Sfp Transmitter Types - Cisco MDS 9000 Series Configuration Manual

SFP Transmitter Types

Step 1
Enter configuration mode:
switch# configure terminal
Step 2 Select a Fibre Channel interface and enter interface configuration submode:
switch(config)# interface fc1/1
Step 3
Prevent the detection of BER events from disabling the interface:
switch(config-if)# switchport ignore bit-errors
(Optional) Prevent the detection of BER events from enabling the interface:
switch(config-if)# no switchport ignore bit-errors
Regardless of the setting of the switchport ignore bit-errors command, a switch generates a syslog message
Tip
when the BER threshold is exceeded.
SFP Transmitter Types
The SFP hardware transmitters are identified by their acronyms when displayed using the show interface
brief command. If the related SFP has a Cisco-assigned extended ID, the show interface and show interface
brief commands display the ID instead of the transmitter type. The show interface transceiver and show
interface fc slot/port transceiver commands display both values (ID and transmitter type) for Cisco-supported
SFPs.
