Trunking between Gbe2c and HI 5500

[savisjsc]

Hi all.

I'm having problem with my HP C7000 blade and 5500 HI Switch Core.

My scenario:

16 x Blade Server -> connect to 02 x Gbe2c Switch (Using Windows 2012 NIC Teaming) -> Connect to  2 x HI 5500 (LACP trunking and IRF already on HI 5500).

I've tried ping to Blade Server but TTL = 127 but Gateway at 5500 = 255. Anyone can help me on it?

Also i'm having problem with STP between them. When i've enable 2 Gbe2c then my Network DOWN. STP s*cking me on this. Could anyone give me advance on it :(

Thanks,
