Access Gateway policy enforcement matrix
The following table shows which combinations of policies can co-exist with each other.
Advanced Device Security policy
ADS is a security policy that restricts access to the fabric at the AG level to a set of authorized
devices. Unauthorized access is rejected and the system logs a RASLOG message. You can
configure the list of allowed devices for each F_Port by specifying their Port WWN (PWWN). The ADS
policy secures virtual and physical connections to the SAN.
How the ADS policy works
When you enable this policy, it applies to all F_Ports on the AG-enabled module. By default, all
devices have access to the fabric on all ports. You can restrict the fabric connectivity to a particular
set of devices where AG maintains a per-port allow list for the set of devices whose PWWN you
define to log in through an F_Port. You can view the devices with active connections to an F_Port
using the ag --show command.
NOTE
The ag
--
show command only displays the Core AGs, such as the AGs that are directly connected to
fabric. The agshow
--
name name command displays the F_Ports of both the Core and Edge AGs.
Alternatively, the security policy can be established in the Enterprise fabric using the DCC policy.
For information on configuring the DCC policy, see
“Enabling the DCC policy on trunk” on page 53.
The DCC policy in the Enterprise fabric takes precedence over the ADS policy. It is generally
recommended to implement the security policy in the AG module rather than in the main fabric,
especially if Failover and Failback policies are enabled.
