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 WS-C3560X-24T-L  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.
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
 I meant to say spare3.

Only do "sh vtp password" on the main WS-C3560X-24T-S   switch to see if there's any password setup.

avaya ip office with Catalyst 3560

I have the following config for my switch

int gig0/1  through int gig0/20
WS-C3560X-48PF-S   switchport access vlan 10
  switchport voice vlan 20
The Avaya IP Office (PBX)  is doing the dhcp for the voip. vlan 10 has 10.10.40.0/24 subnet. vlan 20 has 10.10.45.0/24 subnet. My PCs are connected via the VoIP. The issue that I am having is I cannot ping the pbx from any of the PC. I can see its MAC address in the CAM table, Ip routing is enabled.

Each of the VLANs need to have an IP address configured (from the correct rage).

Also, the PCs needs to be set to have their default gateway pointing to the IP address of the switch.

Also, the PBX needs to have its default gateway pointing to the Cisco (or at least a static route for 10.10.40/24 with next hop being the cisco WS-C3560X-48PF-L).

You can check your set up on the switch with the "show ip route" command, to make sure it does have the relevant routes - once you have IP addresses in each VLAN.

Can you post a sanitized config from the switch?  Can the switch ping the VLAN default gateways and the PBX?
