Behavior Of Kill Threshold And Retry_dis For Primary Connections (Doc ID 1211255.1)

Goal

This note aims to provide an understanding of the behaviour of the following scenario based on a given Network element configuration.

Configuration details:
1. Cartridge/Network element name = Alcatel Apollo cartridge (ALA8618IN_WSTR2_R1_0_0)
2. Network element configuration in ASAP, spawn threshold = 1
3. Kill threshold = 0
4. DISABLE_PORT_ON_LOGIN on NE = 1
5. Number of devices = 15
6. Parameter HOSTNAME is local for each device and may contain different IP addresses.
7. ORDER_TIMEOUT = 0
8. RETRY_TIME_INTERVAL = 120
9. NUM_TIMES_RETRY = 5
10. IO_ASDL_RETRY = 1
11. PORT_ENABLE_TIMER = 600

Specific questions:
1. What would happen if connection is being established with Apollo Network element for the first time and the host (where primary connection is mapped to) is facing an outage? Will auxiliary connections be attempted even though the primary connections fail and disables?


2. More importantly what would happen in a scenario where more than one devices are connected and active, and suddenly primary connection device receives a RETRY_DIS or loss in connection with its host? Since the kill threshold value is 0 does that mean the primary connection will never be killed by ASAP? Will it always be active and would there be a good chance of RETRY_DIS occurring over a long duration? What would be the behavior in ASAP in such a scenario?

What will happen to primary connection? What would happen to auxiliary connections?
