Identifying MZ522 Ports in Linux

To identify MZ522 ports in RHEL 7.2, perform the following steps:

Run the lspci | grep BCM57810 command on the Linux command line interface (CLI) to view MZ522 PCIe functions.

Figure 4-176 shows the MZ522 PCIe devices when NPAR is disabled.

The preceding information shows four MZ522 NIC devices.

Run the ifconfig -a command on the Linux CLI to view the four NIC ports. In RHEL 7.2, NIC ports are named in the format of enp[bus_num]s[dev_num]f[fun_num]. In the name, bus_num, dev_num, and fun_num indicate the PCIe bus number, device number, and function number respectively. See Figure 4-177.

In SLES and RHEL earlier than 7.0, eth[num] is used to name a network port by default and the value of num increases when NICs are replaced or the number of network ports increases.

The MZ522 allocates MAC addresses to physical ports. Table 4-4 lists the mapping between physical ports and MAC addresses.

After NPAR is enabled, each physical port supports four PFs. Figure 4-178 lists the PCIe devices and each PCIe device is a PF.

After NPAR is enabled, the FCoE/iSCSI functions of each physical port can be allocated to any PF. Table 4-5 lists the mapping between physical ports and MAC addresses.
