Recovering from Learning Limit and Station Move Violations
After a learning-limit or station-move violation shuts down an interface, you must manually reset it:
Per-VLAN MAC Learning Limit
Per-VLAN MAC Learning Limit is available only on platform: e
An individual MAC learning limit can be configured for each VLAN using Per-VLAN MAC Learning
Limit.
One application of Per-VLAN MAC Learning Limit is on access ports. In Figure 25-1, an Internet
Exchange Point (IXP) connects multiple Internet Service Provider (ISP). An IXP can provide several types
of services to its customers including public an private peering. Public peering means that all customers are
connected to one VLAN, and if one ISP wants to peer with another ISP, it establishes a BGP peering
session over this VLAN. Private Peering means that the IXP sets up a separate VLAN between two
customers that want to peer privately; only the ports of these two ISPs would belong to this VLAN, and
they would peer via BGP. In Figure 25-1, Per-VLAN MAC Learning Limit is used on the access ports for
the ISPs that have subscribed to private and public peering since these access ports are members of
multiple VLANs.
