Ingress-filtering ( yes | no Default: no)Įnables or disables ingress filtering, which checks if an entry exists for the ingress port and the VLAN ID in the bridge VLAN table.
Only has effect when ingress-filtering is enabled. Specifies allowed ingress frame types on a bridge port. to frames sent from bridge IP and destined to a bridge port.įrame-types ( admit-all | admit-only-untagged-and-priority-tagged | admit-only-vlan-tagged Default: admit-all) Port VLAN ID (pvid) specifies which VLAN the untagged ingress traffic is assigned to. Globally enables or disables VLAN functionality for bridge. Make sure that all bridge ports have the "H" flag, which indicates that the device is using the switch chip to forward packets.

On CRS3xx series devices VLAN switching must be configured under the bridge section as well, this will not limit the device's performance, CRS3xx is designed to use the built-in switch chip to work with bridge VLAN filtering, you are able to achieve full non-blocking wire-speed switching performance while using bridges and bridge VLAN filtering. Note: Since RouterOS v6.41 all VLAN switching related parameters are moved to the bridge section.
Besides joining the ports for Layer2 forwarding, bridge itself is also an interface therefore it has Port VLAN ID (pvid). Turning on vlan-filtering enables all bridge VLAN related functionality and independent-VLAN-learning (IVL) mode. If vlan-filtering=no, bridge ignores VLAN tags, works in a shared-VLAN-learning (SVL) mode and cannot modify VLAN tags of packets. The main VLAN setting is vlan-filtering which globally controls vlan-awareness and VLAN tag processing in the bridge. Bridge VLAN Filtering configuration is highly recommended to comply with STP (802.1D), RSTP (802.1w) standards and is mandatory to enable MSTP (802.1s) support in RouterOS. This set of features makes bridge operation more like a traditional Ethernet switch and allows to overcome Spanning Tree compatibilty issues compared to configuration when tunnel-like VLAN interfaces are bridged. Since RouterOS v6.41 bridges provides VLAN aware Layer2 forwarding and VLAN tag modifications within the bridge. Note: On CRS3xx series switches bridge STP/RSTP/MSTP, IGMP Snooping and VLAN filtering settings don't affect hardware offloading, since RouterOS v6.42 Bonding interfaces are also hardware offloaded. In order to setup port switching on CRS3xx series switches, check the Bridge Hardware Offloading page. This table clarifies main differences between Cloud Router Switch models. ACL actions include filtering, forwarding and modifying of the protocol header fields.Classification based on ports, L2, 元, L4 protocol header fields.Applicable for Private VLAN implementation.Hardware automatic failover and load balancing.Up to 8 member ports per bonding interface.
