Conguring a Static MAC Address
A static entry is one that is not subject to aging. Enter static entries manually.
To create a static MAC address entry, use the following command.
• Create a static MAC address entry in the MAC address table.
CONFIGURATION mode
mac-address-table static
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
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.
MAC Learning Limit
MAC address learning limit is a method of port security on Layer 2 port-channel and physical interfaces, and VLANs. It allows you to set an
upper limit on the number of MAC addresses that learned on an interface/VLAN. After the limit is reached, the system drops all trac from
a device with an unlearned MAC address.
This section describes the following:
• Setting the MAC Learning Limit
• mac learning-limit Dynamic
• mac learning-limit mac-address-sticky
• mac learning-limit station-move
• Learning Limit Violation Actions
• Setting Station Move Violation Actions
• Recovering from Learning Limit and Station Move Violations
Dell EMC Networking OS Behavior: When conguring the MAC learning limit on a port or VLAN, the conguration is accepted (becomes
part of running-config and show mac learning-limit interface) before the system veries that sucient CAM space
exists. If the CAM check fails, a message is displayed:
%E90MH:5 %ACL_AGENT-2-ACL_AGENT_LIST_ERROR: Unable to apply access-list Mac-Limit on
