HP 6125XLG R2306-HP 6125XLG Blade Switch IRF Command Reference - Page 24

An IRF fabric has only one IRF domain ID. You can change the IRF domain ID with the following commands: irf domain, mad enable, mad arp enable, or mad nd enable. The IRF domain IDs configured by using these commands overwrite each other. Examples # Enable LACP MAD on Bridge-Aggregation 1, a Layer 2 dynamic aggregate interface. system-view [Sysname] interface bridge-aggregation 1 [Sysname-Bridge-Aggregation1] link-aggregation mode dynamic [Sysname-Bridge-Aggregation1] mad enable You need to assign a domain ID (range: 0-4294967295) [Current domain is: 0]: 1 The assigned domain ID is: 1 MAD LACP only enable on dynamic aggregation interface. Related commands irf domain mad exclude interface Use mad exclude interface to exclude a physical network port from being shut down when the IRF fabric transits to the Recovery state upon detection of a multi-active collision. Use undo mad exclude interface to restore the default MAD action on a physical network port. Syntax mad exclude interface interface-type interface-number undo mad exclude interface interface-type interface-number Default All physical network ports but the IRF physical ports and console ports shut down when the IRF fabric transits to the Recovery state. Views System view Predefined user roles network-admin Parameters interface-type interface-number: Specifies a port by its type and number. Usage guidelines When MAD detects that the IRF fabric has split into two or more identical active IRF fabrics, it sets one of the IRF fabrics to the Detect state and other IRF fabrics to the Recovery state. • The Detect-state IRF fabric is active and can continue to forward traffic. • The Recovery-state IRF fabrics are inactive. MAD shuts down all their physical ports except the IRF ports and the ports manually configured to not shut down. If a port must be kept in up state for special purposes such as Telnet connection, exclude it from the shutdown action. To avoid incorrect traffic forwarding, HP recommends not excluding any ports except the ports used for Telnet and MAD. 21
