vdx-6740 firmware/nos update via ftp, scp, sftp does work.

[Pawel_Eljasz]

hi everyone,

I have a switch from which I can ssh into ftp server, that is on a vlan. Other nodes on that vlan can ftp into that server okey.
The same switch I can ssh into its management interface cannot ping back that node from which I ssh. (that's is weird right?)

Now, when I try "firmware download" (on the vlan, obviously) via ftp, sftp, scp it all fails, example:

sw0# firmware download ftp host 10.5.4.97 directory nos7.2.0a1 user anonymous
Password: *********
Performing system sanity check...
The server is inaccessible or firmware path is invalid. Please make sure the server name or IP address, the user/password and the
firmware path are valid.

I can see that the switch does not even get to the ftp server, again, I can ssh from the switch to that IP address. SPC does not work neither.

sw0# firmware download scp host 10.5.4.97 directory /home.sysops/appmgr/nos7.2.0a1 user appmgr
Password: ************
Performing system sanity check...
The server is inaccessible or firmware path is invalid. Please make sure the server name or IP address, the user/password and the
firmware path are valid and the server supports SSH password authentication.

Because it's just my first foray into Brocade I hope, expect, I'm missing something and it's not some bad fault, malfunction on switch's part.

What is it that I am missing, doing wrong?

many thanks, L.

Yes, on NOS6.x upgrade should be via mgmt vrf, on NOS7.x you can choose which vrf to use.

hi Yulia,

okey, now, why would I want to ping an IP on a vlan from management interface?
Are you saying that firmware updates can only be done via this interface?

And why switch be unsuccessful pinging the client from which I'm sshing into the switch? (and that is direct attach link, no other switches in between, but also the same with other switches in between)

Here is my switch:

sw0# show version Network Operating System Software Network Operating System Version: 6.0.2 Copyright (c) 1995-2015 Brocade Communications Systems, Inc. Firmware name: 6.0.2e Build Time: 10:42:08 Apr 10, 2017 Install Time: 12:25:22 May 30, 2017 Kernel: 2.6.34.6 BootProm: 1.0.1 Control Processor: e500mc with 4096 MB of memory Slot Name Primary/Secondary Versions Status --------------------------------------------------------------------------- SW/0 NOS 6.0.2e ACTIVE* 6.0.2e SW/1 NOS 6.0.2e STANDBY 6.0.2e And there is just one vlan with interface and IP 10.5.4.253.
Mgmt iface is 10.214.234.95.

It really should be simple, right?
Because switch cannot even ping anything on mgmt interface that disqualifies it to use for network firmware updates, I assumed, no?

So I use switch's vlan interface with ftp, etc. Not that I use, I assume that switch does it for it's not stupid and since I can ping and ssh from the switch to that 10.5.4.97 server.

It does not seem to be an option for vrf in switch current NOS version.

Again, when I try "firmware download" whether ftp, sftp, scp I'm watching server's end and it does not even look like switch gets to the server !?
Other nodes which are connected to switch on that one single vlan do scp, ftp and sftp to that 10.5.4.97 just fine.

Because you didn't provide a lot of information about the network e.g. a network diagram or a full switch config we assume things that are not mentioned.

Use the right vrf if it isn't the mgmt one.

If the works use also the vrf option in the download cmd.

Hi L,

For upgrade from FTP server:
1. please try create user/password (sometimes anonymous doesn't work)
2. please try to map nos7.2.0a1 folder as User directory (then use "/" as directory)

Example:
# firmware download ftp host 10.5.4.97 directory / user admin password admin123 You can try ping ftp server from switch
#ping 10.5.4.97 vrf mgmt-vrf
