VLAN IDs not showing up in 2960 switch configuration

We have Layer 2 2960 switches that all connect back to our 4500 core. the core has the Interface VLAN defs. But, in the access switches I can do a SHO VLAN and see all the VLANs in my network, but they do not show up in my running config. The guides all say to use the VLAN global command to define VLANs, but will just entering the switchport access vlan x put them in the VLAN database as well? We also do not have VTP defined. Any ideas?

Hello Kmattison,

>> but will just entering the switchport access vlan x put them in the VLAN database as well? 

yes this is correct. And it may explain what you see vlan entries in the vlan database without a corresponding vlan command in the running config.

 

Hope to help
