can't ping the new ip address

[lejiajing1208]

Hello,everyone

I am dealing with SG300-10 switch. I am trying to assign a ip address for a new VLAN ID. But I can't ping it after I finished.

First, I added a new VLAN ID(100)

Then I assigned a port to that vlan

Finally, I added a ip address for that vlan id

After that, I tried to ping 192.168.10.24, but it was not working.

Is there anything wrong I did?

Hi Jiang, if there is no active connection in VLAN 100 it will not work. Conversely, if no active connection in VLAN 1 it also will not work.

Hi Tom. I am sure there is an active connection in VLAN 100.

Alright, 2 scenarios.

Scenario 1-

Host A is connecting to the switch on VLAN 1 with IP address 192.168.1.10 255.255.255.0 with gateway 192.168.1.254. While there is an active connection on VLAN 100, Host A should be able to pnig 192.168.1.254 AND 192.168.10.254

Scenario 2-

Hostt B is connecting to the swith on VLAN 100 with IP address 192.168.10.10 255.255.255.0 with gateway 192.168.10.254. Host B should be able to ping the VLAN 100 SVI at 192.168.10.254.

I am not sure what's wrong with it. I assign port1 to vlan 1 with ip address 192.168.1.254. Then I connect laptop A to port1. I also assign port2 to vlan 200 with ip address 192.168.2.254.  Also I connect laptop B to port2. I am in layer3 mode now.

Port1 is in Trunk mode and port 2 is in General mode. I can ping 192.168.1.254 on laptop A. But I can't ping 192.168.2.254 on laptop B.

Hi Jiahing, you're giving too many omissions. Everything about the VLAN's, IP addresses, gateways, physical connection and firewalls matter.

This is how to configure everything to get basic connectivity.

Host A connects to port 1 on VLAN 1.

Host A IP address will be 192.168.1.10 with mask 255.255.255.0 with gateway 192.168.1.254

Host B connects to port 2 on VLAN 200

Host B IP address will be 192.168.2.10 with mask 255.255.255.0 with gateway 192.168.2.254

The switch configuration would be as follow-

config t

vlan database

vlan 200

int vlan 1

ip address 192.168.1.254 /24

int vlan 200

ip address 192.168.2.254 /24

int gi0/2

switchport trunk native vlan 200
