Table 3-36 System Options Elements
Field | Description | Data Input Notes |
---|---|---|
General Options | ||

Format: Field Range: none Default: 60000 |
Interval ICMP ping of all peer next-hops | If checked, an ICMP ping echo is sent to the next-hop of every remote peer every 2 minutes. This is useful for keeping switch address tables up-to-date. | Format: Checkbox Range: Checked (enabled), not checked (disabled) Default: Disabled |
IPFE Connection Reserved Ingress MPS Scaling | Percentage of DA-MP engineered ingress MPS used by each DA-MP when validating the reserved ingress MPS for a newly received floating IPFE connection. A newly received floating IPFE connection is rejected if the total connection reserved ingress MPS for fixed and already established floating IPFE connections would exceed the DA-MP's engineered ingress MPS, scaled by this value. This field is view-only; it cannot be user-configured. |
Format: Field Range: 30-100 percent Default: 50 percent |
Redirect Answer Processing Enabled | If checked, redirect notification response processing is enabled. If unchecked, redirect notification response processing is disabled. If disabled, redirect notification responses are passed through to the downstream peer. Redirect notifications are processed as follows:
|
Format: Checkbox Range: Checked (enabled), not checked (disabled) Default: none |
Redirect Application Route Table | Application route table instance used to process a redirected request. Note: If not configured, ART processing is skipped, and if configured, the ART is searched with the content of the redirect request message, similar to an ingress request. |
Format: List Range: none Default: none |
Redirect Peer Route Table | Peer route table instance used to process a redirected request. Note: If not configured, the PRT selection process is identical to the ingress request. |
Format: List Range: none Default: none |
Encode FQDN In Lower Case | Determines whether or not FQDNs should be encoded as configured or in all lower-case. | Format: Options Range: Yes, No Default: Yes |
* Excessive Reroute Onset Threshold | Excessive reroute alarm is raised when percentage of the total rerouted messages due to answer response and/or answer timeout to the total requests forwarded exceeds the onset threshold value. | Format: Field Range: 1-100 Default: 20 |
* Excessive Reroute Abatement Threshold | Excessive reroute alarm is cleared when percentage of the total rerouted messages due to answer response and/or answer timeout to the total requests forwarded is less than this abatement threshold for configured abatement time. The excessive reroute abatement threshold field value must be less than excessive reroute onset threshold field value. |

ETG Mode | Defines the type of message throttling supported when routing Request messages to connections associated with ETGs. Threshold - Threshold Mode is legacy mode, which configures the congestion level for ETGs and enforce the Requests based on congestion level of ETG. Limit - Limit Mode shapes the egress message rate according to the maximum message and pending transaction rate, the system discard policy, and the current mix of requests by message color and priority. |
Format: List Range: Threshold, Limit Default: Threshold |
