Description

The SET FACILITY command sets the router load balancing and quorum characteristics of a facility.

Qualifiers

/BROADCAST_MINIMUM_RATE=Bps /BROADCAST_MINIMUM_RATE=1000

/BROADCAST_MINIMUM_RATE=nnnn specifies the minimum rate (in bytes per second) to which flow control can reduce broadcast traffic on outgoing facility links from the node concerned.

For example, consider a facility has 100 frontends and 99 of them are able to receive data at a rate of 2KB per second, but one frontend has become congested and is not able to receive any. This can result in all the frontends slowing down to the rate that the slowest can accept.

Specifying /BROADCAST_MINIMUM_RATE=2000 on the router ensures that the 99 frontends receive their broadcasts, and that RTR attempts to send the broadcasts to the congested frontend. However, broadcasts for the congested frontend are discarded (if absolutely necessary) rather than slowing down all frontends to the rate that the slowest can accept.

Specifying /BROADCAST_MINIMUM_RATE without a value gives a default 1000 bytes per second; if you do not use the qualifier then the minimum is zero.

/QUORUM_THRESHOLD=n /QUORUM_THRESHOLD=0

/QUORUM_THRESHOLD=n sets the minimum number of nodes/role combinations that have to be reachable to declare the configuration quorate.

RTR Command Line Interface 6–109
