VTP problem

Hello guys, how are you doing?


I have a network like this:


SW-1        R1            SW-6
SW-2                  SW-7                  
SW-3     SW-Core      SW-8
SW-4                  SW-9
SW-5                  SW-10

I have 6 VLANS: 10-20-30-40-50-60

Every switch is connected to the other switch using GigabitEthernet

SW-1 is Connected to SW-2 with Gigabit1/1 Switchport mode trunk and same thing with all switches.

SW-5 is connected to SW-Core and then to SW-6

the rouer R1 is connected via fastEthernet to the SW-Core

I have set VLSM to give addressing for the the  Seven networks including the router.

The SW-Core has a VTP domain, VTP mode Server, VTP password. The other Switches are in VTP mode client.

The problem is, when i type a vlan is the SW-Core, the other switches do not receive the new update. why can this happen?

Check if all switches have the same domain name, VTP version is the same and VTP password is the same.
Also, VTP passes only through trunks. Check the status of your trunk ports and if they operate as trunks.

i need to know how to manage all the switches? should i create a new vlan and configure an adressing for all the switches? for exemple i create vlan 11 and i give every switch an adress like :
Switch1 : 10.10.10.1
Switch2 : 10.10.10.2
Switch3: 10.10.10.3

etc?

I'm talking about the management vlan to manage all the switches, no need to connect the console cable and then make a hard work
i did it
You can connect to any VLAN IP address on the switch either through telnet or ssh. It is a good security practice to setup a management VLAN and limit access to it.
I have set all IPs to the switches, now from the Core, when i type telnet 10.10.10.1 (to telnet the switch1)
it said [Connection to 10.10.10.1 closed by foreign host]  why?

Also, is there a way i can link the 10.10.10.1 with a name like SW1 ?? so when i type : telnet SW1 it takes me to the Switch1

Any idea?
Is it configured to only allow SSH?
I'm suing Packet Tracer you see?

Is the core switch set as Server or Transparent as the VTP mode?  The Core switch has to be set as server in order to pass vlan information to the attached client switches.  If the core is set as transparent, you can add vlan's to it, but it won't forward the information to the attached clients.
@topdavis, thank you, but i already have resolved this problem, now tell me is there a way i can link the 10.10.10.1 with a name like SW1 ?? so when i type : telnet SW1 it takes me to the Switch1??

@lrmoore: i'm just trying to figure out how to do this in packet tracer because i couldn't any idea?
You can set up DNS entries for the switch name and the corresponding IP address so on the PC you are telnetting from you can just use the DNS name.  You can edit the localhost file and put the corresponding names and ip address, but the telnet SW1 will only work on that machine with the modified localhost file.  DNs is a more universal solution if you have access to your DNS server.
If packet tracer is running a full IOS on the router, then these commands should be available to you to create the alias commands.
@lrmoore no it didnt work i think because as you said it is not a full IOS as i can see, it is basic and limited with few commands but i appreciate your help
thanks experts
