Inter-Vlan communication issue in 3850 cisco switch

‎05-28-2019 02:56 AM

I have 4 location in the company. I am using the 3850 Cisco switch in one location of my company and that location is mediatory for other 3 location also. I am using the same 192.168.0.x subnet for 3 location & one location using 172.16.15.x subnet and connectivity between all units are working through RF. I created two VLAN (VLAN 10 & VLAN 20) on one 3850 cisco switch. In VLAN 10 my all RF connectivity is existing and I am able to connect any machine/device of any location of my company and also I am able to connect with VLAN 20's machine. but I am not able to connect with VLAN 10's machine from Vlan20's Machine. Gateway of VLAN 10 is pinging in VLAN 20's machine.

 

IP Routing command is enabled in the switch. but still, I am not able to understand that, why I am not able to ping any machine of VLAN 10 from VLAN 20's machine.

My main motive for creating the VLAN for controlling the broadcasting. Is there any other way to control the broadcasting in 3850 switch?

Hello,

 

-->  am using the same 192.168.0.x subnet for 3 location & one location using 172.16.15.x subnet and connectivity between all units are working through RF.

 

I can only see two VLAN interfaces in your configuration:

 

interface Vlan10
ip address 192.168.0.178 255.255.255.0
!
interface Vlan20
ip address 192.168.10.1 255.255.255.0

 

How is the 172.x.x.x subnet involved here ? So basically you are saying that 192.168.10.0/24 cannot reach anything on 192.168.0.0/24 ? What is the IP address of the device(s) connected to:

 

interface GigabitEthernet1/0/7
switchport access vlan 20
switchport mode access
!
interface GigabitEthernet1/0/8
switchport access vlan 20
switchport mode access

switchport mode access

 

IP Address:- 192.168.10.123

Subnet:- 255.255.255.0

Gateway:-192.168.10.1

Hii Georg Pauwen, 

 

have you found any error in configuration? or Is there any solution to resolve my issue? So that I can stop the broadcasting in the Cisco switch.
