Full Description:
On August 8, 2023, between approximately 9am and 10am, CIT Network Engineering will enable a network loop-protection feature on building switches served by the Rhodes node on Ithaca campus and the NYTech campus. If a looped device is connected to a CIT switch, the CIT switch port will shut down. Once the loop is corrected, the port will recover and network functionality will return to normal. Network loops are generally the result of customer-owned switches or hubs and devices incorrectly connected to CIT-managed switches. This feature will prevent looped devices from impacting the rest of the building network.
