It discusses the need for FHRP to provide redundancy for the default gateway, and describes how HSRP works to elect an active router and standby router to take over if the active router fails. The document outlines the different HSRP router roles, state transitions, and how to configure and tune HSRP, including options for interface tracking, load sharing, and authentication.
This document chapter discusses inter-VLAN routing and provides configuration examples for implementing it using an external router, switch virtual interfaces (SVIs) on a multilayer switch, and routed ports on a multilayer switch. It describes the advantages and disadvantages of each approach and provides a detailed configuration example for configuring inter-VLAN routing using both SVIs and routed ports on a multilayer switch.
This document provides an overview of wide area network (WAN) concepts and technologies for connecting networks. It discusses WAN purposes and operations, as well as both private and public WAN infrastructures. Private WAN options include dedicated technologies like leased lines, frame relay, and MPLS. Public WAN options rely on broadband technologies like DSL, cable, and wireless, secured using VPNs. The document aims to help readers select appropriate WAN services based on business requirements.
The document discusses network troubleshooting techniques. It recommends completing all troubleshooting activities in the chapter, as they will help students preparing for the CCNA exam. The document outlines troubleshooting methodology, including using network documentation, following a troubleshooting process, and isolating issues by layer. It also discusses specific troubleshooting tools, symptoms at different layers, and steps for troubleshooting IP connectivity issues.
The document discusses evolving network technologies including the Internet of Things (IoT), cloud computing, virtualization, and software-defined networking (SDN). It provides an overview of these topics and their importance in modern networks. Specifically, it describes the six pillars of IoT, types of cloud services, cloud deployment models, virtualization techniques, SDN components and controllers, and how policy-based SDN allows for simplified network management.
The document discusses quality of service (QoS) techniques in networking. It covers QoS mechanisms like classification, marking, queueing algorithms, and QoS models. Voice traffic requires low latency, jitter and packet loss, while video and data have different needs. Integrated Services and Differentiated Services are QoS models that allow prioritizing some traffic over others. Classification, shaping, policing and congestion avoidance are tools to implement QoS in a network.
This document discusses network security and monitoring techniques in three sections. Section 5.1 covers LAN security best practices like port security and DHCP snooping to mitigate common attacks. Section 5.2 explains how SNMP allows network monitoring and configuration, including the elements of SNMP and securing SNMPv3. Section 5.3 introduces SPAN as a tool for troubleshooting network issues by duplicating and redirecting traffic to a packet analyzer.
This document provides instructor materials for teaching a chapter on access control lists (ACLs) including:
- Recommendations for instructors to complete assessments and activities to ensure hands-on understanding of ACLs, an important networking concept.
- An overview of the sections and objectives covered in the chapter, including standard and extended ACL configuration and IPv6 ACLs.
- Examples and configuration instructions for standard, extended, and IPv6 ACLs as well as guidance on troubleshooting ACL issues.
This document provides an overview of branch connection technologies including broadband connections like DSL and cable, VPNs, GRE tunnels, and eBGP routing. It discusses selecting broadband technologies based on business requirements, configuring PPPoE, implementing site-to-site and remote access VPNs, establishing GRE tunnels, and configuring eBGP in a single-homed remote access network. The chapter summaries highlight key topics like broadband options, PPPoE, VPN benefits, GRE tunneling, and eBGP design considerations.
The document discusses point-to-point connections and PPP. It covers configuring HDLC and PPP encapsulation on serial interfaces, how PPP operates to establish links using LCP and negotiate network layer protocols using NCP, and troubleshooting techniques for PPP connectivity issues including using debug commands. The chapter summary reiterates key concepts about serial communications, point-to-point links, HDLC, PPP operation, authentication, and multilink PPP.
This document provides instructor materials for a chapter on static routing. The chapter objectives are to explain static routing concepts, configure static and default routes, and troubleshoot static route issues. Static routes are manually configured without a routing protocol. They provide security, use fewer resources than dynamic routing, and are useful for small networks or stub networks with a single connection. The document covers configuring standard static routes, default routes, summary routes, and floating routes in IPv4 and IPv6 along with verifying the configurations. Troubleshooting tips include using ping, traceroute, and checking the routing table.
This document provides an overview of routing concepts and router configuration. It covers the basic functions of routers, including routing decisions, packet forwarding methods, and building routing tables through directly connected networks, static routes, and dynamic routing protocols. The document also describes how to initially configure a router by setting the hostname, interfaces, and verifying connectivity between networks.
This document discusses device discovery, management, and maintenance. It covers using protocols like CDP and LLDP for network discovery. Device management topics include configuring NTP and syslog, while device maintenance includes backing up configurations, restoring files, and upgrading software and licenses.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
Temple of Asclepius in Thrace. Excavation resultsKrassimira Luka
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).
