HI
Got a spare switch which I want to put into the network. Current setup is only VLan 1 and no other vlan.
pix(FW)-----3750---C4k
sjcswextdmz01>sh vtp stat
VTP Version : 2
Configuration Revision : 0
Maximum VLANs supported locally : 1005
Number of existing VLANs : 5
VTP Operating Mode : Server
VTP Domain Name :
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
MD5 digest : 0x57 0xCD 0x40 0x65 0x63 0x59 0x47 0xBD
Configuration last modified by 0.0.0.0 at 0-0-00 00:00:00
Local updater ID is 192.168.8.10 on interface Vl1 (lowest numbered VLAN interface found)
I assume I can just put in the other switch and:
1. do a "wr er"
2. reconfigure in transparent mode
3. setup the trunk btwn both switch
The reason for this is the 3750 is limited to 2 span ports which are currently being used so I need an additional span. My concern is how this may effect the c4k which I no access to as this is manage by another group:

I assume the setup you have shown is your current one. Where exactly are you going to put this new switch in the setup.

I will attach another 3750 to the current 3750.

I understand that you have only one switch currently and want to add new one.
If you want to create vlan in addition to vlan0 then you need to create trunk using these commands on 3750
int g1/0/23 (or whatever is interface)
switchport trunk encapsulation dot1q
switchport mode trunk
Same on other switch
For configuring VTP domain
as your first switch is in VTP server mode
I suggest you add second switch to client mode instead of transparent mode
Later after creating VLANs you can add port to these desired VLAN using following command
switchport access VLAN number
