Title:
Failed to achieve more than 80% of the bandwidth on a 100Gbps
connection during the network test
Status in linux package in Ubuntu:
Confirmed
Bug description:
Server Details:
SUT - Cisco UCS X210c M7
Ubuntu OS - 22.04/24.04
VIC/Ethernet Adapter - Cisco UCS VIC 15231 / UCSX-ML-V5D200G
he SUT is configured to run the network test using the canonical-
certification-server package, with both the SUT and iPerf test servers
set up as per the Test Suite Guide. Both servers are in a 100Gb switch
environment. The issue occurs with achieving 80-90% bandwidth during
the network stress test, and this is observed on both blade and rack
servers.
However, when testing with 10G and 25G network speeds, 80-90% bandwidth is
successfully achieved. Below is a list of network cards on which the network
tests passed.
Cisco UCS VIC 15427
Cisco UCS VIC 15420
