Fibre Channel Interfaces Chapter 13 Configuring Interfaces Send documentation comments to [email protected] • Momentary sync loss. • Loose cable connection at one or both ends. • Improper GBIC or SFP connection at one or both ends. A bit error rate threshold is detected when 15 error bursts occur in a 5-minute period. By default, the switch disables the interface when the threshold is reached. You can issue a shutdown and no shutdown command sequence to reenable the interface. You can configure the switch to not disable an interface when the threshold is crossed. By default, the threshold disables the interface. To disable the bit error threshold for an interface, follow these steps: Step 1 Step 2 Step 3 Command switch# config t switch(config)# interface fc1/1 switch(config-if)# switch(config-if)# switchport ignore bit-errors switch(config-if)# no switchport ignore bit-errors Purpose Enters configuration mode. Selects a Fibre Channel interface and enters interface configuration submode. Prevents the detection of bit error threshold events from disabling the interface. Prevents the detection of bit error threshold events from enabling the interface. Note Regardless of the setting of the switchport ignore bit-errors command, the switch generates a syslog message when bit error threshold events are detected. Switch Port Attribute Default Values You can configure attribute default values for various switch port attributes. These attributes will be applied globally to all future switch port configurations, even if you do not individually specify them at that time. To configure switch port attributes, follow these steps: Step 1 Command switch# config t Purpose Enters configuration mode. 13-20 Cisco MDS 9000 Family CLI Configuration Guide OL-18084-01, Cisco MDS NX-OS Release 4.x
