3.1.2.6 Configuration of individual mode

Table 3.6 shows description of parameters for each mode. These values apply to the whole system. However, these values cannot convert to unit of the virtual interface or redundancy mode. This configuration is not necessary when using the default value.

The followings are description of each of the content.

Transfer path monitoring interval (K-1)

Specify the transfer path monitoring interval in seconds. The range of the intervals that can be specified is from 0 to 300 sec. If "0" is specified, it will not monitor the transfer path. Initially, it is set to 5 seconds. will not monitor the transfer path. Initially, it is set to 5 seconds. The transfer path monitoring interval is set using "hanetparam" command with -w option. This feature is available for Fast switching mode and Fast switching/RIP mode.

The number of constant monitoring prior to message output (K-2)

Specify the number of times for monitoring before outputting the message (No: 800 or 801) if the message needs to be output as a transfer path failure is detected. The effective range of the numbers which can be specified is from 0 to 100. If "0" is specified, it will not output a message. Initially it is set to 0 (does not output any message). using "hanetparam" command of -m option. Note that this feature is only available for Fast switching mode and Fast switching/RIP mode.

The number of constant monitoring prior to switching cluster (K-3)

Specify whether or not to switch over the cluster if a failure occurs on a whole transfer path of the virtual interface. The effective range of the numbers is from 0 to 100. it will not switch the cluster. When configuring to switch the cluster, set how many times it repeatedly monitors. The range is from 1 to 100. Initially, it is set to 5, meaning that a cluster failover is triggered after continuously detecting the same failure 5 times. This feature is specified using "hanetparam" command with -i option. This feature is available only for Fast switching and Fast switching/RIP mode.

Switching cluster immediately after starting (K-4)

Specify whether or not to switch the cluster immediately after the cluster starts up. Configure this if a failure occurs in entire transfer path of the virtual interface before the system starts up. The values which can be specified are either "on" or "off". If "on" is selected, cluster is switched immediately after the userApplication starts up. On the other hand, if "off" is selected, the cluster is not switched even after the userApplication starts up. As an initial value, it is set to "off". This setting is specified using "hanetparam" command with -c option. This is available for Fast switching and Fast switching/RIP mode.

Outputting message (monitoring the physical interface) (K-5)

Configure whether or not to output a message when the status of the physical interface changes (detecting a failure in transfer path or transfer path recover) in the virtual interface. The values which can be specified are either "on" or "off". If "on" is selected, a message (message number: 990, 991, 992) is outputted. If "off" is selected, a message is not outputted. Initially, it is set to "off". This setting is specified via "hanetparam" command with -s option. This is available for Fast switching and Fast switching/RIP mode.

Standby patrol monitoring period (K-6)

Specify the monitoring interval (in seconds) of operational NIC for standby patrol function. The values which can be specified are from 0 to 100. If "0" is specified, it will not run monitoring. Note if the user command function (using user command when standby patrol fails or detects recovery) is enabled, do not set the parameter to "0". If the parameter is set to "0", the user command function will not work. Initially, the parameter is set to 15 (seconds). This setting is specified via "hanetparam" command with -p option. This configuration is available for NIC switching mode with standby patrol function is enabled.

The number of constant standby monitoring prior to outputting message (K-7)

When a failure is detected in a transfer path using the standby patrol function, a message will be outputted to inform the failure. In this section, specify how many times to monitor until the message (message number: 875) is outputted. The values which can be specified are from 0 to 100. If "0" is selected, it stops outputting a message and disables monitoring using the standby patrol function. Note if the user command function (using user command when standby patrol fails or detects recovery) is enabled, do not set the parameter to "0". If the parameter is set to "0", the user command function will not work. Initially, the parameter is set to 3 (times). This configuration is specified via "hanetparam" command with -o option. This is available in NIC switching mode, which uses the standby patrol function. Using this option, the number of monitoring times doubles immediately after the standby patrol starts.

Deactivating the standby interface (K-8)

Specify how the standby interface is deactivated. The values which can be specified are either "plumb" or "unplumb". If "plumb" parameter is specified, the standby interface is deactivated and sets "0.0.0.0" for the IP address. With this parameter, it is possible to use "INTERSTAGE Traffic Director" as a high-level application. On the other hand, selecting "unplumb" deactivates the standby interface and then it sets to unused status. Initially, the parameter is set to "unplumb".
If you make the Solaris container network highly reliable through NIC switching mode, it is necessary to specify "plumb".
This configuration is specified by "hanetparam" command with -d option. This is available exclusively for NIC switching mode.

Monitoring period (K-9)

Specify the monitoring period in seconds. The values which can be specified are from 1 to 300. The default value is 5 (seconds). This configuration is specified by "hanetpoll on" command with -s option. This feature is available for RIP, Fast switching/RIP, NIC switching and GS/SURE linkage mode.

The number of monitoring (K-10)

Specify the number of monitoring times. The values which can be specified are from 1 to 300. The default value is 5 (times). This configuration is specified using "hanetpoll on" command with -c option. This feature is available for RIP, Fast switching/RIP, NIC switching and GS/SURE mode.

The number of retries until router monitoring stops (K-11)

Specify the number of retries in order to stop monitoring when a failure is detected. The values which can be specified are from 0 to 99999. Initially, the value is set to 5 (times). If not to stop monitoring, set this value to "0". This configuration is specified using "hanetpoll on" command with -r option. This feature is available for RIP, Fast switching/RIP mode.

Recovery monitoring period (K-12)

Specify the monitoring period when a failure is detected by router monitoring function for RIP mode and Fast switching mode, and monitoring the remote host by GS/SURE linkage mode. The values which can be specified are from 0 to 300. The default value is 5 (seconds). This configuration is assigned via "hanetpoll on" command with -b option. This feature is available for RIP, Fast switching/RIP, and GS/SURE linkage mode.

Cluster switching (K-13)

Specify whether or not to switch the node when a failure occurs to every transfer paths.
yes: Switch nodes when a failure occurs to a whole transfer paths.
no: Does not switch nodes when a failure occurs to a whole transfer path.
The default parameter is "yes". This configuration is specified by "hanetpoll on" command with f. This feature is available for RIP, Fast switching/RIP, NIC switching, and GS/SURE linkage mode operating as a cluster.

Link up waiting period (K-14)

In NIC switching mode, specify the time period (in seconds) until the HUB to links up after monitoring starts. The values which can be specified are from 1 to 300. If this option is not specified, then the default value is used. Initial value is set to 60 (seconds). If the value is less than the product of monitoring period and monitoring times (monitoring period X monitoring times), then the value is ignored and ends up using the value of the product of monitoring period and monitoring times. This configuration is specified by "hanetpoll on" command with -p option. This feature is available for RIP, Fast switching/RIP, NIC switching and GS/SURE linkage mode.
