Re: can't ping IAP

Are you pinging from the second subnet?
Is it a wired or wireless client?

Re: can't ping IAP

hi,

it's a wire client.

all IAPs and the virtual controller are in the same subnet.

Re: can't ping IAP

Can you share a show tech so we better know IP addressing gateway scheme used. Also provide IP of the wired client.

Re: can't ping IAP

1. Show tech from master IAP would be best attached as its huge. i think you got the show summary. show tech would have given more details e.g. software version, or any funny logs.

 

2. From the shared information:

VC IP Address :10.225.61.253

VC VLAN :0
VC Mask :0.0.0.0
VC Gateway :0.0.0.0
VC DNS :0.0.0.0

Master IP Address *:10.225.61.101
IP Address :10.225.61.101
Netmask :255.255.255.0
Gateway :10.225.61.254
NameServer :8.8.8.8

 

So you are able to ping 10.225.61.253 but not 10.225.61.101, from a PC in another subnet.

 

Assuming this is the native / untagged VLAN (share VLAN number) on the ports leading to IAPs. Can you:

 

a) make sure mask & gateway info is consistent on all devices.

b) ping from gateway 10.225.61.254 to 10.225.62.101

c) does SSH work to .253 and .101, from the network?
