Nexus 3548 No Traffic on a Port

Jun 18, 2019, 12:01 PM

Post #1 of 7 (936 views)

Have any of you seen this behavior with Nexus 3500s or any Nexus? The port just stops passing transmitting after some unknown time. It receives, but no transmit. This appears to migrate to other ports after awhile. A reboot fixes it for a month or so. It's running Cisco NX-OS 7.0(3)I7(3).

What is the port?

There is a certain port on that code that stops passing traffic like 17 or something

Khagendra: have you seen a license for them that’s speed-specific? I’m only aware of the license that enables the second bank of 24 ports... but always at 10gb.
