Configuring the Size of the MAC Address Table for a Bridge Domain
You can modify the size of the MAC address table for each bridge domain. The default table size is 5120 addresses. The minimum you can configure is 16 addresses, and the maximum is 1,048,575 addresses.
If the MAC table limit is reached, new addresses can no longer be added to the table. Unused MAC addresses are removed from the MAC address table automatically. This frees space in the table, allowing new entries to be added.
To modify the size of the MAC table, include the mac-table-size limit statement at the [edit bridge-domains bridge-domain-name bridge-options] hierarchy level:
[edit] bridge-domains { bridge-domain-name { domain-type bridge; bridge-options { mac-table-size limit { packet-action drop; } } } }
