TRLE = trl_element STATUS = trle_status CONTROL = lnctl

Explanation

VTAM® issues this message as part of a message group in response to any of the following commands:
  • A DISPLAY ID command for a PU that supports an APPN host-to-host connection.
  • A DISPLAY ID command for a PU that supports an XCF connection.
  • A DISPLAY TRL command when the TRLE operand is not specified.

trl_element is the name of an element in the active transport resource list (TRL).

When lnctl is TCP, the name of the TRL element (TRLE) given by trl_element is dynamically generated by VTAM. The first three characters of the name are always IUT and the fourth character of the name indicates the device type according to the following list:

C
CDLC
H
Hyperchannel
L
LCS
S
Samehost
W
CLAW
X
CTC

When lnctl is ROCE, the name of the TRLE given by trl_element is dynamically generated by VTAM. The first three characters of the name are always IUT, the fourth character represents the port number (1 or 2), and the last four characters represent the Peripheral Component Interconnect Express® (PCIe) function ID (PFID) used by the IBM® 10GbE RoCE Express feature represented by trl_element.

trle_status is the resource status code that indicates the current status of the TRL element. If trle_status is ****NA****, then the TRL major node with the TRLE named on the PU definition must be activated. See Resource Status Codes and Modifiers inz/OS Communications Server: IP and SNA Codes for a description of these status codes.

lnctl is the line control setting for trl_element, and can be one of the following:
MPC
multipath channel
ROCE
RDMA (Remote Direct Memory Access) over Converged Ethernet
TCP
transmission control protocol
XCF
cross-system coupling facility
