25.9.3 RMCP / ASF Messaging
The BMC suppor t s RMCP ping discovery in which t he BMC responds wi t h a pong message t o an RMCP / ASF ping
reques t. This is implemen t ed per t he I n t elligen t Pla tf orm Managemen t I n t er f ace Speci f ica t ion Second Genera t ion
v2 . 0 .
25.9.4 BMC Embedded LAN Channels
BMC hardware includes t wo dedica t ed 10 / 100 ne t work in t er f aces ,
I nterface 1: This in t er f ace is available f rom ei t her o f available N I C por t s in sys t em which can be shared wi t h t he hos t.
Only one N I C may be enabled f or managemen t t ra ff ic a t any t ime . To change t he N I C enabled f or managemen t
t ra ff ic , please use t he “ Wri t e LAN Channel Por t ” OEM I PM I command . The de f aul t ac t ive in t er f ace is por t 1 (N I C1) .
I nterface 2: This in t er f ace is available f rom RMM3 which is dedica t ed managemen t N I C and no t shared wi t h hos t.
For t hese channels , suppor t can be enabled f or I PM I -over-LAN and DHCP .
For securi t y reasons , embedded LAN channels have t he f ollowing de f aul t se tt ings :
x
I P Address : S t a t ic
x
All users disabled
IPM I -enabled ne t work in t er f aces may no t be placed on t he same subne t. This includes t he I n t el RMM3’s onboard
ne t work in t er f ace , and ei t her o f t he BMC’s embedded ne t work in t er f aces .
Hos t -BMC communica t ion over t he same physical LAN connec t ion – also known as “ loopback ” – is no t suppor t ed .
This includes “ ping ” opera t ions .
25.9.5 BMC IP Address Configuration
Enabling t he BMC’s ne t work in t er f aces requires using t he Se t LAN Con f igura t ion Parame t er command t o con f igure
LAN con f igura t ion parame t er 4 , I P Address Source . BMC suppor t s t his parame t er as f ollows :
x
1h , s t a t ic address (manually con f igured) : Suppor t ed on all managemen t N I Cs . This is t he BMC’s de f aul t value .
x
2h , address ob t ained by BMC running DHCP : Suppor t ed only on embedded managemen t N I Cs .
I P Address Source value 4h , address ob t ained by BMC running o t her address assignmen t pro t ocol , is no t suppor t ed
on any managemen t N I C .
A tt emp t ing t o se t an unsuppor t ed I P address source value has no e ff ec t, and t he BMC re t urns error code 0xCC ,
I nvalid da t a f ield in reques t. No t e t ha t values 0h and 3h are no longer suppor t ed , and will re t urn a 0xCC error
comple t ion code .
25.9.5.1 Static IP Address (IP Address Source Values 0h, 1h, and 3h)
The BMC suppor t s s t a t ic I P address assignmen t on all o f i t s managemen t N I Cs . The I P address source parame t er
mus t be se t t o “ s t a t ic ” be f ore t he I P address , t he subne t mask or ga t eway address can be manually se t.
The BMC t akes no special ac t ion when one o f t he f ollowing I P address sources is speci f ied as t he I P address source
f or any managemen t N I C :
 1h – S t a t ic address (manually con f igured)
There f ore , any o f t hese se tt ings is equivalen t t o a s t a t ic I P address con f igura t ion . The Se t LAN Con f igura t ion
Parame t er command mus t be used t o con f igure LAN con f igura t ion parame t er 3 , I P Address , wi t h an appropria t e
value .
The B I OS does no t moni t or t he value o f t his parame t er , and i t does no t execu t e DHCP f or t he BMC under any
circums t ances , regardless o f t he BMC con f igura t ion .
