Performing Advanced Configuration Tasks 2. Enter the appropriate command based on the current state of the port and whether it is necessary to specify a slot number: ∙ To disable a port that is enabled, enter the portDisable command. ∙ To disable a port that is persistently enabled, enter the portCfgPersistentDisable command. In FMS mode, you cannot use the portCfgPersistentDisable command, so you must use the portDisable command instead. ∙ To set a persistently disabled port to normal disabled without enabling the port first, enter the portCfgPersistence --set persistentenable command. In this case, the port becomes normal disabled and not persistently disabled. In FMS mode, you cannot use the portCfgPersistence command. The following example disables port 3 and persistently disables port 4, both in slot 2. switch:admin> portdisable 2/3 switch:admin> portcfgpersistentdisable 2/4 The following example changes port 4 to be normal disabled instead of persistently disabled. switch:admin> portcfgpersistence --set -persistentenable 2/4 Port decommissioning Port decommissioning provides an automated mechanism to remove an E_Port or E_Port trunk port from use. The port decommissioning feature identifies the target port and communicates the intention to decommission the port to those systems within the fabric affected by the action. Each affected system can agree or disagree with the action, and these responses are automatically collected before a port is decommissioned. Fabric OS 7.1.0 and later provides F_Port decommissioning and recommissioning using Brocade Network Advisor 12.1.0 and later. Refer to the Brocade Network Advisor User Manual for details. NOTE All members of a trunk group must have an equal link cost value in order for any of the members to be decommissioned. If any member of a trunk group does not have an equal cost, requests to decommission a trunk member will fail and an error reminding the caller of this requirement is produced. The following restrictions apply to port decommissioning: ∙ The local switch and the remote switch on the other end of the E_Port must both be running Fabric OS 7.0.0 or later. ∙ Port decommissioning is not supported on ports with DWDM, CWDM, or TDM. ∙ Port decommissioning requires that the lossless feature is enabled on both the local switch and the remote switch. Use the portDecom command to begin the decommission process. Setting port speeds Use the following procedure to set port speeds. 1. Connect to the switch and log in using an account with admin permissions. 2. Enter the portCfgSpeed command. The following example sets the speed for port 3 on slot 2 to 16 Gbps: switch:admin> portcfgspeed 2/3 16 Brocade Fabric OS Administration Guide, 8.0.1 53-1004111-02 83
