Unable to find VTP configuration

[melsayeh]

Hello,

Sorry if my question sounds obvious, but it is really weird to me, I have a switch running as VTP server, however, I can't find any config related to VTP in the running-config:

switch_name#show vtp status
VTP Version capable             : 1 to 3
VTP version running             : 3
VTP Domain Name                 : Domain_name
VTP Pruning Mode                : Disabled
VTP Traps Generation            : Enabled
Device ID                       : 0056.2bd9.1800

Feature VLAN:
--------------
VTP Operating Mode                : Primary Server
Number of existing VLANs          : 70
Number of existing extended VLANs : 6
Maximum VLANs supported locally   : 4096
Configuration Revision            : 12
Primary ID                        : 0056.2bd9.7777
Primary Description               : switch_name
MD5 digest                        : 0x3E 0xFB 0x53 0x82 0x03 0x94 0x6E 0x32
                                    0x79 0x05 0xC7 0x42 0x84 0xA9 0xA5 0xCD


Feature MST:
--------------
VTP Operating Mode                : Transparent


Feature UNKNOWN:
--------------
VTP Operating Mode                : Transparent

switch_name#show running-config | i vtp
switch_name#
switch_name#
switch_name#
switch_name#show startup-config | i vtp
switch_name#
switch_name#

Does this sound familiar?

you won't see any vtp config unless you are running in transparent mode. 

the caveat to that is I'm not sure of the differences across platforms, and you didn't say what platform this is.

Hi, thanks for your reply

This is Catalyst 3850, but I am still confused, What should I do to see the config or transfer the config script to another switch for example? 

[Joseph W. Doherty]

Normally, the expectation is, "transfer" to another switch would be via VTP update.  I.e. as the new switch joins an existing VTP domain.

Also, with what Martin mentioned about VTP transparent mode would also apply to VTP off mode (if supported on the device).

VTP Server or Clent mode configs are not saved in NVRAM so you will not see it in the running-config on Cisco switch. Those are saved in VLan.dat file on flash drive of a switch.

VTP transparent mode configs are saved there and those u will see in running-config. Change mode and do write then see it in show run.
