Cisco Bug: CSCup83180 - DOC: No Directly Connected Subnet Extention with Inter-site Clustering
Sep 13, 2019
- Cisco ASA 5500-X Series Firewalls
Known Affected Releases
Symptom: Adaptive Security Appliance (ASA) configuration guide contains the following guideline for extending the data VLANs with inter-site clustering: "For transparent mode, do not extend the data VLANs between switches at each site; a loop will occur. Data traffic must be routed between the two sites." This documentation defect is filed to change this wording as such: "For Spanned EtherChannel mode, do not extend the data VLANs which are directly connected to the ASA cluster between sites; a loop (transparent mode) or duplicate MAC and IP addresses (routed mode) will occur. Any extended data VLANs must be separated from the cluster by a router." Conditions: Using inter-site clustering where data VLANs are extended between different sites.
