Irf Isolate Member - HPE FlexNetwork 10500 series Command Reference Manual

An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using 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.
In an MDC environment, the irf domain command is available only on the default MDC. The mad
enable, mad arp enable, and mad nd enable commands are available on all MDCs. If you change
the IRF domain ID in one MDC, the IRF domain IDs in all other MDCs change automatically.
Examples
# Set the IRF domain ID to 30.
<Sysname> system-view
[Sysname] irf domain 30

Usage guidelines
This command is supported only in IRF mode.
CRC errors or traffic storms occur if an IRF member device tags inter-chassis packets with a valid
unused member ID. This issue is typically caused by poor-quality fiber modules, fibers, or cables on
IRF links.
To avoid CRC errors or traffic storms, isolate the unused member IDs in the valid member ID range.
When an unused member ID is isolated, the member devices will drop all packets that are tagged
with the member ID.
Before you assign an isolated member ID to a new member device, you must remove the isolation
setting for the member ID by using the undo irf isolate member command.
Examples
# Isolate IRF member ID 3.
<Sysname> system-view
[Sysname] irf isolate member 3
