The per-context threshold of an IP Pool is the value for currently available per-context addresses, as reported in rbnIpPoolContextAvailable, which causes a trap and/or log message to be generated when this value is reached. This is a falling threshold, so a trap and/or log message will only be sent on a transition of the value of available addresss from (rbnIpPoolContextThreshold+1) addresses to rbnIpPoolContextThreshold addresses. Additionally, the action of sending the trap and/or log message is subject to the values of rbnIpPoolContextSendTrap and rbnIpPoolContextLogMessage. A value of zero means there is no per-context threshold.
