Nexus 5020 upgrade iOS

Answered Question

Everyone need some help with Nexus 5020


I'm trying to upgrade the iOS software


Here is the problem, I can't seem to copy over the file to the Switch


I have tried these steps please let me know if its incorrect!


copy bootflash:

no go


Copy bootflash tftp:

no go


copy bootflash: filename

no go


I tried WINSCP

no


I have tried cisco device manager " busy network no route or snmpd is unresponsive "

no go


I'm not a networking person but trying to learn and can't seem to get the new bin file copyed over to the switch


Any help would be great


Thanks,

Ed

Simplest thing to do would be to run #: setup


It will run you through the basic setup again, you can put the IP address in, and the GATEWAY in which will fill out the vfc context managment stuff for you.


Then once that is in, you do a copy tftp:10.x.x.x/n5000-uk9.kickstart.5.x.x.x.bin bootflash:n5000-uk9.kickstart.5.x.x.x.bin .


It will ask you what VRF to use, type management

It should then attempt to connect to your TFTP server.


If VRF MANAGEMENT is empty, it has no route out of the box. Are you connecting to this via SSH or on Console?

You can try to put this in first. If the switch takes the commands, do copy tftp://x.x.x.x bootflash: afterward.


conf t

vrf context management

0.0.0.0/0 y.y.y.y <- y.y.y.y is your default gateway/router IP address


HTH,

Firslty you can use any of  SCP/FTP/SFTP/TFTP to copy the image across. You need to able to ping the server that holds the copy of the file. Note also that if you want to copy the file from the server to the switch it would be -


copy tftp bootflash:


rather than


copy bootflash: tftp

Make sure you have a ":" after tftp, here is an example:


copy tftp: bootflash:


Also make sure your tftp server is running. With Nexus 5020, the source interface should be mgmt 0 via the management vrf. You can verify connectivity with ping source from the management interface:


ping x.x.x.x vrf management

The command did not but now I'm getting a new error


I'm able to ping the vrf management ( works )


new error

tftp get operation: failed: no route to host


On the laptop I'm running solorwinds and have

10.1.7.20X

Only one number higher then the switch


the Cisco 5020 mgmt port

10.1.7.20X


I'm able to ping the switch from the laptop no issue.


Thanks,

Ed

Hm... Try this:


copy tftp://10.1.7.20x/ bootflash:


Then answer the question and put the vrf as management and correct file name.


If it doesn't work, post the following command output:

sh run vrf management

sh run int mgmt 0

Can I see this command?


sh run | sec "vrf context"

Okay Ed, I guess something is not working on the show command. Basically, I need the following and here is my output:


vrf context management

  ip route 0.0.0.0/0 192.168.123.1


interface mgmt0

  ip address 192.168.123.151/24

It will only do the change in the management VRF.

Correct Answer

Yah, just run the setup again, it will configure the base system for you if you skip items such as IP or System name it wont change them.


Once you have done that, try and run a cmd like ping... so #: ping xxx.xxx.xxx.xxx vrf management


If you can then ping try running the copy command again #: copy tftp:xxx.xxx.xxx.xxx/tftp_root/file.bin booflash:file.bin

I have the same problem, Trying to upload the licence file .lic to nx 9300 switch. Tried all ftp/scp/tftp, but no joy... pc/switch can ping each other but no file transfer. e.g TFTP error says,

Trying to connect to tftp server......

connection to server established.  (wait for few seconds)

TFTP get operation failed: Connection timeout.

 

If someone can advise on the above issue ?

 

Thanks
