VLAN incorrecly removed on 2960S, then recreated, NIC still can't connect

Hello,

I have a CISCO 2960S with two VLANs. One of the VLANs (VLAN 16) was removed by accident, following incorrect instructions from some old documentation. VLAN 16 was recreated and is now active and the protocol is up. There are about 32 ports with "switchport access vlan 16." Traffic pass through as long as the user workstation's NIC is not setup with VLAN 16. I had to remove VLAN 16 on 32 workstations so that they could access the network. As soon as I set the user's NIC with VLAN 16 I can't ping other stations or servers on the network.

The VLAN shows up when I do "sh vlan" with all ports.

 

I am definitely not an expert in CISCO switches. I went through several discussions and posts on the net but couldn't find an answer that would apply to my issue. I am not sure what I am missing. Possibly someone ran into a similar issue and figured out why the VLAN is not working for users connected to that switch, even though all seem fine on the switch side.

 

I would appreciate some guidance. Let me know if you need additional information.

@rlem Hello,

 

Please, input your configuration here: show running-config 

 

By the way, input the commands below:

 

sw(config): interface range gi1/0/1 - 32

sw(config-if): switchport mode access

sw(config-if): switchport access vlan 16

 

sw(config): vlan 16

sw(config): interface vlan 16

sw(config-if): no shutdown

 

Post here: 

show interfaces trunk

show ip int brief

show vlan brief

 

Thanks in advance
