Avaya P882 User Manual

A Sample 802.1Q Hunt Group Trunk Configuration Between an Avaya™ P882 Gigabit Ethernet Switch and Servers with Intel Dual Port Server Adapters - Issue 1.0

Abstract

These Application Notes describe a sample Link Aggregation Group (LAG) configuration between two Windows 2000 Servers: one equipped with an Intel PRO/100+ Dual Port Server Adapter and the other an Intel PRO/1000MT Dual Port Server Adapter. Each adapter is connected to an Avaya™ P882 Gigabit Ethernet switch via a separate 802.1Q Hunt Group Trunk. A sample configuration diagram has been included along with all of the necessary provisioning steps. These Application Notes were created as a result of field requests for information on interoperability with Intel Dual Port Server Adapters.

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. These Application Notes describe a configuration where a hunt group is deployed between a switch and a server to provide similar bandwidth and fault tolerance advantages. If one segment in the hunt group fails, the remaining active members will service the failed segment traffic. The Hunt Group LoadSharing feature (enabled by default) distributes traffic load amongst the hunt group members for improved performance. A hunt group can be configured as an 802.1Q trunk or as a clear access link and associated with or without a router interface address.

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. Examples of such protocols include Link Aggregation Control Protocol (LACP) for dynamic 802.3ad and Cisco’s Port Aggregation Protocol (PAgP) for dynamic EtherChannel negotiation. It is possible to configure Avaya Hunt Groups to interoperate with third-party vendors. Forcing a LAG to be formed statically with a third-party vendor device without dynamic protocol negotiation is normally used for interoperability.

Enterprise-level servers are often deployed with a dual port Network Interface Card (NIC), also referred to as an adapter, to improve application response time and availability. Most dual port adaptor vendors provide the option to team both ports together for link aggregation via 802.3ad, EtherChannel or other proprietary mechanism.

These Application Notes discuss how the Avaya Hunt Group feature and load-sharing algorithm can be combined with Intel Dual Port Server Adapters implementing either static FastEtherChannel (FEC)/LAG or static GigabitEtherChannel(GEC)/LAG with 802.1Q enabled. The specific Intel NIC cards validated were the Intel PRO/100+ Dual Port Server Adapter and PRO/1000MT Dual Port Server Adapter. Figure 1 shows the sample configuration that was verified.

Notes: It is only necessary to configure VLAN information for the first port that will be added to the Hunt Group. When the first port is added to the Hunt Group, it is designated as the “Base Port” and all other member ports will assume the identity of the base port. Unknown unicast and broadcast traffic is flooded on the base port only. If multiple VLANs are being statically mapped (via the CLI) to Hunt Group member ports, then each member port must be configured with the VLANs individually before configuring them as Hunt Group members.
