3120X-S not able to route outside

aititsupport

Level 1

I'm not really sure why or what has changed.   We have a 3120X-S that is not able to reach anything outside its network but external sources are able to reach the file share that resides on the blade.  Here is the config information:

#sh ip route
Default gateway is 10.15.1.25

Host Gateway Last Use Total Uses Interface
10.8.8.89 10.15.1.2 0:01 32382 Vlan100

 

The 10.8.8.89 doesn't even reside on the switch and is using the wrong gateway.  I have tried to remove it, but its not built into the CLI so it errors out.  The new gateway is 10.15.1.8.   I can ping the gateway and other resources locally but nothing externally.

 

 

#ping 10.15.1.8
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.15.1.8, timeout is 2 seconds:

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.8.1.1, timeout is 2 seconds:

I wouldn't be to worried but I am not able to remote (SSH or Telnet) without going through our core switch.

 

Thoughts?

ip default-gateway 10.15.1.25

ip default-gateway 10.15.1.x

The ip default gateway is incorrect. It needs to be the next hop ip and not the ip from the SVI.

Thank, I don't know how I missed that.
