CCNA: Access-Lists (Standard and Extended)

 In Cisco networking, an access list (or ACL) is a set of rules that defines what traffic is allowed or denied to pass through a network device, such as a router or switch. Access lists are used to filter and control network traffic based on criteria such as source and destination IP addresses, protocols, and ports. Access lists can be applied to inbound or outbound traffic on an interface, and they can be used to permit or deny traffic.

Access lists are identified by a number, which can range from 1 to 199 for standard IPv4 access lists, 100 to 199 for extended IPv4 access lists, 2000 to 2699 for standard IPv6 access lists, and 2700 to 2799 for extended IPv6 access lists.

There are two types of access lists in Cisco networking:

Standard access lists: These access lists match traffic based on the source IP address only. They are identified by a number from 1 to 99 (IPv4) or 1300 to 1999 (IPv6).

Extended access lists: These access lists match traffic based on multiple criteria, such as source and destination IP addresses, protocols, and ports. They are identified by a number from 100 to 199 (IPv4) or 2000 to 2699 (IPv6).

CCNP ENCOR Certification Cram Notes : Network Assurance

 Network Assurance is the process of ensuring that a network is functioning properly, reliably, and securely. It involves a range of activities that help network administrators to proactively monitor, analyze, and optimize their networks for better performance.

Some of the key components of Network Assurance include:

Network Monitoring: This involves continuously monitoring the network for potential issues, such as traffic congestion, packet loss, and device failures. Network administrators use various tools, such as network monitoring software, to monitor network traffic and detect any anomalies.

Network Analysis: This involves analyzing network data to identify patterns and trends that could help improve network performance. Network administrators use various tools, such as network analyzers, to collect and analyze network data.

Network Optimization: This involves optimizing network configurations to improve network performance and security. Network administrators use various tools, such as network management software, to configure and optimize network devices, such as routers and switches.

Network Security: This involves implementing measures to protect the network from unauthorized access, malware, and other security threats. Network administrators use various tools, such as firewalls and intrusion detection systems, to protect the network.

Overall, Network Assurance is an essential component, as it helps network administrators to ensure that their networks are reliable, secure, and functioning at optimal levels. By proactively monitoring, analyzing, and optimizing their networks, network administrators can reduce downtime, improve user experience, and increase network efficiency.
