Encapsulating Frames

The frame encapsulation feature is disabled by default. If you enable the encapsulation feature, all
outgoing frames are encapsulated.
The switchport encap eisl command only applies to SD port interfaces. If encapsulation is enabled, you
see a new line (
To encapsulate outgoing frames (optional), follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface fc9/32
Step 3
switch(config-if)# switchport mode SD
Step 4
switch(config-if)# switchport encap eisl
switch(config-if)# no switchport encap eisl

SPAN Conversion Behavior

As of Cisco MDS SAN-OS Release 1.1(1), SPAN features (configured in any prior release) are converted
as follows:
•
•
OL-6973-03, Cisco MDS SAN-OS Release 2.x
Encapsulation is eisl
If source interfaces and source VSANs are configured in a given session, then all the source VSANs
are removed from that session.
For example,
Before Cisco MDS SAN-OS Release 1.0(4):
Session 1 (active)
Destination is fc1/9
No session filters configured
Ingress (rx) sources are
vsans 10-11
fc1/3,
Egress (tx) sources are
fc1/3,
Once upgraded to Cisco MDS SAN-OS Release 1.1(1):
Session 1 (active)
Destination is fc1/9
No session filters configured
Ingress (rx) sources are
fc1/3,
Egress (tx) sources are
fc1/3,
Session 1 had both source interfaces and source VSANs before the upgrade. After the upgrade, the
source VSANs were removed (rule 1).
If interface level VSAN filters are configured in source interfaces, then the source interfaces are also
removed from the session. If this interface is configured in both directions, it is removed from both
directions.
For example,
) in the show interface SD_port_interface command output.
Purpose
Enters configuration mode.
Configures the specified interface.
Configures the SD port-mode for interface fc2/1.
Enables the encapsulation option for this SD port.
Disables the encapsulation option and reverts the
switch to factory default.
