Access Port Communication

[vidyagov]

Hi Team,

Need your expertise.

Is it possible to have communication between differnt PC?
I have configured 2 SVI on ESW1 and ESW2.
vlan 10= ip 10.1.1.100
vlan 20= ip 10.1.1.200
I am to ping from PC1 to PC4 but not with any other PC. How is this possible. Ideally none of the pings should work.

Please refer the attached diagram.

You need to have different subnet for different VLAN, you can not have same IP address network.

Example : 10.1.1.x/24 for VLAN10 and 10.1.2.x/24 for VLAN 20

you can also have same over lap IP address in different network ( but you need to do NAT to communicate each other)

in your case you can extend the VLAN 10 use all same IP address range. ( bringe the PC2 and PC4 to same VLAN Access Group)

Between ESW1 and ESW2 you always need to be use Trunk and allow VLAN 10 and 20, it can not be Access port if you like to pass more VLAN across Switches.
