About 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 encap is set to EISL, all
outgoing frames are transmitted in the EISL frame format, irrespective of the SPAN source(s).
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 (
SD_port_interface command output (see the

About Receive Data Field Size

You can also configure the receive data field size for Fibre Channel interfaces. If the default data field
size is 2112 bytes, the frame length will be 2148 bytes.

Configuring Receive Data Field Size

You can also configure the receive data field size for 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, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface fc1/1
switch(config-if)#
Step 3
switch(config-if)# switchport fcrxbufsize 2000

Purpose
Configures the description of the
interface. The string can be up to 80
characters long.
Clears the description of the interface.

Purpose
Enters configuration mode.
Selects a Fibre Channel interface and enters
interface configuration submode.
Reduces the data field size for the selected
interface to 2000 bytes. The default is 2112
bytes and the range is from 256 to 2112 bytes.
