I did a complete switch config, VLANs and all, and TFTPd the config out to a server. Then I cleared the switch out (delete vlan.dat and wri era/reload). Once it reloaded I configured the minimum necessary to get IP connectivity to the TFTP server, and did a copy tftp run. The copy was successful and everything was right...expect that no VLAN.DAT was created.
I assumed that when the switch parsed the confg file, as an interface was configured for access to a VLAN, that particular VLAN would be created. But that didn't happen.
I ran a SHO IP INT F0/2 and saw that the port was assigned to VLAN120 and it was (INACTIVE). SHO VLAN does NOT show VLAN120 in any way (active or suspended).
So why doesn't the switch create the VLAN.DAT while parsing the config? or does it, but something is missing so the VLAN is inactive instead of...active?
Tried this on two 3560s, one running IPSVCS-K9 and the other running IPBASE. Same results on both.
Thanks for any insight!
