Hey together,
I bought some WS-C2960X-48LPS-L & WS-C2960X-24PS-L running 15.2(2)E7.
I built a default configuration for each type of model.
Amongst other things, I configured vlan 101 to use it for mgt stuff via usual uplink. Of course I configured interface vlan 101 with an IP address, trunk ports and a default-gateway.
I configured new devices with the default config, while I was updating the variables like hostname, IP address and many more.
Management vlan (L2) config was in the default config as followed:
..
vlan 101
name xxx
..
Today I installed some of these switches and I was wondering that the configuration of L2 Vlan isn't working.
As I checked the config I saw, that interface vlan 101 was configured while vlan 101 wasn't configured.
So I configured vlan 101 again and it worked. As I checked the running-config again, I missed the vlan config again but as mentioned it was configured.
Did anyone of you, faced the same issue and if yes, do you know whats wrong?
I already built such default configs for a huge list of models and I've never faced something like that.
Why the hack is the configuration ignoring the layer 2 vlan config?
Again, I expect "vlan 101", "name xxx" in the config, but it is not there.
It is also still not there if, I add it it again, manually.
If I do "show running config" on one of my Nexus 5548up for example, I see these expected vlan config statements, but not on these 2960x..
I have no explanation and I don't understand this behavior.
Hopefully you guys have an idea. :D
cheers Tim

Thanks Diana, you gave me the hint :D
Forgot to configure vtp mode transparent which was the reason why vlan config wasn't shown in the running config.

Hello Tim!
Can you see the vlan when you do a "show vlan"? how is your VTP configured?
Do not forget to rate useful post.
