Access Gateway policy enforcement matrix
shows which policies can be enabled at the same time. For example, in the Auto Port
Configuration policy row, only N_Port Trunking and Advanced Device Security can be enabled with
this policy.
Advanced Device Security policy
Advanced Device Security (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 the ADS 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 F_Ports on Core AGs, such as the AGs that are directly
connected to fabric. Use the agshow
--
name command on the fabric switch to display the F_Ports
of both the Core and Edge AGs.
Alternatively, the security policy can be established in the Enterprise fabric using the Device
Connection Control (DCC) policy. For information on configuring the DCC policy, see
on page 60. 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 the Failover and Failback policies are enabled.
