Automatic Port Configuration policy 3 ADS policy considerations The ADS policy can be enabled or disabled independent of status of other policies. Automatic Port Configuration policy The automatic Port Configuration (APC) policy is disabled by default. APC provides the ability to automatically discover port types (host vs. fabric) and dynamically update the routing maps when a new connection is detected. This policy is intended for a complete hands-off operation. APC dynamically maps internal ports (F_Ports) to available external ports (N_Ports) so they are evenly distributed. For example, when a port on the module is connected to a fabric switch, the module configures the port as an external port. If a host is connected to a port on the FC SAN Module, then it determines that it is connected and configures the port as an internal port and automatically maps it to an existing external port with the least number of internal ports mapped to it. How the APC policy works When the APC policy is enabled, it applies to all ports on the switch. Enabling the APC policy is disruptive and erases all existing port mappings. Therefore, before enabling the APC policy, you must disable the FC SAN Module. When you disable the APC policy, the external port (N_Port) configuration and the port mapping revert back to the default factory configurations for that platform. It is recommended that you save the current configuration file using the configupload command in case you might need this configuration again. Enabling and disabling the APC policy Use the following steps to enable and disable Automatic Port Configuration policy. Enabling APC policy 1. Connect to the FC SAN Module and log in using an account assigned to the admin role. 2. Enter the switchdisable command to ensure that the module is disabled. 3. Enter the configupload command to save the module's current configuration. 4. Enter the ag --policyenable auto command to enable the APC policy. switch:admin> ag --policyenable auto All Port related Access Gateway configurations will be lost. Please save the current configuration using configupload. Do you want to continue? (yes, y, no, n): [no] y 5. At the command prompt, type Y to enable the policy. The switch is ready; a reboot is not required. Disabling APC policy 1. Connect to the FC SAN Module and log in using an account assigned to the admin role. 2. Enter the switchdisable command to ensure that the module is disabled. 3. Enter the configupload command to save the module's current configuration.

Automatic Port Configuration policy
3
ADS policy considerations
The ADS policy can be enabled or disabled independent of status of other policies.
Automatic Port Configuration policy
The automatic Port Configuration (APC) policy is disabled by default. APC provides the ability to
automatically discover port types (host vs. fabric) and dynamically update the routing maps when a
new connection is detected. This policy is intended for a complete hands-off operation. APC
dynamically maps internal ports (F_Ports) to available external ports (N_Ports) so they are evenly
distributed. For example, when a port on the module is connected to a fabric switch, the module
configures the port as an external port. If a host is connected to a port on the FC SAN Module, then
it determines that it is connected and configures the port as an internal port and automatically
maps it to an existing external port with the least number of internal ports mapped to it.
How the APC policy works
When the APC policy is enabled, it applies to all ports on the switch. Enabling the APC policy is
disruptive and erases all existing port mappings. Therefore, before enabling the APC policy, you
must disable the FC SAN Module. When you disable the APC policy, the external port (N_Port)
configuration and the port mapping revert back to the default factory configurations for that
platform. It is recommended that you save the current configuration file using the
configupload
command in case you might need this configuration again.
Enabling and disabling the APC policy
Use the following steps to enable and disable Automatic Port Configuration policy.
Enabling APC policy
1.
Connect to the FC SAN Module and log in using an account assigned to the admin role.
2.
Enter the
switchdisable
command to ensure that the module is disabled.
3.
Enter the
configupload
command to save the module’s current configuration.
4.
Enter the
ag
--
policyenable auto
command to enable the APC policy.
switch:admin>
ag --policyenable auto
All Port related Access Gateway configurations will be lost.
Please save the current configuration using configupload.
Do you want to continue? (yes, y, no, n): [no] y
5.
At the command prompt, type
Y
to enable the policy.
The switch is ready; a reboot is not required.
Disabling APC policy
1.
Connect to the FC SAN Module and log in using an account assigned to the admin role.
2.
Enter the
switchdisable
command to ensure that the module is disabled.
3.
Enter the
configupload
command to save the module’s current configuration.
