The same code works perfectly sometimes. All parameters to the API's are correct though.
I am creating raw packet stack of 'Destination MAC Address-Source MAC Address-VLAN-IPv4'
what would be the root cause for this kind of behavior?
therkong commented 4 years ago

What is the ixNetwork version you're using? Are you using Linux API Server? There is a similar bug opened for ixNet 9.0 Update 1.

kshreep commented 4 years ago

Yes. It's Linux API Server and version: 9.00.2.182

therkong commented 4 years ago

This bug is fixed in ixNetwork 9.0 Update 3. Please give it a try.

therkong commented 4 years ago

You have Update 2. I do have a hotfix for it on top of Update 2. Give me a bit of time to confirm if the bug is fixed in Update 3 or not.

Regards, Theresa

I can send you the hotfix file for the 9.0 Update 2 via ftp. Please send me your email address.

kshreep commented 4 years ago

Thanks @therkong , email is kshreep@gmail.com what's the better way, should I apply hotfix or update IxNetwork? we will be using IxNetwork intensively in our testing.

therkong commented 4 years ago

I’m waiting for engineering team’s reply on whether or not this bug is fixed in Update 3. If it’s fixed, then use Update 3, if not, use the hotfix. This hotfix is verified in the field.
