Is it safe to have port 135 open?
It is a sensitive port that is associated with a slew of security vulnerabilities and should never be exposed to the internet. However, Port 135 is needed in an active directory and server/client environment for many services to operate properly.
What is CoPP in Cisco?
The CoPP feature protects the control plane of Cisco IOS Software-based routers and switches against many attacks, including reconnaissance and denial-of-service (DoS) attacks. In this manner, the control plane can maintain packet forwarding and protocol state despite an attack or heavy load on the router or switch.
Is IP a forwarding protocol?
The IP forwarding algorithm is a specific implementation of routing for IP networks. In order to achieve a successful transfer of data, the algorithm uses a routing table to select a next-hop router as the next destination for a datagram. The IP address of the selected router is known as the next-hop address.

What is the purpose of CoPP?
The control plane policing (CoPP) feature increases security on the switch by protecting the RP from unnecessary or DoS traffic and giving priority to important control plane and management traffic. The PFC and DFCs provide hardware support for CoPP. CoPP works with the hardware rate limiters.
