Supported Releases 10.4.0E(R3) or later re-balance fc npg sessions vfabric Re-balances the FC sessions across FC uplinks. Syntax Parameters Defaults Command Mode Usage Information re-balance fc npg sessions vfabric vfabric-id [dry-run][brief] None Not configured EXEC Triggers the load-balancing mechanism to redistribute the sessions across the FC uplinks. The dry-run option displays the current state of the system, sessions that are cleared, and the system state after the load balancing is done without actually doing it. You can use the brief option (both in dry run and actual run) to view only the session redistribution information. You can configure fcoe delay fcf-adv timer that is based on the switch configuration to balance the system during reload. Even if the system is unbalanced after reload, you can use this command in the switch to balance the sessions, within the uplinks. This command is supported in the NPG mode. Re-balance is not recommended for a NPG cascading topology. The fields and their corresponding descriptions displayed in this command are as follows: ● Uplink Intf-The name of the FC uplink interface. ● FLOGI-Number of Fabric Login Sessions in the FC uplink interface. ● FDISC-Number of Fabric Discovery Sessions in the FC uplink interface. ● Load-Total number of sessions (FLOGI and FDISC) in the FC uplink interface. ● Speed-Link speed of the FC uplink interface. ● Excess Load-Excess load is the absolute (Current load on the link - ((Minimum load per 8G speed in current state) * port-speed/8G)). It captures the level to which the corresponding link is oversubscribed when compared to other FC upstream links in the system. ● Node WWPN-World-Wide Port Name is used for the Fabric Login Request of the Server that is connected to the OS10 switch. It can be an FCoE server or an FC server. ● From Uplink Intf-Interface name of the FC uplink from which the sessions from the server are redistributed. ● To Uplink Intf-Interface name of the FC uplink to which the sessions are mapped when the server logins. ● No. of sessions-Count of redistributed sessions.
