4. Media access control (MAC) addresses (CNAs only)
The CNA card MAC address can be found in HCM by selecting the CNA in the device tree and
clicking the Properties tab in the right pane. This displays the CNA Properties panel. Look for
the MAC Address field.
The CNA MAC address can be found in HCM by selecting the CNA in the device tree and clicking
the Properties tab in the right pane to display the CNA Properties panel. Look for the MAC
Address field.
Each port has a “burned-in” local port MAC address. This is the source MAC for LLDP
communications between the CNA and FCoE switch. To find this MAC address, select a CEE
port in the HCM device tree, then click the Properties tab in the right pane to display the port
Properties panel. Look for the Local port MAC field.
The Ethernet MAC address is used for normal Ethernet operations. To find this MAC address
using HCM, select an Ethernet port in the HCM device tree, then click the Properties tab in the
right pane to display the port Properties panel. Look for the Current MAC address and Factory
MAC address fields.
Each enode logging in to the fabric through a local CNA port is assigned a MAC address during
FCoE Initialization Protocol (FIP) operations. This MAC is assigned for the current FCoE
communication only. To find this MAC address, perform one of the following tasks:
•
Select an FCoE port in the HCM device tree, then click the Properties tab in the right
pane to display the port Properties panel. Look for the FCoE MAC field.
•
Enter the port --query
port_id
BCU command. Look for the FCoE MAC.
NOTE
MAC addresses assigned during FCoE initialization operations cannot be changed using device
management applications.
The FCoE Forwarder (FCF) MAC address is the address of the attached FCoE switch. Select an
FCoE port in the HCM device tree, then click the Properties tab in the right pane to display the
port Properties panel. Look for the FCF MAC field.
You can also determine port MAC addresses using the following BCU commands:
Command
Function
port --query <port_id>
Displays port information, including the PWWN
for the FCoE port. The
port_id
parameter is the
port number.
port --list
Lists all the physical ports on the adapter along
with their basic attributes, such as the PWWN.
Command
Function
port ---query
port_id
Displays port information, including the MAC
addresses. The <port_id> parameter is the
port number.
port ---list
Lists all the physical ports on the adapter along
with their Ethernet and FCoE MAC addresses.
