Concept Guide
• interface: deletes all entries for the specied interface.
Displaying the MAC Address Table
To display the MAC address table, use the following command.
• Display the contents of the MAC address table.
EXEC Privilege mode
NOTE: This command is available only in PMUX mode.
show mac-address-table [address | aging-time [vlan vlan-id]| count | dynamic | interface |
static | vlan]
– address: displays the specied entry.
– aging-time: displays the congured aging-time.
– count: displays the number of dynamic and static entries for all VLANs, and the total number of entries.
– dynamic: displays only dynamic entries.
– interface: displays only entries for the specied interface.
– static: displays only static entries.
– vlan: displays only entries for the specied VLAN.
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.
NOTE
: You can use the mac-address-table disable-learning command only in Full–Switch mode.
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.
