Upgrading XOS on 440-24p


I'm having some trouble connecting from my switch to my Laptop in order to perform a software upgrade.

I can't ping outbound from the switch using PING VR VR-DEFAULT, I receive 100% loss.
If I try to connect to a TFTP server using TFTP VR VR-DEFAULT I receive an error message stating that there is an invalid input under the V of VR-DEFAULT

Can confirm that both devices are on the same subnet as I can ping from laptop and connect using HTTP

I have also tried using Management port but that is showing as 'DOWN'

Any suggestions?

Thanks Jason ok can you do a show default as well as the IP you are pinging
Userlevel 4
Try the below options
1.Enable Ipforwarding and try tftp download image from another vlan.
Reason:might be problem in current vlan.
2.Assign another ip address to a new vlan and try uploading
3.Make sure no acl's are blocking TFTP.

Hey Jason. Well everything looks great. Can you ping from the device to the switch or can you have another PC on that VLAN and ping to and from that PC. As for the TFTP problem the command for the virtual router uses the -V not vroom so it looks like TFTP [i] -v -g P

Thanks for looking in to this for me. I can ping the switch but I am directly connected via an inband port. I havent put the switch on the network yet as this device will be the 2nd unit in a stack that I am hoping to configure. Therefore I wanted to update the software to same version as the stack 'master' before proceeding, hence the TFTP requirement.

So will my syntax be TFTP -v -g default (somehow that doesn't look right)

Thanks for your help mate.

download image exosversion vr vr-default
Thanks Pathiban.

Much appreciated.
Userlevel 4
TFTP get /put command is to send or receive config and policy files .
Ok. Thanks for the advice. The syntax Parthiban gave me above worked a treat and the switch has now upgraded its software.

Now I'm going to try and create a stack 😉

Thanks for your help chaps.

Hey John sorry I types my last reply from my phone and it didn't come across correctly. Looks like Parthiban got everything set for you. Let us know if there are any other questions. P
Hi Paul,

Everything seems good so far.

I do have a question regarding stacking. 1 node in use and the 2nd node is what I have been working on today.
It looks like I can invoke the Easy Setup Procedure to create the stack, if I do this does it wipe the existing configuration of the node that is currently in use or does it append to the existing configuration?

I would recommend doing a fresh configuration as you are installing a stack for the first time.
If it was an existing stack and you are adding an unit or replacing an RMA unit ,you can follow the steps mentioned in concepts guide in section replacing a node in stack [very clear].

In current scenario:
Check the exos version is same for both the standalone switches.
They both must be in same partition.
Connect the stacking cables and do easy setup.
Reconfigure the stack for vlans and ip's.
As these are low end models ,there might be many vlans and couple of ip's for managing switch.
This reconfig shouldnt be a tedious task.

Its little difficult to mention all the options in here.
15.6 Concepts guide page 136 has details.
Still there are questions or you get stuck please fell free to update.
