Thanks for you reply
Question arosefor such a reason
Supermicroservers havea dedicated port for BMCas well asthe ability to accessthrough other LAN port after setting ipmi-over-lan
With the Supermicro wordsusing IPMI in Supermicro server from not dedicated BMC port (from other motherboard LAN port) have the problem.
BMCis connected toother gigabit LAN ports (on the one motherboard) from some switch. This switch have bandwidth around 400 Kb.
Hence non dedicated LAN for BMC connect has a lowbandwidth.This can be seenwhen connecting from remoteconsolewhen browsable host use graphic interface.
Is interestingif there isthe same probleminintelservers
P.S.sorry, I wrong, motherboard S2600 series
