Recovering a Lost Password

This section describes how to recover a lost network administrator password using the console port of the switch.

You can recover the network administrator password using one of two methods:

From the CLI with a username that has network-admin privileges

By power cycling the switch

This section includes the following topics:

Using the CLI with Network-Admin Privileges, page 50-2

Power Cycling the Switch, page 50-2

Using the CLI with Network-Admin Privileges

If you are logged in to, or can log into, the switch with a username that has network-admin privileges, follow these steps:


Step 1 Verify that your username has network-admin privileges.

switch# show user-account
user:admin
        this user account has no expiry date
        roles:network-admin
 
   
user:dbgusr
        this user account has no expiry date
        roles:network-admin network-operator
 
   

Step 2 Assign a new network administrator password if your username has network-admin privileges.

switch# configure terminal
switch(config)# username admin password <new password>
switch(config)# exit
switch#
 
   

Step 3 Save the configuration.

switch# copy running-config startup-config
 
   

Power Cycling the Switch

If you cannot start a session on the switch that has network-admin privileges, you must recover the network administrator password by power cycling the switch.


Caution This procedure disrupts all traffic on the switch.


Note You cannot recover the administrator password from a Telnet or SSH session. You must have access to the local console connection.


To recover the network administrator password by power cycling the switch, follow these steps:


Step 1 Establish a terminal session on the console port of the supervisor module.

Step 2 Power cycle the switch.

Step 3 Press the Ctrl-B key sequence from the console port session when the switch begins the Cisco NX-OS software boot sequence to enter the boot prompt mode.

Ctrl-B 
switch(boot)#
 
   

Step 4 Reset the network administrator password.

switch(boot)# configure terminal
switch(boot-config)# admin-password <new password>
switch(boot-config)# exit
switch(boot)#
 
   

Step 5 Display the bootflash: contents to locate the Cisco NX-OS software image file.

switch(boot)# dir bootflash:
 
   

Step 6 Load the Cisco NX-OS system software image.

In the following example, the system image filename is nx-os.bin:

switch(boot) # load bootflash:nx-os.bin
 
   

Step 7 Log in to the switch using the new administrator password.

switch login: admin
Password: <new password>
 
   

Step 8 Reset the new password to ensure that is it is also the SNMP password.

switch# configure terminal
switch(config)# username admin password <new password>
switch(config)# exit
switch#
 
   

Step 9 Save the configuration.

switch# copy running-config startup-config
 
   

Using Ethanalyzer

Ethanalyzer is a Cisco NX-OS protocol analyzer tool based on the Wireshark (formerly Ethereal) open source code. Ethanalyzer is a command-line version of Wireshark that captures and decodes packets. You can use Ethanalyzer to troubleshoot your network and analyze the control-plane traffic.

To configure Ethanalyzer, use the following commands:

Command
Purpose

ethanalyzer local interface interface

Captures packets sent or received by the supervisor and provides detailed protocol information.

For the following commands, interface is inbound-hi (Inbound high priority interface), inbound-low (Inbound low priority interface), or mgmt (management interface).

ethanalyzer local interface interface brief

Captures packets sent or received by the supervisor and provides a summary of precool information.

ethanalyzer local interface interface limit-captured-frames

Limits the number of frames to capture.

ethanalyzer local interface interface limit-frame-size

Limits the length of the frame to capture.

ethanalyzer local interface interface capture-filter

Filters the types of packets to capture.

ethanalyzer local interface interface display-filter

Filters the types of captured packets to display.

ethanalyzer local interface interface write

Saves the captured data to a file.

ethanalyzer local read file

Opens a captured data file and analyzes it.


Ethanalyzer does not capture data traffic that Cisco NX-OS forwards in the hardware.

Ethanalyzer uses the same capture filter syntax as tcpdump. For more information, see the following URL:

http://www.tcpdump.org/tcpdump_man.html

For information on the syntax of the display filter, see the following URL:

http://wiki.wireshark.org/DisplayFilters

This example shows captured data (limited to four packets) on the management interface:

switch# ethanalyzer local interface mgmt brief limit-captured-frames 4

Troubleshooting Fibre Channel

This section describes troubleshooting methods to resolve issues with Fibre Channel. This section includes the following topics:

fctrace, page 50-5

fcping, page 50-7

fctrace

The fctrace feature provides the following capabilities:

Trace the route followed by data traffic.

Compute inter-switch (hop-to-hop) latency.

You can invoke fctrace by providing the FC ID, the N port WWN, or the device alias of the destination.

The trace frame is routed normally through the network until it reaches the far edge of the fabric. When the frame reaches the edge of the fabric (the F port connected to the end node with the given port WWN or the FC ID), the frame is looped back (swapping the source ID and the destination ID) to the originator.

If the destination cannot be reached, the path discovery starts, which traces the path up to the point of failure.


Note The fctrace feature works only on TE ports. Make sure that only TE ports exist in the path to the destination. If there is an E port in the path, the fctrace frame is dropped by that switch. Also, fctrace times out in the originator, and path discovery does not start.


To perform the fctrace operation, perform one of these tasks:

Command
Purpose

switch# fctrace fcid 0xd70000 vsan 1

Route present for :  0xd70000

20:00:00:0b:46:00:02:82(0xfffcd5)

Timestamp Invalid.

20:00:00:05:30:00:18:db(0xfffcd7)

Timestamp Invalid.

20:00:00:05:30:00:18:db(0xfffcd7)

Invokes fctrace for the specified FC ID of the destination N port.

switch# fctrace pwwn 21:00:00:e0:8b:06:d9:1d vsan 1 timeout 5

Route present for : 21:00:00:e0:8b:06:d9:1d

20:00:00:0b:46:00:02:82(0xfffcd5)

Timestamp Invalid.

20:00:00:05:30:00:18:db(0xfffcd7)

Timestamp Invalid.

20:00:00:05:30:00:18:db(0xfffcd7)

Invokes fctrace using the pWWN of the destination N port.

By default the period to wait before timing out is 5 seconds, The range is from one through 10 seconds.

switch# fctrace device-alias disk1 v 1

Route present for : 22:00:00:0c:50:02:ce:f8

20:00:00:05:30:00:31:1e(0xfffca9)

Invokes fctrace using the device alias of the destination N port.


fcping

The fcping feature verifies reachability of a node by checking its end-to-end connectivity. You can invoke the fcping feature by providing the FC ID, the destination port WWN, or the device alias information.

To perform a fcping operation, perform this task:

 
Command
Purpose

Step 1 

switch# fcping fcid 0xd70000 vsan 1

28 bytes from  0xd70000  time = 730 usec

28 bytes from  0xd70000  time = 165 usec

28 bytes from  0xd70000  time = 262 usec

28 bytes from  0xd70000  time = 219 usec

28 bytes from  0xd70000  time = 228 usec

5 frames sent, 5 frames received, 0 timeouts

Round-trip min/avg/max = 165/270/730 usec

Invokes fcping for the specified pWWN or the FC ID of the destination. By default, five frames are sent.

switch# fcping fcid 0xd70000 vsan 1 count 10

28 bytes from  0xd70000  time = 730 usec

28 bytes from  0xd70000  time = 165 usec

28 bytes from  0xd70000  time = 262 usec

28 bytes from  0xd70000  time = 219 usec

28 bytes from  0xd70000  time = 228 usec

28 bytes from  0xd70000  time = 230 usec

28 bytes from  0xd70000  time = 230 usec

28 bytes from  0xd70000  time = 225 usec

28 bytes from  0xd70000  time = 229 usec

28 bytes from  0xd70000  time = 183 usec

10 frames sent, 10 frames received, 0 timeouts

Round-trip min/avg/max = 165/270/730 usec

Sets the number of frames to be sent using the count option. The range is from 0 through 2147483647. A value of 0 causes the command to send frames forever.

switch# fcping fcid 0xd500b4 vsan 1 timeout 10

28 bytes from  0xd500b4  time = 1345 usec

...

5 frames sent, 5 frames received, 0 timeouts

Round-trip min/avg/max = 340/581/1345 usec

Sets the timeout value. The default period to wait is 5 seconds. The range is from 1 through 10 seconds.

switch# fcping device-alias disk1 vsan 1

28 bytes from 22:00:00:0c:50:02:ce:f8 time = 1883 usec

28 bytes from 22:00:00:0c:50:02:ce:f8 time = 493 usec

28 bytes from 22:00:00:0c:50:02:ce:f8 time = 277 usec

28 bytes from 22:00:00:0c:50:02:ce:f8 time = 391 usec

28 bytes from 22:00:00:0c:50:02:ce:f8 time = 319 usec

5 frames sent, 5 frames received, 0 timeouts

Round-trip min/avg/max = 277/672/1883 usec

Invokes fcping for the specified device alias of the destination.

Step 2 

switch# fcping fcid 0x010203 vsan 1

No response from the N port.

switch# fcping pwwn 21:00:00:20:37:6f:db:dd vsan 1

28 bytes from 21:00:00:20:37:6f:db:dd time = 1454 usec

...

5 frames sent, 5 frames received, 0 timeouts

Round-trip min/avg/max = 364/784/1454 usec

Returns a "No response from the N port" message even when the N port is active. This is due to resource exhaustion at the N port.

Retry the command a few seconds later.

Verifying Switch Connectivity

You can verify connectivity to a destination switch.


Note The FC ID variable used in this procedure is the domain controller address; it is not a duplication of the domain ID.


To verify connectivity to a destination switch, perform this task:

 
Command
Purpose

Step 1 

switch# show fcdomain domain-list vsan 200

Number of domains: 7

Domain ID              WWN

---------    -----------------------

  0x01(1)    20:c8:00:05:30:00:59:df [Principal]

  0x02(2)    20:c8:00:0b:5f:d5:9f:c1

0x6f(111)    20:c8:00:05:30:00:60:df

0xda(218)    20:c8:00:05:30:00:87:9f [Local]

  0x06(6)    20:c8:00:0b:46:79:f2:41

  0x04(4)    20:c8:00:05:30:00:86:5f

0x6a(106)    20:c8:00:05:30:00:f8:e3

Displays the destination switch's domain ID.

To obtain the domain controller address, concatenate the domain ID with FFFC. For example, if the domain ID is 0xda(218), the concatenated ID is 0xfffcda.

Step 2 

switch# fcping fcid 0xFFFCDA vsan 200

28 bytes from 0xFFFCDA time = 298 usec

28 bytes from 0xFFFCDA time = 260 usec

28 bytes from 0xFFFCDA time = 298 usec

28 bytes from 0xFFFCDA time = 294 usec

28 bytes from 0xFFFCDA time = 292 usec

5 frames sent, 5 frames received, 0 timeouts

Round-trip min/avg/max = 260/288/298 usec

Verifies reachability of the destination switch by checking its end-to-end connectivity.

show tech-support Command

The show tech-support command is useful when collecting a large amount of information about the switch for troubleshooting purposes. The output of this command can be provided to technical support representatives when reporting a problem.

The show tech-support command displays the output of several show commands at once. The output from this command varies depending on your configuration. Use the show tech-support command in EXEC mode to display general information about the switch when reporting a problem.

You can choose to have detailed information for each command. You can specify the output for a particular interface, module, or VSAN. Each command output is separated by line and the command precedes the output.


Note Explicitly set the terminal length command to 0 (zero) to disable auto-scrolling and enable manual scrolling. Use the show terminal command to view the configured the terminal size. After obtaining the output of this command, remember to reset your terminal length as required.



Tip You can save the output of this command to a file by appending > (left arrow) and the filename to the show tech-support command. If you save this file, verify you have sufficient space to do so—each of these files may take about 1.8 MB. However, you can zip this file using the gzip filename command. Copy the zipped file to the required location using the copy command and unzip the file using the gunzip command.


The default output of the show tech-support command includes the output of the following commands:

show switchname
