Wifi Access Point DLink as a client to cisco mesh net (look on the picture #1). AXIS video encoder connected to Dlink. If i ping AXIS from wired lan (from catalyst 3750), it cannot be pinged. If I connect DLink client ap to AXIS through switch and also pc there, ASIS can be pinged well.
If I add static arp to that 3750 (it acts as a core router).
If I connect this dlink to another (picture 2), all works ok.
