Disabling MAC Learning for Bridge Domains on ACX Series
You can disable MAC learning in a bridge domain. Disabling dynamic MAC learning
prevents the bridge domain from learning source MAC addresses.
To disable MAC learning in a bridge domain, include the no-mac-learning statement at
the [edit bridge-domains bridge-domain-name bridge-options] hierarchy level:
[edit]
bridge-domains {
bridge-domain-name {
bridge-options {
no-mac-learning;
}
}
}
NOTE: When you disable MAC learning, source MAC addresses are not
dynamically learned, and any packets sent to these source addresses are
flooded into the bridge domain.
