Configuring SD Port Frame Encapsulation
The switchport encap eisl command only applies to SD port interfaces. This command determines the frame
format for all frames transmitted by the interface in SD port mode. If the encapsulation is set to EISL, all
outgoing frames are transmitted in the EISL frame format, for all SPAN sources.
The switchport encap eisl command is disabled by default. If you enable encapsulation, all outgoing frames
are encapsulated, and you will see a new line (Encapsulation is eisl) in the show interface SD_port_interface
command output.
Configuring Receive Data Field Size
You can configure the receive data field size for native Fibre Channel interfaces (but not for virtual Fibre
Channel interfaces). If the default data field size is 2112 bytes, the frame length will be 2148 bytes.
To configure the receive data field size, perform this task:
SUMMARY STEPS
1. switch# configuration terminal
2. switch(config)# interface fc slot/port
3. switch(config-if)# switchport fcrxbufsize 2000
OL-27583-01
Purpose
Enters configuration mode.
Selects the specified interface and enters interface
configuration mode.
Note
Reverts to the factory default (auto) administrative speed of
the interface.
