Disabling MAC Learning in a VLAN
By default, MAC learning is enabled on a VLAN. This topic describes how to disable MAC learning in a VLAN, as well as how to reenable and verify that MAC learning has been enabled or disabled.
Disabling dynamic MAC learning in a VLAN on a QFX Series product prevents a node from learning source and destination MAC addresses.
- To disable MAC learning in a VLAN:
[edit vlans vlan-name]
user@switch# set no-mac-learning - To reenable MAC learning in a VLAN, use either of the
following two commands:
[edit vlans vlan-name]
user@switch# delete no-mac-learning
user@switch# deactivate no-mac-learning - To verify the status of MAC learning on the QFX series:
user@switch> show ethernet-switching table
