Configuring Security Policies TABLE 39 FCS policy states (continued) Policy state Active policy with multiple entries Characteristics A Primary FCS switch and one or more backup FCS switches are designated. If the Primary FCS switch becomes unavailable, the next switch in the list becomes the Primary FCS switch. FCS policy restrictions The backup FCS switches normally cannot modify the policy. However, if the Primary FCS switch in the policy list is not reachable, then a backup FCS switch is allowed to modify the policy. Once an FCS policy is configured and distributed across the fabric, only the Primary FCS switch can perform certain operations. Operations that affect fabric-wide configuration are allowed only from the Primary FCS switch. Backup and non-FCS switches cannot perform security, zoning and AD operations that affect the fabric configuration. The following error message is returned if a backup or non-FCS switch tries to perform these operations: Can only execute this command on the Primary FCS switch. Operations that do not affect the fabric configuration, such as show or local switch commands, are allowed on backup and non-FCS switches. FCS enforcement applies only for user-initiated fabric-wide operations. Internal fabric data propagation because of a fabric merge is not blocked. Consequently, a new switch that joins the FCS-enabled fabric could still propagate the AD and zone database. Table 40 shows the commands for switch operations for Primary FCS enforcement. TABLE 40 FCS switch operations Allowed on FCS switches secPolicyAdd (Allowed on all switches for SCC and DCC policies as long as it is not fabric-wide) secPolicyCreate (Allowed on all switches for SCC and DCC policies as long as it is not fabric-wide) secPolicyDelete (Allowed on all switches for SCC and DCC policies as long as its not fabric-wide) secPolicyRemove (Allowed on all switches for SCC and DCC policies as long as its not fabric-wide) fddCfg -- fabwideset Any fabric-wide commands All zoning commands except the show commands All AD commands Allowed on all switches secPolicyShow fddCfg --localaccept or fddCfg --localreject userconfig, Passwd, Passwdcfg (Fabric-wide distribution is not allowed from a backup or non-FCS switch.) secPolicyActivate secPolicySave secPolicyAbort SNMP commands configupload Any local-switch commands In Fabric OS v7.1.0 and later, to avoid segmentation of ports due to a member-list order mismatch, security policy members are sorted based on WWN. By default, DCC and SCC policy members are sorted based on WWN. Switches running earlier Fabric OS versions will have the member list in the unsorted manner. Any older-version switch with a policy already created in unsorted order will have port segmentation due to order mismatch when attempting to join any switch with Fabric OS v7.1.0 or later. To overcome the order mismatch, you can modify the member list in the switch by using the -legacy option in the secPolicyAdd and secPolicyCreate commands.
