hello, we encountered a problem that Broadcom BCM57404 NetXtreme-E 10Gb/25Gb Ethernet Controller dual port network cards do not send their mac address on the switch port cisco nexus 3064, but there is a link UP the DAC cable.

Added if_bnxt_load="YES" to /boot/loader.conf

there are no problems in dmesg either.

in rc.conf, a static IP address is set on bnxt0 or bnxt1 and, accordingly, an IP address from this subnet is also raised on the switch port.

I tried to insert sfp + 10gb instead of a dac cable, there is a link up, but the network card does not send mac address to the port.

I tried it on different switches.

I tried to install Intel XXV710-DA2 10/25GbE SFP28 2-Port PCIe Ethernet Adapter instead of broadcom network card and everything works fine with intel.


broadcom network card has driver and firmware

sysctl dev.bnxt.0.ver.hwrm_fw
dev.bnxt.0.ver.hwrm_fw: 212.0.162

sysctl dev.bnxt.0.ver.hwrm_if
dev.bnxt.0.ver.hwrm_if: 1.9.1

Tell me what is the reason that network broadcom 10/25gb may not send mac address to the switch port, at the same time, the network card settings in rc.conf and switch cisco nexus 3064  switch are correct.
