Problem
Potential Problem Area
Potential Fix
Basic Connectivity Between CNA and
MXL Series switch is not present (ping
between devices)
Cable is not connected or is failing
Connect or Change cable and
reconnect
The OS on the server is not
configured to have the network card
enabled or active
Check adapter settings in the OS and
verify ports turned on or enabled
The driver for the applicable OS is
not loaded
Load driver and ensure both Ethernet
and storage device drivers are in
place for CNA (if applicable)
Internal server facing ports on the
MXL may not be enabled (no
shutdown)
Determine which internal ports
should be enabled and configure the
ports on with the "no shutdown"
command
External or regular ports on the MXL
switch or Cisco Nexus 5000 series
switch may not be enabled (no
shutdown)
Determine which external ports
should be enabled and configure the
ports on with the "no shutdown"
command
Untagged, Native VLAN's, or switch
default vlan-id may not be
configured appropriately.
Configure the switch default vlan-id
and this should be the VLAN used as
default or native for the FCoE ports.
The initial FIP negotiations will occur
on this VLAN. See MXL CLI section or
Cisco Nexus 5000 series CLI section
for detail on this.
ENode's or FCF entries are not present
on the Force10 MXL switch
See above basic connectivity
problems
see above
Applicable FCoE or storage driver is
not configured in the server OS for
the CNA
This could be an indication that the
storage side of the CNA driver has not
been fully installed.
CNA may not be configured as willing
(will negotiate values with the FCF
switch)
Some CNA's have the option to
configure the DCB settings manually.
This will potentially cause
misbehavior due to the DCBX
negotiations not occurring as
expected.
-
Cisco Nexus 5000 series switch may
not have the supported firmware in
place. Must be 5.0(2)N1(1) or
greater
Download and install latest Cisco
firmware.
Feature FCoE may not be configured
on Cisco Nexus 5000 series switch
Ensure FCoE feature is configured on
Nexus 5000 Series switch
fip-snooping may not be enabled on
the FCoE VLAN on the Dell Force10
MXL
See Dell Force10 MXL CLI section for
explanation of enabling VLAN for fip-
snooping
The VFC entries may not be present
on the Cisco Nexus 5000 series
switch
Ensure that VFC's are created that
will be applicable to the connection.
This can be bound to the FCoE-FIP
MAC of the CNA or to the physical
interface of the Cisco Nexus 5000
Series switch
