Viewing MAC Addresses in the System Configuration
This section describes how to view MAC addresses in the system configuration.
Guidelines
If you manually assign a MAC address to an interface, but also have auto-generation enabled, the
auto-generated address continues to show in the configuration even though the manual MAC address is
the one that is in use. If you later remove the manual MAC address, the auto-generated one shown will
be used.
Detailed Steps
Step 1 If you are not already in the System configuration mode, in the Device List pane, double-click System
under the active device IP address.
Step 2 Choose the Configuration > Context Management > Security Contexts pane, and view the Primary
MAC and Secondary MAC columns.
Viewing MAC Addresses Within a Context
This section describes how to view MAC addresses within a context.
Detailed Steps
Step 1 If you are not already in the System configuration mode, in the Device List pane, double-click System
under the active device IP address.
Step 2 Choose the Configuration > Interfaces pane, and view the MAC Address address column.
This table shows the MAC address in use; if you manually assign a MAC address and also have
auto-generation enabled, then you can only view the unused auto-generated address from within the
system configuration.
