Hi Raghu,

Thanks for reaching out.

If switch "DCS-7050QX-32S-F" in your network environment is an MLAG device/peer then you need to follow MLAG ISSU procedure and if it is a standalone device then we can directly upgrade to the target release(i.e 4.24.5M) without the need of an intermediate EOS version.

For MLAG device upgrades, you can check the ISSU compatibility matrix from the below link:

https://www.arista.com/en/support/mlag-portal/mlaglist

 

Since 4.14.16M EOS version is very old and out of support we recommend you to raise a case with Arista TAC by dropping a mail to support@arista.com and TAC can further help you regarding this.

 

Thanks,

Bhavana.

Hello @

I have an Arista 7050S and a 7050TX in my environment and the questions are;
1. Are the EOS command universal across all versions of the Arista 7050 series switches?
i.e can I run the same ESO version in the above switch types?

2. What is the difference between 7050TX and 7050S?
i.e Is there a document that explains the naming convention?

Thank you.

Hi Raghu,

      Thank you for your response. Please find the answer for your query inline:

1. Are the EOS command universal across all versions of the Arista 7050 series switches?

i.e can I run the same EOS version in the above switch types?

Ans: In general we should be able to use the same EOS version across all 7050 series switches.

However, we highly recommend you to check the release notes of the EOS version for the hardware compatibility.

2. What is the difference between 7050TX and 7050S?

i.e Is there a document that explains the naming convention?

Ans: Please refer to the below datasheets:

Hello @Raghu,

Thank you for providing me with the links above.

However, I am afraid the answer to question 2 above is not in the link.

What I meant was, what is the meaning of the suffixes attached to the switches?

e.g TX, SX, QX. If there is a document where its explained, please share.

Thank you.

Also, A few things I would appreciate clarity on.

  1. Is EOS backup possible? I have seen commands for backing up the configuration files but no mention was made of the EOS file backup.
  2. Is there a vlan.dat file as is with cisco switches? If yes, please where can I find the file?
  3. Can I have a mixture of different switch types in a stack? e.g 7050TX and 7050SX in the same stack?

 

Thank you.

Hello Obioma,

Please find the answers provided below: 

1. What I meant was, what is the meaning of the suffixes attached to the switches? e.g TX, SX, QX. If there is a document where its explained, please share.

[Answer] The platform is 7050X. Depending on the type of ports on the switch we would see T,S or Q. When the port type is Rj45(Copper), the device would be a 7050TX. For port type SFP/SFP+(Fiber), the device would be 7050SX and for port type QSFP, the device would be 7050QX. 

2.  Is EOS backup possible? I have seen commands for backing up the configuration files but no mention was made of the EOS file backup. 

[Answer] The EOS images reside on flash and have a .swi extension. The current running image of the device can be found by checking the boot-config:

Switch#show boot-config

Software image: flash:/EOS-4.21.8M.swi

Console speed: (not set)

Aboot password (encrypted): (not set)

Memory test iterations: (not set)

3. Is there a vlan.dat file as is with cisco switches? If yes, please where can I find the file?

[Answer] In Cisco devices a vlan.dat file is created if you have VTP configured. Arista EOS doesn’t support VTP so we do not have a vlan.dat file.All the vlan configuration is part of running-config on Arista switches.

4. Can I have a mixture of different switch types in a stack? e.g 7050TX and 7050SX in the same stack?

[Answer] Arista supports an Active/Active mode using a feature called MLAG (Multi-chassis LAG)  and not switch stacking. 

This means at a time we can use only two switches to form an mlag and hence provide redundancy. For more information on Mlag please check the following link:

Hope this helps.

Hello @Keerthi Bharathi,

Thank you for the explanations above.

One more question though.

Using my PC as my FTP server, what is the procedure for backing up EOS?

Thank you.

Hello Obioma,

To copy the EOS image to your pc. Please make sure that there is reachability from your switch to the PC.

Use the following command to copy:

copy flash:/EOS.swi ftp://<ip_address_of_ftp>/EOS.swi

Please note: In the above command, you can replace the words EOS.swi with whichever EOS image file you want to copy or backup.

Hope this helps.
