CONTAP-269728: AFF-C250 e0a/e0b port link down with connection to Cisco 9300X-48X
Issue
- The port e0a/e0b link goes down/up when connected to an even number of ports on the Cisco 9300X-48X switch side.
- After the link goes down, it takes more than 10 minutes for the e0a/e0b link to come back up.
- During this period, the port link LED remains green, just like on the Cisco 9300X-48X switch.
- Replacing the cable or the motherboard does not resolve the issue.
