Enable Sharing Grouping - Extreme Networks ExtremeWare Command Reference Manual

Commands for Configuring Slots and Ports on a Switch

enable sharing grouping

enable sharing <port> grouping <portlist> {dynamic | algorithm {port-based
| address-based | round-robin}}
Description
This command enables the switch to configure static port load sharing or dynamic port load sharing.
When configuring dynamic port load sharing, LACP will be used to detect and set up for the remote
side's load sharing capabilities.

Usage Guidelines
On a stand-alone switch,
port specification, see "Modular Switch Numerical Ranges" or "Stand-alone Switch Numerical Ranges"
in Chapter 1.
Load sharing allows you to increase bandwidth and resilience between switches by using a group of
ports to carry traffic in parallel between switches. The sharing algorithm allows the switch to use
multiple ports as a single logical port or a "master" port. For example, VLANs see the load-sharing
group as a single logical port. The algorithm also guarantees packet sequencing between clients.
If a port in a load-sharing group fails, traffic is redistributed to the remaining ports in the load-sharing
group. If the failed port becomes active again, traffic is redistributed to include that port.
Load sharing must be enabled on both ends of the link, or a network loop will result.
While LACP is based on industry standard, this feature is supported between Extreme Networks
switches only. However, it may be compatible with third-party "trunking" or sharing algorithms. Check
with an Extreme Networks technical representative for more information.
Modular switch load-sharing groups are defined according to the following rules:
• The first port in the load-sharing group is configured to be the "master" logical port. This is the
reference port used in configuration commands. It can be thought of as the logical port representing
the entire port group.
• A master port can be a member of a Spanning Tree Domain (STPD), but the other ports assigned to a
load-sharing group cannot.

Specifies the master port for a loadsharing group.
Specifies one or more ports or slots and ports to be grouped to the master
port. On a modular switch, can be a list of slots and ports. On a stand-alone
switch, can be one or more port numbers. May be in the form 1, 2, 3-5, 2:5,
2:6-2:8.
Specifies dynamic sharing by using LACP.
Specifies sharing by port-based, address-based, or round-robin algorithms.
