Re: can't ping IAP

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

Re: can't ping IAP


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.

thank you for your help!!!




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 :

VC Mask :
VC Gateway :

Master IP Address *:
IP Address :
Netmask :
Gateway :
NameServer :


So you are able to ping but not, 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 to

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