Ethernet Information

Below is documented how a driver should set this information, and where it shows.

This typically is loaded when the driver’s get_my_client_data() function is called. I.e. This is when the user click the ‘Read Arp/LLDP’ button.

The EthernetAddress() class is used to store MAC address information. See the definition in openl2m/switches/connect/classes.py

Ethernet information is stored for each Interface(), in the interface.eth* dictionary, with key “ethernet address” as string.

I.e. the interface.eth dictionary contains the ethernet address heard on a particular interface.

Storing Ethernet Addresses

There are a number of functions to help with storing ethernet address:

connector.add_learned_ethernet_address()

This can be used to add an ethernet as string to an interface name, with IPv4 (aka Arp) and Vlan data if known.

interface.add_learned_ethernet_address()

Same as above, but can be used if you already have the Interface() object.

Where does it shows

This shows under the ‘Arp/LLDP’ tab, and is rendered in the file templates/_tab_if_arp_lldp.html

See the code segment similar to this, inside the ‘for each interface’ loop:

# around line 29:
{% for key,iface in connection.interfaces.items %}

    # around line 74
    {% if connection.eth_addr_count > 0 %}
        <td>{# known ethernet addresses #}
            {% for macaddr, eth in iface.eth.items %}
            <div>
                ...
