HP Dl180 G6 Lights Out

[chupin]

I have some problems with lights out settings on HP DL180 G6 platform. 

So, on new server I set up IPMI LAN settings, IPMI was set in Shared mode, VLAN support was disabled. Switch had port in access-mode. I could ping server and had access to web-interface.

Then, I set VLAN enabled via Web-interface, and set switchport to trunk mode. After this, I lost access to web-interface. When I tried to ping server, nine out of ten packets lost. Switch had not errors on interface.

Switch config:

interface FastEthernet0/11
description 900: iLo hp rev. 20131111 m.chupin
switchport trunk allowed vlan 517,518
switchport mode trunk
switchport nonegotiate
snmp ifindex persist
storm-control broadcast level 10.00
storm-control multicast level 10.00
storm-control action trap
spanning-tree portfast

cmd output:

Statistic Ping for 172.21.18.20:
Packets: send = 1079, received = 81, lost = 998
(92% loss)

How can I reset ipmi settings? 

How must I configure switch?
