7 SCC Policies Table 34 shows the behavior of a DCC policy created manually with the physical PWWN of a device. The configurations shown in this table are the recommended configurations when an FA-PWWN is logged into the switch. TABLE 34 DCC policy behavior when created manually with PWWN Configuration WWN seen on Behavior when DCC policy DCC policy list activates Behavior on portDisable and portEnable • FA-PWWN has logged into the switch. PWWN • DCC policy creation manually with physical PWWN of device. • DCC policy activation. Traffic will not be disrupted. • DCC policy creation. manually with PWWN physical PWWN • FA-PWWN has logged into the switch. • DCC policy activation.

Ports will come up without security issues. Ports will come up without security issues. Ports will come up without any security issues. SCC Policies The switch connection control (SCC) policy is used to restrict which switches can join the fabric. Switches are checked against the policy each time an E_Port-to-E_Port connection is made. The policy is named SCC_POLICY and accepts members listed as WWNs, domain IDs, or switch names. Only one SCC policy can be created. By default, any switch is allowed to join the fabric; the SCC policy does not exist until it is created. When connecting a Fibre Channel router to a fabric or switch that has an active SCC policy, the front domain of the Fibre Channel router must be included in the SCC policy. SCC policy states are shown in Table 35. TABLE 35 SCC policy states Policy state SCC policy enforcement No active policy Active policy that has no members Active policy that has members All switches can connect to the switch with the specified policy. All neighboring switches are segmented. The neighboring switches not specified in the SCC policy are segmented. Virtual Fabrics considerations: In a logical fabric environment the SCC policy enforcement is not done on the logical ISL. For a logical ISL-based switch, the SCC policy enforcement is considered as the reference and the logical ISL is formed if the SCC enforcement passes on the extended ISL. The following changes: • A logical switch supports an SCC policy. You can configure and distribute an SCC policy on a logical switch. • SCC enforcement is performed on a ISL based on the SCC policy present on the logical switch. For more information on Virtual Fabrics, refer to Chapter 10, "Managing Virtual Fabrics". 206 Fabric OS Administrator's Guide 53-1002745-02
