Practice LAB - help wanted

[Antony_85]

Hay guys,

Hope everyone is doing well.

I am trying out the following scenario in a lab environment but having trouble configuring.

VLAN 10 (Native) 172.16.10.0/24

DHCP server, Distribution switch and other 3 switched should be in this vlan (for management)

VLAN 20 ADMIN– 172.16.20.0/24

VLAN 30 CTM– 172.16.30.0/24

VLAN 40 SERVICE– 172.16.40.0/24

DHCP server is running separate pools for each network

PC’s must be able to talk to each vlan

I configured the VLANs in each switch and configured interfaces as follows

Distribution switch Gig 1/0/22 – 24 as trunk  (with VLAN 10,20,30,40)

Distribution switch Gig 1/0/1 – trunk (with VLAN 10,20,30,40)

Each switch

GigE 0/1 – Trunk (with VLAN 10,20,30,40)

Still not able talk to each other and unable to find a way to assign the network devices into 172.16.10.0 network.

Quick Look, high-level Cisco Default Native VLAN is 1 - Since you changing from Native VLAN 10, you need to specify the default native VLAN in the Trunk Config.

The picture is a bit blur here, is the DHCP also in Part of VLAN 10 ? do you have helper-address or DHCP snooping enabled?

To go deep if that has not solved the issue -  posting all the device config to verify ( show run)

Hi Again Balaji,

1. DHCP server works in vlan 1. I couldn't find a place to change the DHCP helper in the packet tracer. 

2. I didn't configure VLAN 10 as NATIVE in ADMIN, CTM, and SERVICE Switches. I will try this and update you. 

Thank you for the response.
