Cisco Bug: CSCus85257 - ASA Connector - Provide Higher Layer Health Checks for CWS Tower

  • Cisco ASA 5500-X Series Firewalls

Known Affected Releases

9.3(2)

Description (partial)

Symptom:
The ASA may not failover to the backup CWS tower when the CWS tower is in a degraded state but remains responsive to ASA TCP health checks.  This may cause traffic interruption in the network environment when the ASA continues to redirect web traffic to the degraded tower.  This is an enhancement request to provide more granular health checking between the ASA and the CWS tower.

Conditions:
This can occur if the CWS tower is degraded (not down) but is still able to complete the 3-way TCP handshake with the CWS tower.
