Why are 2 switchports with the same config getting IPs for different VLANs?
Using the same phone and pc on both ports
Ports 2 and 29 are configured the same in sh run
Port 2 gives a 10.1.1.x to phone and pc
Port 29 gives a 10.1.101.x to phone and pc
When doing a sh vlan brief port 2 is not associated with either vlan, and port 29 is associated with both vlans
According to cisco network assistant security is shut off on both ports

Check your DHCP settings. This can happen in several ways. A few things I can think of:
1. Port 2 isn't associated with the VLANs, while port 29 is, so they reach different DHCP servers. The DHCP servers have different configurations.
2. You have a group of DHCP servers, and one is configured with a different DHCP range. Your phone and PC are already associated with the respective servers, so they are granted the same IPs.
3. The port security / VLANs are different for the DHCP server connections.
3. Your configurations look the same in sh run, but either there is a detail missing, or they are configured differently upstream somewhere.
If you aren't finding much working from the client end, you may want to start with the DHCP servers they are getting a response from and work from that direction.
