Sure, I'd be happy to explain!
Port security is a feature that allows network administrators to restrict access to a switch port based on the MAC address of the device connected to it. This can help prevent unauthorized access to the network and protect against certain types of attacks, such as MAC address spoofing.
In the case of the Nexus 7000 switch, there are several types of ports that support port security. The three port types that support port security are:
Access ports: These are ports that are configured to carry traffic for a single VLAN. They are typically used to connect end devices such as workstations or servers. When port security is enabled on an access port, the switch will only allow traffic from the MAC address(es) that have been authorized for that port.
Trunk ports: These are ports that are configured to carry traffic for multiple VLANs. They are typically used to connect switches or other networking devices. When port security is enabled on a trunk port, the switch will only allow traffic from the MAC address(es) that have been authorized for the native VLAN.
Layer 2 and Layer 3 ports: These are ports that can be configured to operate at either Layer 2 (Ethernet) or Layer 3 (IP) of the network stack. They are typically used to connect servers or other devices that require both Layer 2 and Layer 3 connectivity. When port security is enabled on a Layer 2 or Layer 3 port, the switch will only allow traffic from the MAC address(es) that have been authorized for that port.
Note that vPC ports, SPAN source ports, and SPAN destination ports do not support port security.
vPC ports are used to create a virtual port channel between two switches, and are not used for end device connectivity. SPAN source ports are used to copy traffic from a source port to a destination port for the purposes of network monitoring or troubleshooting. SPAN destination ports are used to receive the copied traffic from a source port.
I hope this helps! Let me know if you have any further questions.
