[yong khang NG]

Hi all,

Facing some issue on Cisco catalyst switch SmartInstall.

A. Below is the log of debug vstack, taken from director switch:

B. Snipet of director switch config as below

config tftp://10.10.1.2/24TS/C2960S24TS_config.txt

match WS-C2960S-24TS-L

file-server 10.10.1.2

default-router 10.10.1.1

!

vstack director 10.10.1.1

vstack basic

Question

1. What happen to director switch DHCP, why there's no IP DHCP assign to the VStack client?

2. What need to prefix on the client config file (C2960S24TS_config.txt), example should i put no shut on int vlan 1? anything need to mention?

thanks

Hi eugen,

I no shut on int vlan 1, but still no go.

Any more item i need to look into the client config template? Thanks in advance

I have a strange feeling your "image file" is missing or named incorrectly.

Attached is my working "ZeroTouch for Dummies".  Have a look-see and let us know.

match WS-C2960S-24TS-L

One more thing, you DO NOT need this.

What is the IOS is the director running?

Hi leolaohoo,

Thanks for reply and ur zero-touch doc is great !!!!!

Somehow i manage to solve the client switch issue,  where director switch able to provision the config file, image file and  imagelist.txt to the client switch. Eveyrthing happen like written at  your doc.

OK, how i overcome previous issue. I issue 3 command  on the config template: no shut on int vlan 1 and ip address dhcp,  vstack director IP.IP.IP.IP (point to the director). Then it just work  !!

Well, some question need more clarification

1. I found the client switch finish loading, it will  auto reboot.After reboot I cannot see any changes on the client switch  startup and running config. The difference after reboot found on the  config file were the there's selfsign certificate, and

vstack director IP.IP.IP.IP, no change on hostname and etc.

2. anything need to mention or pre-config on the configuration file that load from director to client switch?

Thanks

[Leo Laohoo]

My "config" file contains the "template" of the common configs that will be found in my switch.  An example of the "template" configurations will be my MACROS, my username/password, timezone configs, snmp server and community.

Hi leolaohoo,

Thanks for the reply. Any template can let me reference with? still stuck with the client switch cannot get its update (example: no new hostname assign it to the client switch)

thanks

Hi Noel,

I'm not at the office right now.  I'll check the files I have on Monday.  You're after the configuration template, is that correct?

[yong khang NG]

yup,

Just take it as a reference material.

Have a nice weekend sir, chill

Oh, if that is the case, it's just the most-common configuration lines you'll need.  For example:

1.  TACACS/RADIUS;

2.  MOTD;

3.  Timezones;

4.  MLS QoS;

5.  Switchport Macros (hidden command);

6.  SNMP community;

7.  SNMP traps;

8.  Remote and Local login details;

9.  Syslog details.

So what happens is when the new switch downloads the configuration 'template" (which contains the items listed above), and downloads the IOS of my choice, all one has to do is enter the "unique" details:

1.  Management IP Address;

2.  SNMP details;

3.  Banners;

4.  Port assignments based on Switchport Macros
