Rogue endpoint exception list support for bridge domains and L3Outs |
You can create a global rogue/COOP exception list, which excludes a MAC address from rogue endpoint control on all the bridge domains on which the MAC address is discovered, and you can create a rogue/COOP exception list for L3Outs. You can also exclude all MAC addresses for a bridge domain or L3Out. This simplifies creating the exception list when you want to make an exception for every MAC address; you do not need to enter each address individually. |

Cisco Nexus 9000 switch secure erase |
Cisco Nexus 9000 switches utilize persistent storage to maintain system software images, switch configuration, software logs, and operational history. Each of these areas can contain user-specific information such as details on network architecture and design, and potential target vectors for would-be attackers. The secure erase feature enables you comprehensively to erase this information, which you can do when you return a switch with return merchandise authorization (RMA), upgrade or replace a switch, or decommission a system that has reached its end-of-life. |
