dot1q You can repeat exact same steps on Switch2 as well.В Now, letвЂ™s configure TRUNK ports starting with Switch1. VLAN Type SAID MTU Parent RingNo BridgeNo Stp BrdgMode Trans1 Trans2ДЄs you can see above, ports fa0/3 and fa0/4 are in VLAN2 and ports fa0/1 and fa0/5 are on VLAN3. Switch1#show vlanДЎ default active Fa0/2, Fa0/6, Fa0/7, Fa0/8 To verify if VLANs have been created, use show vlan command as shown below. Switch1(config-if-range)#switchport access vlan 2 Switch1(config-if-range)#switchport mode access Switch1(config)#interface range fastEthernet 0/3 - 4 To assign multiple interfaces at a time we use interface range command as shown below for VLAN 2. Switch1(config-if)#switchport access vlan 3 Switch1(config-if)#switchport mode access
