Uplinking a Cisco 3560 Switch

I am fairly new to switching so I am just doing this in a test environment to teach myself some things. I am trying to uplink a cisco 3560 switch from another 3560 switch. I have it linked and I can plug in a laptop to the switch and get out to the internet but I am unable to ping the switch, telnet, or ping from the switch. It shows that VLAN2 is down but I am not sure why. I have VLAN1 administratively down and should be using VLAN2. What am I missing with the setup? Please let me know what other configurations you need.

The uplink port is configured like this:

switchport trunk encapsulation dot1q
switchport mode trunk
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2
mls qos trust cos
auto qos voip trust

The port that it is being uplinked from is configured like this:

switchport trunk encapsulation dot1q
switchport mode trunk

Thank you!

Did you setup VTP on the main switch?

The main switch should be the VTP server and the second switch should be the VTP client.

If they are on VTP transparent mode, then you need the same VLANs on each switch.

sh vtp status will tell you.

Yes.

can you post "sh run"?

According to your output, you are uplinking this interface :

interface GigabitEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2
mls qos trust cos
auto qos voip trust

The interface on the other should be configured the same as well.

Can you also do "sh vtp status" from both switches and also "sh vlan brief" from both switches?

You also need to assign any interface to vlan 2 in order to bring the vlan up.

interface fa0/10
switchport access vlan 2

I would change the spare switch VTP to transparent and make it to client again mainly because it has higher revision number.

You should run "sh vtp password" to make sure you have set the same password on the spare switch.

Also change the VTP version to 2 on the spare switch.

I have them both named as spare switches for testing. Can you specify which one you're referring to.

The switch I am trying to uplink is spare3 and the main switch is just spare.

No worries.
You da man, there was a password set on the main switch but not on the other one. As soon as I changed it then vlan2 came up and I was able to ping to and from the switch.

Thank you very much.

Infamus

Glad it worked out.
