pinging request timed out

[tayyib844]

Hello

I'm currently struggling trying to ping my devices but I keep on getting request timed out it only works when i ping the devices on the same VLAN all the devices are connected with dhcp and they are getting the ip addresses but they cant seem to ping together. I can ping to the layer 3 switch just fine its just with the end devices on the different VLAN any suggestions.

Hello @tayyib844 

Add ip routing command on your L3 switch.

ip routing is already enabled so I need to enable it on every interface

1. Confirm VLAN Setup: Make sure each VLAN is correctly configured on your switch.
2. Enable IP Routing: Check that IP routing is active on your layer 3 switch to allow VLANs to talk to each other.
3. Check Subnet Masks: Ensure that all devices have the correct subnet masks and gateways, typically the IP of the VLAN interface on your layer 3 switch.
4. Review DHCP Settings: Double-check your DHCP settings to ensure they're assigning the right gateway and subnet.
5. Inspect Security Rules: Look for any firewall or security settings that might block ICMP (ping) across VLANs.
6. Try a Static IP: Temporarily set a static IP in one VLAN and try pinging it from another to see if DHCP might be the issue.

Going through these steps should help you pinpoint and fix the problem so your devices can communicate smoothly across different VLANs.
