Hi, there I was tasked with Migrating the VLANs from s cisco Catalyst 2960-X to a Meraki MX86 Firewall and I wonder if I can get some assistance as I'm not super familiar with Cisco Switches,
here are the VLANs to migrate
interface Vlan10
description Servers
ip address 192.168.10.10 255.255.255.0
!
interface Vlan12
description Data/PC
ip address 192.168.12.10 255.255.255.0
ip helper-address 192.168.10.24
!
interface Vlan14
description Voice
ip address 192.168.14.10 255.255.255.0
ip helper-address 192.168.10.24
!
interface Vlan16
description SOT
ip address 192.168.16.10 255.255.255.0
ip helper-address 192.168.10.24
!
interface Vlan18
description Box
ip address 192.168.18.10 255.255.255.0
ip helper-address 192.168.10.24
and currently, there are Static routs St on the Meraki for the subnets of VLAN 12-16 and are pointing back to the Switch. and all is working
I try to move VLAN 18 and it did not work, and I'm sure that I did something Wrong.
Here is what I did:
I started by removing the Vlan interface from the Switch with the following command:
No interface Vlan18
and then Remove the Static Route on the Meraki FIrewall.
then Create the new VLAN on the Meraki and I set everything to be the same:
Vlan18
ip address 192.168.18.10
and the DHCP I set it to not respond to DHCP request which will forward the request to the Server
192.168.10.24
then I made sure that the port connected from the Meraki to the Switch was set to Trunk and the VLANs allow set to "all" as there are other VLANs on the Meraki.
the Native VLAN setting on the trunk is set to "drop Untagged Traffic" ( this is on the Meraki MX86).
On the Cisco Switch here is the port Configuration that is connected to the Meraki
interface GigabitEthernet1/0/1
description Uplink to Meraki M7
switchport trunk allowed vlan 10,12,14,16,18,40,45,50,55,775,777,778
switchport mode trunk
srr-queue bandwidth share 1 30 35 5
priority-queue out
mls qos trust cos
auto qos trust
spanning-tree portfast
and when I finish with the Configuration nothing Work on this subnet ( VLAN 18).
then I reverted the Change and everything work again.
I need some help to figure out how to do this properly as I clearly failed.
Thank you in advance.
