Ping on Ap -Manager interface

[m.arienti]

Hello,

during the configuration of a Wlc 4402 with firmware 7.0.98.0 i see that is possibly to ping the Ap-manager interface of my WLC.

With the previous firmware I saw, and I read that is correct on Cisco documentation that is not possible to ping the Ap-Manager interface, is a problem about configuration or is a new features of the new firmware?

Thanks

Marco

Pinging the ap-manager might or might not work depending on complex conditions. It has always been in all firmwares.

Anyway there is little point in doing so since you cannot rely on the result :-)

The AP-Manager interface will not respond to ICMP echo requests in all releases prior to 6.0.202. I have WiSM's and WLC's on 4.0, 5.2, and up to 6.0.199.4 that will not answer pings. My controllers that are on 6.0.202 and up will answer pings. I do not know why Cisco decided to change this at that realease.

Well I never knew that you could ping the ap manager. Like you said it might of been allowed in the older code but not on the newer code. It's more important to know you can ping the management ip though and not really the ap manager.

Just the opposite: not allowed in older code but allowed in newer code. You are correct, the manageent interface is what you would normally ping anyway.

AP-Manager is pingable in 7.0 because it shares same mac address as management interface.

"

Note

With the 7.0 release onwards, the MAC address of the management interface and the AP-manager interface is the same as the base LAG MAC address."

This is why it may respond. management interface is still the only consistently pingable in-band interface though.
