A method, apparatus and computer program product for performing Routed Split Multi-Link Trunking Resiliency for Wireless Local Area Network split-plane environments is presented. A first network switch learns first data associated with a second network switch and the first network switch terminates an Access Tunnel (AT). The said second network switch learns second data associated with said first network switch. The first and second data are synchronized between the first network switch and the second network switch. The first network switch and the second network load sharing tunnel data packets. The second network switch forwards tunnel control packets received by the second network switch to the first network. A failure relating to said first network switch is detected and a new AT is established with the second network switch.

Multiple non-conflicting actions associated with filter rules may be located and applied to a packet using a single ACL lookup by causing action records to be created from ACEs in the ACL, and then causing the ACL lookup to return the action record rather than any one particular ACE. Radix tables may be created to enable a search engine to quickly locate the appropriate action record based on a particular set of attributes associated with the incoming packet. The action record can contain multiple actions taken from multiple ACEs that apply to the particular packet. By grouping all the actions into an action record, and then searching for an action record that applies to the packet, it is possible to apply all non-conflicting actions to the packet regardless of the number of ACEs that are used to specify those actions. Since all the actions are located together, the actions of all ACEs may be applied to a packet using a single ACL lookup.

A method, apparatus and computer program product for providing Routed Split Multi Link Trunking (RSMLT) for Wireless Local Area Network (WLAN) tunnels is presented. A first and second network switch learn data associated with each other, wherein the first network switch and the second network switch operate concurrently. The first network switch terminates a WLAN Tunnel. The data is synchronized between the first network switch and the second network switch, wherein the data includes MAC Addresses, Internet Protocol (IP) interface addresses, Virtual Local Area Network (VLAN) associations, WLAN tunnel assignments and Network switch Internet Protocol (IP) addresses. Load sharing of tunnel data packets is performed by the first and the second network switch. Tunnel control packets received by the second network switch are forwarded to the first network switch over an Inter Switch Trunk (IST).

A method, apparatus and computer program product for providing failover for a point to point tunnel for wireless local area network split-plane environments is presented. A second network switch learns first data associated with a third network switch and the second network switch terminates a tunnel. The third network switch learns second data associated with the second network switch. The first and second data are synchronized between the second network switch and the third network switch. The second network switch and the third network switch load sharing tunnel data packets. The third network switch forwards tunnel control packets received by the third network switch to the second network switch. A failure relating to the second network switch is detected and a new tunnel is established with the third network switch.

A method, apparatus and computer program product for forming a tiered Wireless Local Area Network (WLAN) server topology is presented. A Wireless Local Area Network (WLAN) having a plurality of Mobile Virtual Local Area Network (MVLAN) servers is broken into a plurality of zones, each zone including at least one MVLAN server. An Identifier (ID) is assigned to each zone. A MVLAN server in each zone is designated as a MVLAN gateway server, wherein MVLAN servers within a zone communicate with each other within the zone, wherein the MVLAN servers within a zone communicate directly with the MVLAN gateway sever within the zone, wherein MVLAN gateway servers communicate directly with each other, and wherein a MVLAN server within a first zone communicates with a MVLAN server in a second zone by way of the MVLAN gateway sever of the first zone and the MVLAN gateway server of the second zone.
