Symptoms

The LTM SASP monitor marks pool members down, whose address include non-default route domains.

Impact

Pool members with non-default route domains will never be marked up by the SASP monitor.

Conditions

1. Using the SASP health monitor to monitor a pool or pool member. 2. The address of the pool member includes a non-default route domain, such as: ltm pool rd_test { members { test_1:http { address 12.34.56.78%99 } } monitor my_sasp }

Workaround

Do not specify non-default route domains in the addresses of pool members monitored by the SASP health monitor. The SASP protocol does not support the use of route domains in member addresses. Thus, the SASP GWM (Global Workload Manager) will ignore route domain information included in the member addresses when registered by the SASP monitor in BIG-IP, and will report the status of members using addresses without route domains. Therefore, even with a fixed version of the SASP monitor, BIG-IP LTM administrators must be careful to avoid configuring multiple pool members with the same address except for different route domains, to be monitored by the SASP monitor. If case of such a configuration error, the status of the member reported by the SASP GWM may not accurately reflect the status of one or more of the pool members with matching IP addresses.

Fix Information

The LTM SASP monitor will correctly report the status of pool members configured with addresses that include a non-default route domain, if the SASP GWM is monitoring members with matching addresses (minus route-domain information).
