Setup Guide
Disabling MAC Address Learning on the System
You can congure the system to not learn MAC addresses from LACP and LLDP BPDUs.
To disable source MAC address learning from LACP and LLDP BPDUs, follow this procedure:
• Disable source MAC address learning from LACP BPDUs.
CONFIGURATION mode
mac-address-table disable-learning lacp
• Disable source MAC address learning from LLDP BPDUs.
CONFIGURATION mode
mac-address-table disable-learning lldp
• Disable source MAC address learning from LACP and LLDP BPDUs.
CONFIGURATION mode
mac-address-table disable-learning
If you don’t use any option, the mac-address-table disable-learning command disables source MAC address learning from
both LACP and LLDP BPDUs.
Enabling port security
You can enable or disable port security feature globally on the Dell EMC Networking OS.
You can congure all the MAC address learning limit congurations, only if the port security is enabled on the Dell EMC Networking OS. If
the port security feature is disabled, all the interface level congurations are reset and all dynamically learnt MAC addresses on the
interfaces congured with MAC address learning limit are cleared.
To enable the port security feature globally in the system, use the following command.
• Enable the port security feature.
CONFIGURATION mode
mac port-security
NIC Teaming
NIC teaming is a feature that allows multiple network interface cards in a server to be represented by one MAC address and one IP address
in order to provide transparent redundancy, balancing, and to fully utilize network adapter resources.
The following illustration shows a topology where two NICs have been teamed together. In this case, if the primary NIC fails, trac
switches to the secondary NIC because they are represented by the same set of addresses.
