摘要： A first aggregation layer device at a first site learns Media Access Control (MAC) address information received from a second aggregation layer device at a second site. The MAC address information includes: a VLAN identifier (ID), an aggregated MAC address, and an aggregated MAC address mask configured at the second site. When receiving a message addressed to the VLAN ID and a destination MAC address, the first aggregation layer device searches for the MAC address information based on the VLAN ID and destination MAC address and forwards the message to the second aggregation layer device according to the MAC address information. The destination MAC address belongs to the same MAC address segment as the aggregated MAC address and searching for the MAC address information includes mask matching based on the aggregated MAC address mask.

摘要： Aspects of the present invention include an N-Node virtual link trunking (VLT) system comprising a set of N nodes collectively provide a logical fabric-level view that is consistent across the set of N nodes. Embodiments of the N-Node VLT system comprise a control plane mechanism to provide Layer 2 multipathing between access network devices (switches or servers) and the core network. The N-Node VLT system provides a loop-free topology with active-active load-sharing of uplinks from access to the core. Accordingly, the N-Node VLT system eliminates the disadvantage of Spanning Tree Protocol (STP) (active-standby links) by allowing link aggregation group (LAG) terminations on multiple separate distribution or core switches and also supporting a loop-free topology. Additional benefits of an N-Node VLT system include, but are not limited to, higher resiliency, improved link utilization, and improved manageability of the network.

摘要： Methods and systems are described for assigning the proper internet protocol (IP) address to a client device following authentication of the client device on a network. In particular, at commencement of an authentication procedure of the client device, a role is associated with the client device that denies all DHCP renews/requests. By assigning a role to the client device 103 with a “deny DHCP renew/request” rule at the commencement of an authentication procedure, the systems and methods described herein ensure that a race condition does not allow the client device to renew an IP address in an old segment of the network. Accordingly, the client device may avoid a possibly improper IP address in a segment of the network system in which the client device is no longer associated with or operating on.
摘要翻译：描述了用于在网络上的客户端设备的认证之后将适当的因特网协议（IP）地址分配给客户端设备的方法和系统。特别地，在开始客户端设备的认证过程时，角色与拒绝所有DHCP更新/请求的客户端设备相关联。通过在身份验证过程开始时，使用“拒绝DHCP更新/请求”规则向客户端设备103分配角色，本文所述的系统和方法确保竞争条件不允许客户端设备更新IP地址网络的旧段。因此，客户端设备可以避免在客户端设备不再与其相关联或在其上运行的网络系统的段中的可能不正确的IP地址。
