ADS policy considerations
The following are considerations for setting the ADS policy:
• In cascading configurations, you should set the ADS policy on the AG module that directly
connects to the servers.
• ADS policy can be enabled or disabled independent of status of other AG policies.
• The ADS policy is not currently supported with device-based mapping.
Upgrade and downgrade considerations for the ADS policy
Downgrading to Fabric OS v6.3.0 or earlier is supported.
Upgrading from v6.3.0 to v6.4.0 or downgrading from v6.4.0 to v6.3.0 will not change the APC
policy settings.
Automatic Port Configuration policy
APC provides the ability to automatically discover port types (host, target, or fabric) and dynamically
update the port maps when a change in port-type connection is detected. This policy is intended for
a fully hands-off operation of Access Gateway. APC dynamically maps F_Ports across available
N_Ports so they are evenly distributed.
How the APC policy works
When the APC policy is enabled and a port on AG is connected to a Fabric switch, AG configures the
port as an N_Port. If a host is connected to a port on AG, then AG configures the port as an F_Port
and automatically maps it to an existing N_Port with the least number of F_Ports mapped to it.
When the APC policy is enabled, it applies to all ports on the switch.
