TCPIP Gateways Attributes
Use the TCPIP Gateways attributes to monitor the gateways defined to a selected address space.
Collection Time The time and date of the data sampling. This time is displayed in the following format:
mm/dd/yy hh:mm:ss (Tivoli Enterprise Portal) or yy/mm/dd hh:mm:ss (3270)
Where:
- mm = Month
- dd = Day of the month
- yy = Year
- hh = Hour
- mm = Minute
- ss = Seconds
The stored format is a string no longer than 16 characters in the
format CYYMMDDHHMMSSmmm
(as in 1020315064501000 for
03/15/02 06:45:01) where:
- C = Century (0 for 20th, 1 for 21st)
- Y = Year
- M = Month
- D = Day
- H = Hour
- M = Minute
- S = Second
- m = Millisecond
Dynamic Route Indicates whether the route used by this gateway was dynamically created (valid for IPv4 only). This value is stored as an integer and displayed as a string. Valid values are:
- 0 = No
- 1 = Yes
- 2 = (blank)
First Hop (Deprecated) The first router in the path to the remote host. The format is an alphanumeric string no longer than 15 characters.
First Hop The first router in the path to the remote network. The format is an alphanumeric string no longer than 45 characters. This special value may be displayed as follows:
<direct> - First Hop is a host IP address.
Host Name The name of the TCP/IP stack. The format is an alphanumeric string no longer than 255 characters.
Interface Index The interface index associated with this gateway. The format is an unsigned integer.
IP Version The IP version of the route used by this gateway. This value is stored as an integer and displayed as a string. Valid values are:
- 0 = IPv4
- 1 = IPv6
Link or Interface Name The link or interface name associated with this gateway (router). The format is an alphanumeric string no longer than 16 characters.
Notes:
- This attribute is not available under z/OS® v1.12 if Interface Statistics data collection has been disabled.
- Under z/OS v1.12, this 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.
Link or Interface Status The status of the gateway link or interface, which indicates if the link is ready or not ready. If a link drops out of Ready status, you might lose connectivity to crucial network resources, and you might not be able to access needed applications. The gateway link can be in one of the following states:
- Ready
- Down
- Testing
- DAD_Pending
Notes:
- This attribute is not available under z/OS v1.12 if Interface Statistics data collection has been disabled.
- Under z/OS v1.12, this attribute is blank for DVIPA routes. If a row in the Gateways table shows a value of blank for Link or Interface Status attribute under z/OS v1.12 or later, then this row represents a DVIPA route.
MTU Value The maximum transmission unit (MTU) in bytes for the route. The format of this is an integer with a valid value of up to 65,535.
Network Address (Deprecated) The network address of this gateway. The format is an alphanumeric string no longer than 15 characters.
Network Address The network address of this gateway. The format is an alphanumeric string no longer than 45 characters. Special values may be displayed as follows:
- Defaultnet - The Network Address is a host IP address.
- Default - The Network Address is 0.
Link-local IPv6 addresses are displayed in the following format:
FE80::<interface ID>%<interface name>
Network Route Indicates whether the route used by this gateway was defined as a network route. This value is stored as an integer and displayed as a string. Valid values are:
- 0 = No
- 1 = Yes
- 2 = (blank)
Origin Node The unique identifier for the TCP/IP stack being displayed. The format is an alphanumeric string no longer than 32 characters.
Packet Size (Deprecated) The length of the packet in which the PING command sends the ECHO request message. The format is an alphanumeric string no longer than eight characters.
Route Status The status of route used by this gateway. This value is stored as an integer and displayed as a string. Valid values are:
- 0 = (blank)
- 1 = Active
- 2 = Inactive
Route Type The type of route used by this gateway. This value is stored as an integer and displayed as a string. Valid values are:
- 0 = (blank)
- 1 = Other
- 2 = Static
- 4 = ICMP
- 8 = RIP
- 13 = OSPF
- 129 = Router Advertisement
- 130 = Replaceable Static
Subnet Mask (Deprecated) The 32-bit mask for the subnetwork address in the IP address host portion. The format is an alphanumeric string no longer than 15 characters.
Subnet Mask The 32-bit (for IPv4 addresses) or 128-bit (for IPv6 addresses) mask for the subnetwork address in the IP address host portion. The format is an alphanumeric string no longer than 45 characters.
The following special values are displayed:
- <none> - Subnet Mask contains zeros
- HOST - Subnet Mask is a host IP address
Subnet Value (Deprecated) The subnet identifier. A subnet composes a group of nodes within the same network ID. The format is an alphanumeric string no longer than 15 characters.
Subnet Value The subnet identifier. A subnet composes a group of nodes within the same network ID. The format is an alphanumeric string no longer than 45 characters.
System ID The SMF system ID. The format is an alphanumeric string no longer than 4 characters
TCPIP STC Name The name of the TCP/IP job. The format is an alphanumeric string no longer than 8 characters.
