ICX7250 - L3 Premium - Cannot upgrade via TFTP

[oreste_esposito]

Hello,

I am having troubles in upgrading my ICX7250 L3 premium via TFTP.
My ICX has two VRFs: 

SSH@MY-ICX>show vrf detail
Total number of VRFs configured: 2

VRF VRF-DATA, default RD 10.1.255.1:200, Table ID 1
IP Router-Id: 10.1.255.200
Interfaces:
ve100 ve110 ve202 ve201 ve249 ve255 ve50

Address Family IPv4
Max Routes: 750
Number of Unicast Routes: 8
VRF VRF-VIDEO, default RD 10.100.255.1:15, Table ID 2
IP Router-Id: 10.15.170.254
Interfaces:
ve170 ve455

Address Family IPv4
Max Routes: 750
Number of Unicast Routes: 3

Total number of IPv4 unicast route for all non-default VRF is 11
Total number of IPv6 unicast route for all non-default VRF is 0

I don't use default VRF because I want to clearly define my VRFs. I usually manage my switches via ve255. So I taped these commands:

device(config)# ip tftp source-interface ve 255
device#  copy tftp flash 10.7.20.32 SPR08095hufi.bin secondary

I got a timeout; it isn't a firewall problem because I upgraded other switches (same tftp server, tftp client member of the same LAN of interface ve255).

Could you help me please ?

Thanks.

Best regards,
Oreste

Hi Oreste_esposito

Thank you for reaching out to us

From the problem description below are the details I could capture . Correct me if I am wrong. 

• ve255 is used for management purposes. 
• ve255 is part of VRF-DATA

I suppose you can take a working and non working switch and note on the below details. Let me know if this helped in identifying any difference. 

• Please check if you have reachability to ip 10.7.20.32 when you initiate a ping from the switch in question and working switch 
• Try checking the path it takes to reach the TFTP server using traceroute from both working and non working switches 
• Also note if there is any configuration difference related to your management ve255 only 
• In non working check if there also ve255 is used for TFTP updates 
• Also try to do a reachability test from the TFTP server and also note on number of hops it takes to reach the switch 
• Also check if there are firmware difference between both working and non working switch , there switch models. 
• Also check if TFTP server falls in same VRF or different VRF 

I hope this helps. Thanks
