Known Affected Releases
Symptom: The link is not coming up when RJ45 SFP is used in A9K-40GE-E or A9K-2T20GE-E linecard. Conditions: Auto-negotiation is not supported in RJ45 SFP. If the far-end device is using Auto-negotiation, then link in GigE interface may be down. This is due to mis-configuration ie., one side is configured for No Auto-neg where as the other side is configured for Auto-neg.
