Using link aggregation, network traffic is dynamically distributed across ports, so administration of what data actually flows across a given port is taken care of automatically within the aggregated link.
Note: The NAB configures 802.3ad link aggregation on TIBCO Messaging Appliance P-7500 systems as Active mode only. Thus, third-party switches that support 802.3ad link aggregation can be configured as either Active or Passive mode when connected to the TIBCO Messaging Appliance P-7500 system.The link aggregation standard provides inherent, automatic redundancy on point-to-point links. In other words, if one of the multiple ports used in a link fails, network traffic is dynamically redirected to flow across the remaining good ports in the link. The redirection is fast and triggered when a switch detects the physical failure. The switch then sends the data to the new port location, and the network continues to operate with virtually no interruption.By default through the setup Privileged EXEC command, the physical interfaces on the NAB are all configured as ’lag1’ upon completing the initial software configuration procedure described in TIBCO Messaging Appliance P-7500 Getting Started.The NAB of a P-7500 system also supports multiple IP Addresses on an interface in addition to 802.3ad link aggregation. To assign independent IP addresses to every port of the NAB (that is, have no LAG configured), or have a mixture of some NAB ethernet ports grouped into a single LAG and the remaining ports independently addressed, refer to Chapter 8, Configuring IP Interfaces and Addresses.
