Configuring SAN Port Channels
SAN port channels are created with default values. You can change the default configuration just as any other
physical interface.
If the following requirements are not met, a SAN port channel error is detected:
•
Each switch on either side of a SAN port channel must be connected to the same number of interfaces.
•
Each interface must be connected to a corresponding interface on the other side.
•
Links in a SAN port channel cannot be changed after the port channel is configured. If you change the
links after the port channel is configured, be sure to reconnect the links to interfaces within the port
channel and reenable the links.
If all three conditions are not met, the faulty link is disabled. Enter the show interface command for that
interface to verify that the SAN port channel is functioning as required.
Note
SAN Port Channel Guidelines and Limitations
•
The number of SAN port channels and virtual FC port channels, together, can be only 8 on the Cisco
Nexus 9000 Series switch.
•
The maximum number of FC interfaces that can be combined into a SAN port channel is limited to 16.
•
The default channel mode on Cisco Nexus 9000 Series switches for SAN port channels is active; this
cannot be changed.
Creating a SAN Port Channel
This section explains how to create a SAN port channel.
Procedure
Step 1
switch# configuration terminal
Enters the global configuration mode.
Step 2
switch(config)# interface san-port-channel channel-number
Creates the specified SAN port channel using the default mode (on). The SAN port channel number is in the
range of 1 to 256
The following example shows the SAN port channel creation:
switch(config)# interface san-port-channel 1
switch(config-if)#
