  • Hello! I've reviewed the HPE FlexFabric 5940 & 5930 Switch Series Layer 2 LAN Switching Command Reference. This document details various commands for configuring and managing your switches, covering areas like MAC address tables, Ethernet interfaces, VLANs, and link aggregation. I'm ready to help answer any questions you have about using these commands to configure your device.
  • What is the command to display the MAC address table?
    How do I configure link aggregation?
    What command is used to display interface information?
    How can I enable or disable MAC address learning?

MAC address table commands
This document covers the configuration of unicast MAC address entries, including static, dynamic,
blackhole, and multiport unicast MAC address entries. For more information about configuring static
multicast MAC address entries, see IGMP snooping and IPv6 multicast routing and forwarding in IP
Multicast Configuration Guide. For more information about MAC address table configuration in
VPLS, see MPLS Configuration Guide.
display mac-address
Use display mac-address to display MAC address entries.

Parameters
mac-address: Specifies a MAC address in the format of H-H-H. When entering a MAC address,
you can omit the leading zeros in each H section. For example, enter f-e2-1 for 000f-00e2-0001.
vlan vlan-id: Specifies a VLAN by its ID in the range of 1 to 4094.
dynamic: Displays dynamic MAC address entries.
static: Displays static MAC address entries.
interface interface-type interface-number: Specifies an interface by its type and
number.
blackhole: Displays blackhole MAC address entries.
multiport: Displays multiport unicast MAC address entries.
count: Displays only the number of MAC address entries that match all entry attributes you specify
in the command. Detailed information about MAC address entries is not displayed. For example, you
can use the display mac-address vlan 20 dynamic count command to display the number
of dynamic entries for VLAN 20. If you do not specify an entry attribute, the command displays the
number of entries in the MAC address table. If you do not specify this keyword, the command
displays detailed information about the specified MAC address entries.
nickname nickname: Specifies an egress RB by its nickname. The value range for the
nickname argument is 1 to fffe in hexadecimal format.
Usage guidelines
A MAC address entry includes a destination MAC address, an outgoing interface, and a VLAN ID.
If you do not specify any parameters, the command displays all MAC address entries.
This command displays dynamic MAC address entries for an aggregate interface only when the
aggregate interface has a minimum of one Selected member port.
2
Multiport unicast MAC address entries have no impact on the MAC address learning. When
receiving a frame whose source MAC address matches a multiport unicast entry, the device can still
learn the MAC address of the frame and generate a dynamic entry. However, the generated dynamic
entry has lower priority. The device prefers to use the multiport unicast entry to forward frames
destined for the MAC address in the entry.
Examples
# Display MAC address entries for VLAN 100.

Parameters
slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a
member device, the command displays MAC address move records for all IRF member devices.
Usage guidelines
When a MAC address frequently moves between the specified two interfaces, Layer 2 loops might
occur in the network. To discover and locate loops, you can view the MAC address move records.
In the MAC address move records, records with the same MAC address, VLAN, source port, and
current port are considered to be one record.
An IRF member device can generate a maximum of 200 MAC address move records.
Examples
# Display the MAC address move records for a slot.

Parameters
dynamic: Specifies dynamic MAC address entries.
static: Specifies static MAC address entries.
multiport: Specifies multiport unicast MAC address entries. A frame whose destination MAC
address matches a multiport unicast MAC address entry is sent out of multiple ports.
mac-address: Specifies a MAC address in the format of H-H-H, excluding multicast, all-zero, and
all-F MAC addresses. When entering a MAC address, you can omit the leading zeros in each H
section. For example, enter f-e2-1 for 000f-00e2-0001.
vlan vlan-id: Specifies an existing VLAN to which the specified interface belongs. The value
range for the vlan-id argument is 1 to 4094.
Usage guidelines
Typically, the device automatically builds the MAC address table by learning the source MAC
addresses of incoming frames on each interface. However, you can manually configure static MAC
address entries. For a MAC address, a manually configured static entry takes precedence over a
dynamically learned entry. To improve the security for the user device connected to an interface,
manually configure a static entry to bind the user device to the interface. Then, the frames destined
for the user device (for example, Host A) are always sent out of the interface. Other hosts using the
forged MAC address of Host A cannot obtain the frames destined for Host A.
The MAC address entry configuration cannot survive a reboot unless you save it. The dynamic MAC
address entries, however, are lost upon reboot whether or not you save the configuration.

interface-number2. The interfaces can only be Layer 2 Ethernet interfaces or Layer 2
aggregate interfaces. The value for the interface-number2 argument cannot be lower than the
value for the interface-number1 argument.
nickname nickname: Specifies an RB (through which the packets leave the TRILL network) by its
nickname. The nickname is a hexadecimal number in the range of 1 to fffe.
Usage guidelines
You can use this command to configure the following types of MAC address entries:
• Dynamic entries.
Dynamic entries include manually configured dynamic entries and automatically learned
dynamic entries.
• Static entries.
For a MAC address, a manually configured static entry takes precedence over a dynamic entry.
To improve the security for the user device connected to an interface, manually configure a
static entry to bind the user device to the interface. Then, the frames destined for the user
device (for example, Host A) are always sent out of the interface. Other hosts using the forged
MAC address of Host A cannot obtain the frames destined for Host A.
• Blackhole entries.
To drop frames with the specified source MAC addresses or destination MAC addresses, you
can configure blackhole entries.
• Multiport unicast entries.
To send frames with a specific destination MAC address out of multiple ports, configure a
multiport unicast entry. When you execute this command for the first time, the command adds
an entry. When you execute the command again with the same MAC address and VLAN but
with different interfaces, this command adds the specified interfaces for this entry.
A static or blackhole entry can overwrite a dynamic entry, but not vice versa.
If you execute the undo mac-address command without specifying any parameters, this
command deletes all unicast MAC address entries and static multicast MAC address entries.
You can delete all the MAC address entries (including unicast and static multicast MAC address
entries) from the specified VLAN. You can also delete only one type (dynamic, static, blackhole, or
multiport unicast) of MAC address entries. You can single out an interface and delete the unicast
MAC address entries on it, but not the static multicast MAC address entries. You can single out an
RB through which the packets leave the TRILL network and delete the corresponding unicast MAC
address entries.
The MAC address entry configuration cannot survive a reboot unless you save it. The dynamic MAC
address entries, however, are lost upon reboot whether or not you save the configuration.
