LinkTestRatio 

Controls the frequency of the ping test in relation to the link test. The ping test may be run at a lesser frequency to reduce network traffic.  

If this attribute is set to 1, packets are sent during every monitor cycle.  

If this attribute is set to 0, packets are never sent during a monitor cycle. Symantec does not recommend setting the value to zero. 

The agent determines link status without transmitting any ping packets. For other values greater than 1, packets are sent at a lower frequency. 

For example, if LinkTestRatio=2, then ping packets are sent out during every other monitor cycle. In other words, packets are sent out half as often than if LinkTestRatio were equal to one. 

Type and dimension: integer-scalar 

Default: 1 

NetworkHosts 

The NetworkHosts attribute is a list of hosts on the local network that are pinged to determine if the network connection is available. These must be IP addresses, and not host names. 

If you do not specify this attribute, the agent monitors the NIC by pinging the broadcast address on the NIC. If you specify one or more network hosts, and at least one host responds to a ping, the agent reports the MultiNICB resource online. The IP addresses for the NetworkHosts attribute must be on the same subnet as the other IP addresses for the MultiNICB resource. 

Type and dimension: string-vector 

Default: 0.0.0.0 

Example: "10.128.8.10, 10.128.8.45" 

NoBroadcast 

If set to 1, NoBroadcast prevents the agent from sending broadcast pings. ARP requests may still be generated.  

  Note   If no NetworkHosts are specified and NoBroadcast is set to 1, the agent cannot function properly. Symantec does not recommend setting NoBroadcast to 1.

Type and dimension: integer-scalar 

Default: 0 

OfflineTestRepeatCount 

Number of times the test is repeated if the interface status changes from up to down. For every repetition of the test, the next NetworkHosts attribute is selected in round-robin manner. At the end of this process, broadcast is performed if NoBroadcast is set to 0. A greater value prevents spurious changes, but increases the response time. 

Type and dimension: integer-scalar 

Default: 3 

OnlineTestRepeatCount 

Number of times the test is repeated if the interface changes from down to up. This helps prevent oscillations in the status of the interface. 

Type and dimension: integer-scalar 

Default: 3 

NetworkTimeout 

Timeout for ARP and ICMP packets in milliseconds. MultiNICB waits for the response to ICMP and ARP packets only during this time period. 

Assign NetworkTimeout a value in the order of tens of milliseconds, given the ICMP and ARP destinations must be on the local network. Increasing this value increases the time for failover. 

Type and dimension: integer-scalar 

Default: 100
