Port swapping

Registered listeners

To display registered listeners for link incidents, connect to the switch, log in as user, and enter one

of the following commands:

•

For the local switch:

ficonShow lirr

•

For all switches defined in the fabric:

ficonShow lirr fabric

Example of LIRR output:

switch_4:FID4:admin> ficonshow lirr

The Local LIRR database has 3 entries

Current LIRR device port number: <XX>

When you configure an LIRR entry and it is current, it is marked with

-C

. If the Management Server

marks an entry as current based on order, it is marked with

-C

. If the Management Server marks

an entry as secondary, it is marked with

-S

If the LIRR is configured then the

<XX>

indicates a valid port number. Otherwise, the line will

display the following:

Current LIRR device port number is not configured.

Node identification data

To display node-identification data, connect to the switch, log in as user, and enter any of the

following commands:

•

For the local switch:

ficonShow switchrnid

•

For all switches defined in the fabric:

ficonShow switchrnid fabric

•

For all devices registered with the local switch:

ficonShow rnid

•

For all devices registered with all switches defined in the fabric:

ficonShow rnid fabric

FRU failures

FRU failure information is no longer stored on the switch. FRU failures are sent to the host operator

console.

Port swapping

If a port malfunctions, or if you want to connect to different devices without having to re-wire your

infrastructure, you can move a port’s traffic to another port (

swap ports

) without changing the I/O

Configuration Data Set (IOCDS) on the mainframe computer.

ATTENTION

Ports that have been swapped cannot be moved to another logical switch.
