configure 2 The user-defined value is in the range from 80 through 500 milliseconds and this value can be incremented with resolution of 1. In a logical switch, the edge hold time configuration is updated only for Condor3 ports. If Condor2 ports are present in the logical switch, the SWCH-1025 RASLog message is triggered to indicate that Condor2 ports are present and the edge hold time configuration will not change for these ports. Virtual Channel Settings VC Priority specifies the class of frame traffic given priority for a virtual channel. The switch enables fine-tuning for a specific application by configuring the parameters for eight virtual channels. The first two virtual channels are reserved for switch internal functions and are not available for modification. The default virtual channel settings have already been optimized for switch performance. Changing the default values can improve switch performance but can also degrade performance. Do not change these settings without fully understanding the effects of the changes. The values for virtual channel settings are as follows: Field Default Range VC Priority 2 2 2 to 3 VC Priority 3 2 2 to 3 VC Priority 4 2 2 to 3 VC Priority 5 2 2 to 3 VC Priority 6 3 2 to 3 VC Priority 7 3 2 to 3 F_Port Login Parameters Specifies the F_Port login parameters. The following F_Port login settings are configurable. Unless there are issues with F_Port staging, do not change default values. (* = multiplication symbol) Field Type Default Range Maximum logins Number For directors: 1 to per switch 16 * the max number 126 * the max of physical ports Logins per second Number 0 0 to 100 Login stage interval (milli-seconds) Number 0 0 to 10000 Stage FDISC logins with busy rejects: Number 0 1 to 255 Enforce FLOGI/FDISC login: Number 0 0 to 1 Maximum logins per switch Sets a switch-wide limit on allowed logins. The maximum login per switch has decreased with Fabric OS v6.4.0. When upgrading from pre-v6.4.0 firmware versions, the configured maximum is carried forward and may exceed the v6.4.0 limit. It is recommended to reconfigure this parameter to be within the range permitted in Fabric OS v6.4.0. The following three parameters are related to staged F_Port logins by FLOGI requests and virtual device logins by FDISC(SID==0) requests. Logins per second Specifies the number of logins the switch accepts per second in staged F_Port bring up. Login stage interval Specifies the stage interval in staged F_Port bring up.
