| Note |

Every switch chip has a finite number of MAC addresses it can store on the chip, see the Introduction table for a specific host table size. Once a host table is completely full, different techniques can be utilized to cope with the situation, for example, the switch can remove older entries to free space for more recent MAC addresses (used on QCA-8337 and Atheros-8327 switch chips), another option is to simply ignore the new MAC addresses and only remove entries after a timeout has passed (used on Atheros8316, Atheros8227, Atheros-7240, ICPlus175D and Realtek-RTL8367 switch chips), the last option is a combination of the previous two - only allow a certain amount of entries to be renewed and keep the other host portion intact till the timeout (used on MediaTek-MT7621 switch chip). These techniques cannot be changed with configuration. |
| Note |
|---|
For Atheros8316, Atheros8227 and Atheros-7240 switch chips, the switch-cpu port will always participate in the host learning process when at least one hardware offloaded bridge port is active. This will allow to learn MAC addresses also from non-HW offloaded interfaces. To avoid MAC address conflict, make sure that there are no duplicate MAC addresses on the same switching group regardless if hosts are located on different logical networks. |
Rule Table
Rule table is a very powerful tool allowing wire-speed packet filtering, forwarding and VLAN tagging based on L2, L3 and L4 protocol header field condition. The menu contains an ordered list of rules just like in /ip firewall filter, so ACL rules are checked for each packet until a match has been found. If there are multiple rules that can match, then only the first rule will be triggered. A rule without any action parameters is a rule to accept the packet.
