wireless lan Controller 4402 / ping dynamic interface failed

hi,

i've a problem with a Wireless Lan Controller 4402.

When i configure the dynamic interface on the my network , with wired lan

i don't reach (i use the ping command) the ip address of the WLC.

In my case (wired):

On my pc i've a ip 10.1.78.1 255.255.0.0 and dgw 10.1.1.1 (vlan721)

The lan WLC have a ip of management 10.12.2.4 /24 (vlan799) [dgw 10.12.2.1]

dynamic vlan 792 ip add 10.12.78.100 / 22 (vlan792) [dgw 10.12.68.1]

i ping these interfaces (10.12.2.4 and 10.12.78.100) and the ping is ok.

When i create a dynamic interface vlan 721 starting the problem:

dynamic vlan 791 ip address 10.1.1.240 / 16 (vlan721)

After this ......the ping on 10.12.2.4 and 10.12.78.100 don't respond very well

and i lose the 80-90% of the ping packages.

through the wi-fi instead I do not have problems.

the problem exist only via wired (cable).

Can you help me?

Thanks

Re: wireless lan Controller 4402 / ping dynamic interface failed

Hello,

Pinging the dynamic interface is officially not supported. The reason why is because the controller places a very low priority on ICMP traffic. Typically, you will not have an issue with doing so on your wireless network because this interface is basically a gateway for the client. However, from the wired network - the only interface designed to respond to pings 100% of the time is the management interface. Hope this helps!
