Gateways and Devices workspace
The Gateways and Devices workspace displays status and
information that identify gateways and devices for a TCP/IP address
space. Use this workspace to monitor network devices that drop out
of Ready status and to monitor the link or route status of gateways.
This workspace is displayed by clicking on the Gateways and Devices
Navigator item.
Notes:
- If the address space being monitored is running on z/OS v1.9
or earlier, the values for this attribute group are retrieved using
SNMP.
- If the agent address space being monitored is running on z/OS
v1.10 or v.1.11, the route information in this workspace is retrieved
using the I/O control (IOCTL). Link or Interface attributes associated
with the Gateway are retrieved using SNMP.
- If the address space being monitored is running on z/OS v1.12
or later, the values for this attribute group are retrieved using
the I/O control (IOCTL) interface. Link or Interface attributes associated
with the Gateway are retrieved using the z/OS Communications Server
callable network management interfaces (NMIs).
- If you are viewing this workspace on an LPAR running z/OS 1.9
or earlier, the following attributes display as blank:
- Dynamic Route
- Network Route
- Route Status
- Route Type
- If you are viewing this workspace on an LPAR running z/OS 1.9,
the MTU Value attribute displays a value of zero (0).
- DVIPA reporting differs based on the level of z/OS running
in the address space being monitored.
- If the address space running z/OS v1.10 or earlier (SNMP data
collection), DVIPAs are reported in the Interfaces workspace.
- Under z/OS v1.11 and later (IOCTL and SNMP data collection), DVIPAs
are reported in the Gateways and Devices workspace. This workspace
is able to report a value for the Link or Interface Name attribute
for DVIPA routes.
- Under z/OS v1.12, (IOCTL and NMI data collection), the Link or
Interface Name attribute is blank for DVIPA routes If a row in the
Gateways table shows a value of blank for Link or Interface Name attribute
under z/OS v1.12 or later, then this row represents a DVIPA route.
The TCP/IP Gateways and Devices workspace displays data in two
table views, the TCPIP Devices Summary table and the TCPIP Gateways Summary table.
TCPIP Devices Summary table
The TCPIP Devices Summary table contains a row for each device
defined to the TCP/IP address space. Each row (or device) provides
the following types of information:
- Device name, address, and type
- Status (active, inactive, ready)
- Queue size
- Link name and type
- Network where device is attached
- Route type and status
- Interface Index
For a complete list of the attributes available in the TCPIP Devices
Summary table, and a brief description of each, see the TCPIP Devices Attributes help panel.
TCPIP Gateways Summary table
For monitored gateways, the TCPIP Gateways Summary table contains
a row for each gateway defined for the TCP/IP address space. Each
row (or gateway) provides the following types of information:
- Network address identifying the gateway
- First hop, which identifies the first router in the path to the
remote network
- Link or interface name associated with the gateway and its status
Note:
Under z/OS v1.12, (IOCTL and NMI data collection),
the Link and Interface Name attribute is blank for DVIPA routes If
a row in the Gateways table shows a value of blank for Link or Interface
Name attribute under z/OS v1.12 or later, then this row represents
a DVIPA route.
- Subnet mask and value identifying the subnetwork and subnodes
in the gateway host
- Route type and status
- MTU value
- Dynamic Route
- Network Route
- IP Version
- Interface Index
For a complete list of the attributes available in the TCPIP Gateways
Summary table, and a brief description of each, see the TCPIP Gateways Attributes help panel.
