Hi Giuseppe,

Thansk for your reply, and much appreciate your help..you're a start and always help me..

yes switch2 was part of stack ages ago, but its a standalone now and still showing Gagetherx/x/x, can I resolve this issue?

Can I make switch 1 as a vtp server instead of switch 2?

any idea about my other questions?

1- is rest of the config OK?

2- do I need to do any thing specific for 3750 fast ethernet and Gagbit ethernet trunks point of view or VLAN point of view or normal config will work ???

3- ip helper address command will take 3 ips for 3 dhcp servers or not?

Please could you answer all the questions if possibel please.?

Hello Sohail,

3) you need three distinct lines for helper address one for each server

or you can use the directed broadcast if the three servers are in the same IP subnet

1) yes

2) nothing special is needed I think unless you want to do an etherchannel for connecting switch2 to two ports in two different stack members.

this can be seen as a meaningful improvement

I would suggest LACP bundles

channel-group x mode active

all member links have to be configured in the same way.

about VTP: you can configure BOTH as VTP servers

about numbering of interfaces I will look

something like

switch member 1

could work

(to be checked)

Hope to help

Giuseppe

Hi Giuseppe,

Thank You so much for your support, I am almost there now to digest everything you suggest, can you give me favor please, DHCP servers are in same subnet can you tell me what will be the command for the the directed broadcast please,

I'll configure both switches as a vtp server, and for the switch as per my understanding I only need to do 2 things:

vtp mode server

int gint f0/0/0

switchport mode trunk

switchport trunk encap dot1q

and that's it ..I am done (I hope)??

finally last question: in switch2's config

spanning-tree mode pvst

spanning-tree extend system-id

vlan internal allocation policy ascending

is it something I need to look at??will it not give me any problem?

I know i need lots of study but guys like you always help people like us when needed...

Regards

Hello Jag,

if the subnet is 10.10.10./24 the directed broadcast is 10.10.10.255

it is the last address in subnet that with all 1s in the host part.

>> spanning-tree mode pvst

spanning-tree extend system-id

vlan internal allocation policy ascending

these should be defaults

spanning-tree extend system-id:

causes STP bridge id to be made of:

base priority + Vlan#

the stack may have an older IOS where this is not enabled

Hope to help

Giuseppe

Thank you soo much Giuseppe,

This all make sense now. God Bless you.

I might nudge you again if I find any diffculty, :-)

Thanks Again.

Hi Giuseppe,

How are you, further to our discussion I am having dificuties and I thought to nudge you again for help.

I am attaching my current and proposed diagram for new VLANs, which we agreed. But our service provider is not agree with this, as you see the diagram,  they are proposing to create a link between leeds router which is currently 10.6.1.0/24 to 172.16.2.1/30 where 172.16.2.1 will be assign on router interface and 172.16.2.2 on switch intrface, delete routes for the onsite firewall from the router and place these routes in the 3750 switch which is currently working on default vlan with IP 10.6.1.10.

As per Service Provider we cannot add routes in the router for the MPLS or i actually missunderstand what he was saying and trying to convince me to add all routes in the switch.

I was thinking is it a good practise to do this as they are saying. or force them to add routes for new vlans on the mpls cloude.

is this all making any sense to you?

if yes then please could you give me any example?..if we agreed to service provider...please include voice traffic also in the scenario..
