Hello guys, I am new to Cisco. Please help me.
1. I have a Cisco Core Switch: Vlan 1: 199.164.42.1, Vlan 14: 172.25.48.1
2. Then, I have a switch 199.164.42.9 with the following:
Port 5 is mainly used for manually configured devices on Vlan14.
Port 7 is a test port.
3. Using my laptop through Port 7 I am able to connect by using a static IP address:
IP: 199.164.42.200
Subnet: 255.255.255.0
Default Gateway: 199.164.42.1
DNS: 199.164.42.14
DNS: 8.8.8.8
4. Using the same config on my laptop I am not able to connect through Port 5.
Also please check ports mode:
I cannot understand why. Thank you very much!
After I understood the issue, I was able finally to add the Vlan 1 to port Gi0/5
By using following commands:
#configure
#interface range gi0/5
#switchport mode access
#switchport access vlan 1
#no shut
#exit
The result:
#show vlan
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Gi0/5, Gi0/8, Gi0/9, Gi0/10
Gi0/11, Gi0/12, Gi0/13, Gi0/14
Gi0/18, Gi0/19, Gi0/20, Gi0/22
As it works on my laptop, tomorrow will do a live test, will connect a device that it was not working before. Hope it does.
Anyone to help, I got confused and stopped here:
Still cannot ping 199.164.42.1 on VLAN1.
Here is what port 5 looks like:
#show interfaces trunk
Port Mode Encapsulation Status Native vlan
Gi0/5 on 802.1q trunking 14
#show vlan br
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Gi0/8, Gi0/9, Gi0/10, Gi0/11, Gi0/12, Gi0/14, Gi0/18, Gi0/19
Gi0/20, Gi0/22
My last try was:
I read about mode dynamic auto, which allows the port to be either trunked or static.
(config-if-range)#switchport mode dynamic auto
Result:
#show interfaces trunk
Port Mode Encapsulation Status Native vlan
Gi0/5 auto 802.1q trunking 14
Port Vlans allowed on trunk
Gi0/5 1,14,100
Also I was able to ping both VLANS: 1 and 14 !!!! which is very nice !!
