Can't reach WEB UI when on WiFi

shoong

Hi Guys,

 

When I am on our internal WiFi, I'm unable to hit the NetApp Web UI. However, I can hit our other internal resources. Is there some sort of rule/restriction on the NetApp? Wireless or Hard Wired, I am on the same subnet.

Your client IP is 10.150.54.84 with a subnet mask of 255.255.252.0, or /22 - this means that according to your client, every IP within 10.150.52.1 to 10.150.55.254 is "local" - it can talk to it directly, no router needed.

 

Your NetApp system's cluster management LIF is 10.150.52.13, with a subnet mask of 255.255.255.0 or /24, which means according to the NetApp system, only IPs in 10.150.52.1-10.150.52.254 are local, everything else needs to go through a router. 

 

So in this configuration, your client is attempting to talk directly to the NetApp, but your NetApp will only talk to your client through a router.  Only one of these systems can be correct.

 

If you really have a /22 subnet, then the NetApp's configuration needs to be changed. If you only have a /24, then the client's configuration needs to be changed. For the NetApp, you would likely run the "network interface modify" command (manual page here) to change the subnet mask - either via command line or GUI. For the client, you would change your DHCP server or local interface config.

 

Hope this helped!

Hi there,

 

No, there aren't any restrictions like that. My guess would be that the subnet mask is wrong on either the cluster/node management LIF of your NetApp system, or less likely, on your client.

 

Can you ping it?

unable to ping

Can you post the output of "network interface show" from your NetApp system, as well as "ipconfig /all" of your system on wireless?
