  • Etherchannel & Highly Available Cluster Multiprocessing (HACMP) in AIX V5.2
    EtherChannel & Highly Available Cluster Multiprocessing (HACMP) in AIX V5.2 How-to and Test Experiences Abstract: This document gives tips and a working example of how to a Highly Available Cluster Multiprocessing (HACMP) user could implement EtherChannel with HACMP. Support for this combination was announced in May, 2004. Authors: Shawn Bodily (HACMP) and Cindy Young (EtherChannel) of IBM pSeries Advanced Technical Support and Michael Herrera (HACMP) of IBM pSeries AIX Support Introduction IBM AIX pSeries administrators have expressed interest in combining these components for several reasons. Those accustomed to other software availability solutions object to HACMP’s additional “standby” adapter. With EtherChannel, HACMP setups could mask the standby adapter giving an outward appearance familiar to these users. Other users like the aggregated bandwidth, load balancing, or high availability benefits of EtherChannel. The result is a lower cost, high performance network that is also popular as a high speed private (non-switch) interconnect between machines. In this test, we successfully implemented a “single adapter network” HACMP IP Address Takeover (IPAT) with the EtherChannel function included in AIX V 5.2. The EtherChannel was responsible for providing local adapter swapping – outside of HACMP. HACMP has no knowledge of EtherChannel and is completely independent. While a single adapter network is normally not ideal, EtherChannel makes this okay because there are multiple physical adapters within the single EtherChannel pseudo device. Thus, we could safely ignore the insufficient adapter warning messages posted during cluster synchronization. Our configuration consisted of a rotating resource group with a single adapter network using IP aliasing. Our testing proved to be beneficial in simplifying the HACMP setup.

We refer to the adoption proposed to be part of the IEEE 802.11be Extremely High of multi-link communications, which represents a paradigm Throughput (EHT) amendment.

  • Application Notes
    A Sample Configuration with Design Guidelines for Link Aggregation Between Avaya™ P580/P882 Gigabit Ethernet Switch Hunt Groups and Cisco EtherChannel - Issue 1.0 Abstract These Application Notes describe a sample Hunt Group/EtherChannel Link Aggregation Group (LAG) configuration between an Avaya™ P882 Gigabit Ethernet switch and a Cisco Catalyst 6509 switch. Design guidelines for deploying LAG in a mixed Avaya/Cisco infrastructure are included as an aid for network designers. A sample configuration diagram has been included along with provisioning notes. These Application Notes were created as a result of field requests for information on interoperability between Avaya P580/P882 Hunt group trunks and Cisco EtherChannel. GAK; Reviewed: Solution & Interoperability Test Lab Application Notes 1 of 15 WCH 7/18/2003 ©2003 Avaya Inc. All Rights Reserved. cislaginterop.doc 1. Introduction The Avaya™ P580/P882 Gigabit Ethernet Switch Hunt Group feature aggregates multiple switch ports together, combining the bandwidth into a single connection. This feature is normally deployed between switches to provide added bandwidth and fault tolerance. If one segment in a hunt group fails, the remaining active members will service the traffic for that segment. The Hunt Group Load-Sharing feature (enabled by default) distributes traffic load among the hunt group members for improved throughput performance. Hunt group member ports can be configured using various trunk modes including IEEE 802.1Q, Multi-layer, 3Com and Clear. Hunt group ports may also be assigned a router IP interface for layer 3 forwarding. The Avaya™ Hunt Group feature is a manual (or static) implementation of link aggregation. This means the feature does not support dynamic LAG configuration or binding via some standard or proprietary protocol.
