Resolved Alert:
Initial Symptoms
Reported to Data Center operations team by Support Center that security cameras had some issues.
Root Cause Analysis
Cause
Plugging Cisco SFPs into DATA-01-A-SW71 and DATA-01-A-SW72, the incompatibility between SFPs and switches caused issues to uplinks of the switches.
Resolution
1. Removed the SFPs from the switches
2. Disabled and re-enabled the switch uplinks to the PE router
3. Rebooted DATA-01-A-SW72
Prevention
For datacenter devices, anytime we put in a new type of SFP, we will create a RFC and do the work during a maintenance window.
