Introduction
This document provides information about troubleshooting common software and hardware
problems with HPE FlexNetwork 5130 EI switches.
This document is not restricted to specific software or hardware versions.
General guidelines
IMPORTANT:
To prevent a problem from causing loss of configuration, save the configuration each time you finish
configuring a feature. For configuration recovery, regularly back up the configuration to a remote
server.
When you troubleshoot HPE FlexNetwork 5130 EI switches, follow these general guidelines:
•To help identify the cause of the problem, collect system and configuration information,
including:
{Symptom, time of failure, and configuration.
{Network topology information, including the network diagram, port connections, and points
of failure.
{Log messages and diagnostic information. For more information about collecting this
information, see "Collecting log and operating information."
{Photos of the hardware.
{Steps you have taken, such as reconfiguration, cable swapping, and reboot.
{Output from the commands executed during the troubleshooting process.
•To ensure safety, wear an ESD-preventive wrist strap when you replace or maintain a hardware
component.
Collecting log and operating information
IMPORTANT:
By default, the information center is enabled. If the feature is disabled, you must use the info-cente
r
enable command to enable the feature for collecting log messages.
Table 1 shows the types of files that the system uses to store operating log and status information.
You can export these files by using FTP or TFTP.
In an IRF system, these files are stored on the master device. Multiple devices will have log files if
master/subordinate switchovers have occurred. You must collect log files from all these devices. To
more easily locate log information, use a consistent rule to categorize and name files. For example,
save log files to a separate folder for each member device, and include their slot numbers in the
folder names.
Table 1 Log and operating information
Category File name format Content
Common log logfile.log Command execution and operational log messages.

2
Category File name format Content
Diagnostic log diagfile.log
Diagnostic log messages about device operation, including the
following items:
•Parameter settings used when an error occurs.
•Information about a card startup error.
•Handshaking information between member devices when
a communication error occurs.
Operating
statistics file-basename.gz
Current operation statistics for feature modules, including the
following items:
•Device status.
•CPU status.
•Memory status.
•Configuration status.
•Software entries.
•Hardware entries.
Collecting common log messages
1. Save the common log messages from the log buffer to a log file.
By default, the log file is saved in the logfile directory of the Flash memory on each member
device.
<Sysname> logfile save
The contents in the log file buffer have been saved to the file
flash:/logfile/logfile.log
2. Identify the log file on each member device:
# Display the log file on the master device.
<Sysname> dir flash:/logfile/
Directory of flash:/logfile
0 -rw- 21863 Jul 11 2013 16:00:37 logfile.log

# Display the log file on each subordinate device:
<Sysname> dir slot2#flash:/logfile/
Directory of slot2#flash:/logfile
0 -rw- 21863 Jul 11 2013 16:00:37 logfile.log
524288 KB total (36944 KB free)
3. Transfer the files to the desired destination by using FTP or TFTP. (Details not shown.)
Collecting diagnostic log messages
1. Save the diagnostic log messages from the diagnostic log file buffer to a diagnostic log file.
By default, the diagnostic log file is saved in the diagfile directory of the Flash memory on each
member device.
<Sysname> diagnostic-logfile save
The contents in the diagnostic log file buffer have been saved to the file
flash:/diagfile/diagfile.log
2. Identify the diagnostic log file on each member device:

3
# Display the diagnostic log file on the master device.
<Sysname> dir flash:/diagfile/
Directory of flash:/diagfile
0 -rw- 161321 Jul 11 2013 16:16:00 diagfile.log

524288 KB total (36944 KB free)
3. Transfer the files to the desired destination by using FTP or TFTP. (Details not shown.)
Collecting operating statistics
You can collect operating statistics by saving the statistics to a file or displaying the statistics on the
screen.
When you collect operating statistics, follow these guidelines:
•Log in to the device through a network port instead of the console port if any network ports are
available. Network ports are faster than the console port.
•Do not execute commands during operating statistics collection.
•As a best practice, save operating statistics to a file to ensure that the information is retained.
NOTE:
The amount of time to collect statistics increases along with the number of IRF member devices.
To collect operating statistics:
1. Disable pausing between screens of output if you want to display operating statistics on the
screen. Skip this step if you are saving statistics to a file.
<Sysname> screen-length disable
2. Collect operating statistics for multiple feature modules.

Solution
Choose a solution depending on the module that uses the ACL.
ACL used in a QoS policy
To resolve the problem when theACL is used in a QoS policy:
1. Verify that the QoS policy is configured correctly:
a. Use one of the following commands to check the QoS policy for configuration errors,
depending on the policy application destination:
Destination Command
Interface display qos policy interface
VLAN display qos vlan-policy
Global display qos policy global
Control plane display qos policy control-plane slot
slot-number
b. If the QoS policy does not contain a class-behavior association, associate the traffic
behavior with the traffic class.
c. If the QoS policy contains a class-behavior association, execute the display traffic
classifier user-defined command and the display traffic behavior user-defined
command to check for traffic class and behavior configuration errors, respectively.
−If they are configured incorrectly, reconfigure them.
−If they are configured correctly, go to step 2.
2. Verify that the ACL is configured correctly.
Execute the display acl command to check whether the ACL is configured correctly.
{If the ACL is configured incorrectly, reconfigure it.

Troubleshooting IRF
This section provides troubleshooting information for common problems with IRF.
IRF fabric establishment failure
Symptom
An IRF fabric cannot be established.
Troubleshooting flowchart
Figure 3 Troubleshooting an IRF fabric establishment failure

13
Solution
To resolve the problem:
1. Verify that the number of member devices does not exceed the upper limit (varies by software
version).
If you are adding a new member device to an existing IRF fabric or merging IRF fabrics, use the
display irf command to identify the number of member devices in the IRF fabrics. If the total
number of member devices exceeds the upper limit, the IRF setup will fail.
2. Verify that the member ID of each member device is unique:
a. Execute the display irf command to view the member ID of each member device.
b. Assign a unique member ID to each member.
−If you are adding a new member device to an existing IRF fabric, assign the member
device a member ID that is not being used in the IRF fabric.
−If you are merging IRF fabrics, make sure each member device in these IRF fabrics has
a unique member ID.
3. Verify that the IRF port bindings and physical IRF link connections are correct:
IMPORTANT:
When you connect two neighboring IRF members, you must connect the physical ports of
IRF-port 1 on one member to the physical ports of IRF-port 2 on the other.
a. Execute the display irf configuration command on each member device, and check the
IRF-Port1 and IRF-Port2 fields for IRF port bindings.
b. Verify that the physical IRF connections are consistent with the IRF port bindings.
c. If there are binding errors or connection inconsistencies, reconfigure the IRF port bindings
or reconnect the physical IRF ports.
4. Verify that the IRF links are 10 Gbps.
a. Verify that the transceiver modules or cables for IRF connection are labeled with 10Gbps or
SFP+.
b. Replace a transceiver module or cable if it is not for 10-Gbps connection.
5. (Optional.) Verify that transceiver modules at the two ends of an IRF link are the same type.
If the transceiver modules are not the same type, replace them to be the same type.
Skip this step if you are using SFP+ cables to connect IRF member devices.
6. Verify that all IRF links are up:
a. Execute the display irf topology command, and then check the Link field.
−If the Link field for each IRF port does not display DOWN, go to step 7.
−If
the Link field for an IRF port displays DOWN, go to step b.
b. Execute the display irf link command, and then check the Status field of the physical ports
bound to the IRF port.
−If the field displays DOWN or ADM (administratively down) for all the physical ports,
remove the link failures or use the undo shutdown command to bring up the
administratively down ports.
−If the field displays UP for a minimum of one of the physical ports, go to step c.
c. Save the configuration, and then execute the irf-port-configuration active command in
system view to activate the IRF port configuration.
IMPORTANT:
Activating IRF port configuration requires a reboot. To prevent configuration loss, you must

14
save the configuration before you execute the irf-port-configuration active command.
7. Verify that all member devices use the same software version:
a. Execute the display version command to identify the software version of each member
device.
b. Upgrade the software of all member devices to the same version.
NOTE:
Typically, the irf auto-update enable command can automatically synchronize a member
device with the software version of the master device. However, the synchronization might fail
when the gap between the software versions is too large. For more information, see the release
notes.
8. If the problem persists, contact Hewlett Packard Enterprise Support.
Related commands

Solution
To resolve the problem:
1. Verify that all physical connections are correct.
You can verify the physical connections against your network plan.
2. Verify that all member ports are up:
a. Execute the display interface command to display the status of the member ports.
b. If the member ports are down, follow the solution in "Troubleshooting ports" to troubleshoot
the problem.
3. Verify that the member ports have the same operational key and attribute configurations as the
reference port:
Are all physical connections correct?
Are all member ports up?
Connect physical links correctly
Bring all member ports up
No
Yes
No
Yes
Operational key/attributes same as the
reference port?
Set operational key/attributes
same as the reference port
No
Yes
Set the number of member ports
less than or equal to upper limit on
Selected ports
Yes
No
More member ports than upper limit on
Selected ports?
Operational key/attributes of the peers same as
the peer of the reference port?
Set operational key/attributes of
the peers same as the peer of
the reference port
No

a. Execute the display link-aggregation verbose command to display the Selected state of
the member ports.
b. Execute the display current-configuration interface command to display the
configurations of the aggregate interface and the Unselected ports.
c. Configure the Unselected ports to make sure they have the same operational key and
attribute configurations as the reference port.
4. Identify the aggregation mode of the aggregation group.
{If the aggregation mode is static, proceed to step 6.
{If the aggregation mode is dynamic, proceed to step 5.
5. Verify that the peer member ports have the same operational key and attribute configurations
as the peer port of the reference port:
a. Execute the display current-configuration interface command on the peer device to
display the configurations of the peer member ports.
b. Configure the peer member ports to make sure the peer ports have the same operational
key and attribute configurations as the peer port of the reference port.
6. Verify that the number of member ports in the aggregation group does not exceed the
configured maximum number of Selected ports.
a. Execute the link-aggregation selected-port maximum command to set the maximum
number of Selected ports allowed in the aggregation group. The value range is 1 to 16.
b. Execute the display link-aggregation verbose command to verify that the number of
member ports does not exceed the configured maximum number of Selected ports.
If the number of member ports exceeds the maximum number of Selected ports, the ports
with higher port numbers are in Unselected state.
c. Use the undo port link-aggregation group command to remove undesired member ports
from the aggregation group.
This makes sure all member ports you assign to the aggregation group can become
Selected ports.
