Hi dear community,
I have a problem with two customers and both are using the 8325-CX-switch.
Some interfaces, which are configured to use a 1500 byte MTU have teir a no-zero jumbo frame counter in TX-direction!
All those interfaces were always configured without jumbo frames. The only interface with jumbo frames enabled is LAG256 for the use with VSX (jumbo is here best practise).
Both customers run different software-versions: 10.08.1010 and 10.10.1050.
What is the reason for a non-zero-counter and what packets could be sent on those interfaces? Is this a bug? Can you reproduce this issue?
One thing I need to add: Up until now I haven't had the time to collect a pcap of the outgoing interface to look for packets! Maybe there are none and the counter is buggy.
