7 Policy database distribution 1. Log in to the switch using an account with admin permissions, or an account associated with the chassis role and having the OM permissions for the IPfilter RBAC class of commands. 2. Enter the ipFilter --transabort command. IP Filter policy distribution The IP Filter policy is manually distributed by command. The distribution includes both active and defined IP Filter policies. All policies are combined as a single entity to be distributed and cannot be selectively distributed. However, you may choose the time at which to implement the policy for optimization purposes. If a distribution includes an active IP Filter policy, the receiving switches activate the same IP Filter policy automatically. When a switch receives IP Filter policies, all uncommitted changes left in its local transaction buffer are lost, and the transaction is aborted. The IPFilter policy can be manually distributed to the fabric by command; there is no support for automatic distribution. To distribute the IPFilter policy, see "Distributing the local ACL policies" on page 227 for instructions. Switches with Fabric OS v6.2.0 or later have the ability to accept or deny IP Filter policy distribution, through the commands fddCfg --localaccept or fddCfg --localreject. See "Policy database distribution" on page 224 for more information on distributing the IP Filter policy. Virtual Fabrics considerations: To distribute the IPFilter policy in a logical fabric, use the chassisDistribute command. Managing filter thresholds Fabric OS v7.1.0 allows you to configure filter thresholds using the fmMonitor command. 1. Connect to the switch and log in using an account with admin permissions, or an account with OM permissions for the FabricWatch RBAC class of commands. 2. Enter the fmMonitor command. Example of fmMonitor command: admin> fmMonitor --create ex1 -pat 12,0xFF,0x08 -port 2/1-2,8/3 -highth 1000 - action snmp,raslog -timebase minute Policy database distribution Fabric OS lets you manage and enforce the ACL policy database on either a per-switch or fabric-wide basis. The local switch distribution setting and the fabric-wide consistency policy affect the switch ACL policy database and related distribution behavior. The ACL policy database is managed as follows: • Switch database distribution setting - Controls whether or not the switch accepts or rejects databases distributed from other switches in the fabric. The distribute command sends the database from one switch to another, overwriting the target switch database with the distributed one. To send or receive a database the setting must be accept. For configuration instructions, see "Database distribution settings" on page 225. Virtual Fabric considerations: FCS, DCC, SCC, and AUTH databases can be distributed using the -distribute command, but the PWD and IPFILTER databases are blocked from distribution. 224 Fabric OS Administrator's Guide 53-1002745-02
