Usage guidelines

This command is available only in IRF mode.

For IRF link auto-recovery to take effect, you must first enable IRF link status detection.

IRF link auto-recovery enables the system to recover failed IRF links automatically.

The undo form of this command is only for debugging purposes. You must enable IRF link auto-recovery when you finish debugging the function.

When you change the operating mode from IRF to standalone, the undo irf link-status auto-recovery enable command configuration is lost, whether or not you have saved the configuration.

IRF probe commands -- irf link-status detect enable

| NOTE: Support for this command depends on the device model.

Use irf link-status detect enable to enable IRF link status detection.

Use undo irf link-status detect enable to disable IRF link status detection.

Syntax

irf link-status detect enable

Parameters

cascade-port interface-name: Specifies a cascade port, which is a Layer 2 aggregate interface that connects a PEX. This option is supported only by the parent fabric.

interface interface-name: Specifies an extended port by its internal interface name in the IRF 3.1 system.

pex-local-ifindex ifindex: Specifies an extended port by its local interface index. To obtain PEX local interface indexes, use the display system internal pex ifindex command on a PEX. If the extended port is not successfully created on the parent fabric, you must use this option instead of interface interface-name to specify an extended port. This option is supported only by the parent fabric.

Usage guidelines

In an IRF 3.1 system, the physical interfaces on PEXs are called extended ports, except for the physical interfaces aggregated in the upstream ports.

If you do not specify any parameters, this command displays the records for all extended ports created on the parent fabric.

Usage guidelines

An upstream port is a Layer 2 aggregate interface automatically created on a PEX for parent connection. If the PEX has multiple candidate upstream ports connected to a parent fabric or to multiple parent fabrics, it selects one of the ports as the upstream port. The parent fabric connected to the selected upstream port is the parent fabric of the PEX. The upstream port selection rule is as follows:

1. Compares upstream port priorities. The upstream port priority is 0 by default and is not user configurable in the current software version.

2. Compares the MAC addresses of the peer ports. The lower the MAC address of the peer port, the higher the priority of the candidate upstream port. A candidate upstream port with higher priority is more likely to be the upstream port.

After upstream port selection, the PEX sends PE CSP packets only through the selected upstream port and ignores the PE CSP packets received from other candidate upstream ports.

Execute this command on a PEX. If the PEX has joined an IRF 3.1 system, use the switchto pex command on the parent fabric to log in to the CLI of the PEX.
