L3 switch routing not working

farhadsultani

Dear all,

I have a catalyst 4500 series swtich version (cat4500e-UNIVERSAL-M), Version 03.08.01.E

I am connected to another L3 switch which conneting me to the internet and I name it internet_switch.

From the port which is directely connected to the internet_switch I am able to ping internet, but from other port which is connected to my pc (different subnet) and is routed port, I am not able to ping internet. 

 

ip routing is enabled, default route is configured on 4500 series switch, and also I have a static route towards my 4500 series switch  for my pc subnet.

Any one can help me solve this issue.

Thanks in advance.

General tshoot steps:

  • Check status of SVI for specific VLAN that you are testing (when host is plugged in port that belong to specific VLAN):
    • sh int status
    • sh ip int brief
  • Check routing table (are all routes present - including default route):
    • sh ip route
  • Check IP address and gateway configuration on host
    • ipconfig
  • Check your natting configuration on router are all subnets included in natting
  • Perform traceroute and/or ping from host to WAN interface to make sure that your local traffic is forwarded properly

ports are up, same senario working with other switches which are currentely in use, but not with this one. 


Maybe switch uses LAN base license?

sh license

sh license image level

Already tried Vlan too, not worked.

Hello,

is the other subnet included in the NAT statements which are configured on the switch that is directly connected to the Internet ?

Best and fastest way to resolve this is to post the configurations of both switches.

I am using public IP no need to use NAT, and using same scenario with other switches in my network all is working well. 
I think might be something with the 4500 series switch.

Hi there,

Could you possibly attach the configs of both switches for us to look at?

 

cheers,

Seb.
