Urgent-Cisco Layer 3 Switch Configuration

Hi,

Since you have 2 segments (192.168.0.x and 192.168.1.x) you need to create 2 vlans on the switch.

Say vlan 10 is for the first segment and vlan 20 for the second segment. Than add the ports that connect to each statix to each vlan.

Also, see documents for config examples:

Thanks for your help Reza,

Basically I am an electrical engineer so my networks side aint that strong, I can configure ports for two hosts with fixed IPs say Host A is at IP 192.168.1.2 and Host B at 192.168.0.3. I can assign host A to gigabit port 4 suppose at VLAN 10 and ip address 192.168.1.2(fixed IP) and similarly host B to port 6 at VLAN 20 with IP 192.168.0.3.

But since Stratix switch cannot be assigned any IP and each stratix switch has multiple hosts with IPs 192.168.1.2, 192.168.1.3,192.168.1.4 and other stratix switch has hosts with IPs 192.168.0.3 and 192.168.0.4. Now in this case how will I configure port 4 and port 6 and what IP will I assign to these ports if VLANs assigned are 10 and 20 say??

Waiting for your reply, your kind help would be highly appreciated in this regard.

That is all correct.

Now in this case how will I configure port 4 and port 6 and what IP will I assign to these ports if VLANs assigned are 10 and 20 say??

From what you are describing the Stratix switches are simply layer-1 and so no need for IP or vlan. Another word, they work just like hubs and so in this case all you have to do is assign the correct IPs and gateways to the hosts connected to each Stratix device.

Hello,

Yes Stratix switch is a layer 1 switch or simply a hub, each hub has multiple hosts with same IP class, but tell me how would I configure my Cisco layer 3 switch ports for a hub?? What IP is to be assigned to ports as each hub has 3 hosts so which IP will be assigned to managed switch ports???

Please Help me out.

Regards
