sam-aes-threshold
Configures the number of Ethernet device transmit and receive errors allowed before the primary SAM switches to the backup SAM.
Syntax: [no] sam-aes-threshold threshold
threshold
Specifies the number of reported transmit and receive errors allowed on the Ethernet device before triggering a primary SAM switch to its backup SAM. Valid Values: 0 - 4294967295. Default Value: 3.
Description: The Server Attached Module (SAM) acts as a proxy for any communications between the primary route controller and all other modules. A primary SAM will switch to its backup when the number of transmit and receive errors reported by the Ethernet device exceeds the configured threshold during a single discovery period.
IPriori passes messages between the route controller and other modules via the Primary SAM. The IPriori module discovery protocol monitors transmit and receive errors reported by the Ethernet device. The number of receive errors within a 3 second time period is computed. If this computed error count exceeds the configured threshold, the primary SAM flips to the backup SAM. The sam-aes-threshold command in Configuration mode configures the number of errors within the 3 second time period that would cause a flip from the primary SAM to the backup SAM.
Use the sam-aes-threshold command to specify the number of errors reported on the Ethernet device before the primary SAM switches to the backup SAM.
Use the no sam-aes-threshold command reset the threshold to the default value.
Factory Default: Threshold = 3.
Command Mode: Global Configuration.
Example 1: In the following example the Ethernet error threshold is set to 4 using the sam-aes-threshold command. The current value is displayed using the show server verbose command:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#sam-aes-threshold 4
router(config)#end
router#show server verbose
