Table of ContentsDescribe VLANs.VLANs on Cisco SwitchesThe default VLANNative VLANManagement VLANA data VLANVoice LANUntagged and Tag VLAN/PortPrivate LANs Every worker in this industry has to have a thorough grasp of the VLAN (Virtual Local Area Network) technology since it is a basic idea in TCP/IP computer networks. VLANs are implemented and set up on Ethernet switches and operate at OSI Layer 2. They are a technique for conceptually separating Layer 2 Ethernet frames created by various network devices such that only frames with the same VLAN ID may interact at the Layer 2 level. A Layer 3 device, such as a router, is required for communication between frames with various VLAN IDs. So, we may manage the traffic across several VLANs using a router (or Layer 3 switch), for example, by utilizing access control lists. By separating the traffic from various devices such that they may only connect at layer 2 with other devices that have been allocated the same VLAN number, this frame separation (and device separation) increases network security. Describe VLANs. A hub or repeater is used in a typical LAN to link workstations to one another. Any data that is received is sent throughout the network by these devices. A collision will happen, and the communicated data will get lost if two users try to send information. Hubs and repeaters will keep spreading the collision once it has taken place throughout the network. VLANs on Cisco Switches A database keeps track of every new VLAN generated on a switch. The vlan.dat file, as it contains this information, is held in the NVRAM or flash memory. On a Cisco switch, the command shows VLAN gets used to display the contents of the VLAN database. All specified VLANS will be lost if the switch's Vlan.dat file gets removed, and the database will be restored to its default settings. The default VLAN The default VLAN for Cisco switches and the massive other switch suppliers is VLAN 1, as it is where all the interfaces get put when a Cisco switch gets switched on for the first time after leaving the factory. All devices connected to the default VLAN can communicate since Ethernet packets are not tagged when leaving the interface. On a Cisco switch, VLAN 1 cannot get erased and is active. It can be perplexing when network managers refer to the VLAN that has been assigned for empty interfaces as the default VLAN since, in reality, this VLAN was chosen as a security best practice for the assignment of interfaces. Native VLAN Trunk interfaces are used to link several switches together. The Ethernet frames from many tagged VLANs can be sent over a trunk interface, as opposed to a regular Access interface, which can only transport traffic for the one VLAN that has been allocated to it. It gets referred to as 802.1q Trunking. In addition to untagged frames like control traffic or traffic from legacy devices that cannot tag their Ethernet packets, the trunk also transmits tagged frames through its link. By default, VLAN 1, the original VLAN, receives all this untagged traffic. A native VLAN can and frequently is given a different number, distinguishing it from the default VLAN. The native VLAN can have any number you choose between 1 and 4094, but it must match both interfaces that link to the trunk. It is an essential point to keep in mind. A native VLAN of 2 on one side and a native VLAN of 3 on the other are incompatible since this would result in a mismatch and prevent communication over the trunk. Management VLAN For the sole purpose of administering infrastructure devices through SSH, HTTPS, SMTP, SYSLOG, etc.,. Any VLAN number the administrator chooses to use. A Layer 3 device, such as a router or multi-layer switch, must be used to construct a Switch Virtual Interface (SVI) and assign an IP Address for the devices in this VLAN to be available for control from a distant computer. Using the management VLAN to divide management traffic from user data traffic complies with best practices. A data VLAN Devices belonging to end users get allocated to the data VLAN. Numerous Data VLANS that can be numbered or named to represent various departments or groups of devices may exist. There may be a VLAN named Finance, followed by a VLAN named Sales, and a third VLAN named Research. A VLAN might get constructed for several devices, such as one for phones or one for audio and video devices called AV. Voice LAN Each desk often has a computer and an IP phone. Two cables would need to be run from each device to the switch if the IP phone, and PC connected to the switch individually. Because the switch's available interfaces would rapidly fill up in a big workplace, Cisco developed IP phones with a tiny switch integrated within the phone's base unit. With the help of this tiny switch, a PC may be connected to a phone, and the phone can then relay traffic from the PC through a single Ethernet connection to a Cisco switch. It is problematic that a switch interface with switchport mode access can only support one VLAN on the interface. Cisco switches allow a conventional Data VLAN to be assigned to the switch port, supporting the computer, and then a Voice VLAN to support a Cisco IP phone, which may get added. When IP packets leave the phone, they get labeled with voice VLAN for IP phones or data VLAN for packets coming from computers. Untagged and Tag VLAN/Port Dot1q tags are optional; packets can either have them or not. Tagged port: A VLAN tag gets required on every packet. Multiple VLANs' traffic gets accepted on this port. It is used most to link switches. Untagged Port: In Cisco, directed--to as the "Access" port. Only permits traffic for a single VLAN. It gets used to link end devices to switches. Some end devices can add a dot1q tag to packets as they leave the device, but massive do not. Determining what happens to the tagging when the packet reaches the switch will thus rely on the type of interface the device is attached to. Private LANs Private VLANS allow devices in the same VLAN to get separated by assigning them a secondary VLAN. An interface will have a main VLAN number allocated to it if a switch gets set up for private VLANs. One of the interfaces in the group will get set up as a promiscuous port. Any other interface can interact with this promiscuous interface, and any interface can respond.

Table of ContentsWhat Is RIP? (RIP Routing Protocol)RIP Versions: RIPv1, RIPv2 & RIPngMetrics & Timers ExplainedBasic Cisco RIP ConfigurationAdvanced RIP FeaturesCatalyst 9400–Specific NotesLimitations & Best PracticesWhen to Use RIPFAQ: RIP on Cisco Devices Routing Information Protocol (RIP) remains a simple and easy-to-configure distance-vector routing protocol—ideal for small networks, labs, or legacy environments. In this guide, we’ll dive deep into how RIP works, how to configure it on Cisco devices, its limitations, and when to use it. What Is RIP? (RIP Routing Protocol) Routing Information Protocol (RIP) is one of the oldest distance-vector routing protocols. It uses hop count as a metric to determine the best path through a network. RIP sends its entire routing table to all adjacent routers every 30 seconds. Key characteristics: Max hop count: 15 (16 = unreachable) Broadcast (RIPv1) or multicast (RIPv2) updates Designed for small, simple networks Defined in RFC 1058 and updated in RFC 2453 RIP Versions: RIPv1, RIPv2 & RIPng RIP has evolved to support modern networking needs through its three main versions: Feature RIPv1 RIPv2 RIPng IP Support IPv4 IPv4 IPv6 Classless ❌ No ✅ Yes ✅ Yes Subnet Masks ❌ No ✅ Yes ✅ Yes Broadcast/Multicast Broadcast Multicast (224.0.0.9) Multicast (FF02::9) Authentication ❌ No ✅ Yes ❌ No RIPv1: Classful, no support for subnet masks, uses broadcast RIPv2: Classless, supports subnetting and route authentication RIPng: RIP for IPv6, uses UDP port 521 Metrics & Timers Explained RIP uses hop count as its routing metric: 0: Directly connected 1–15: Reachable 16: Unreachable (route is dropped) Default timers: Update timer: 30 seconds Invalid timer: 180 seconds Hold-down timer: 180 seconds Flush timer: 240 seconds These timers control how long RIP keeps or removes routes in its table. Basic Cisco RIP Configuration To configure RIP on a Cisco device, use the following commands: enable configure terminal ip routing router rip version 2 no auto-summary network 10.0.0.0 network 192.168.1.0 end show ip protocols Key commands explained: version 2: Enables RIPv2 for subnet support and multicast no auto-summary: Prevents classful network assumptions network: Identifies interfaces that participate in RIP Advanced RIP Features 1. RIP Authentication (RIPv2 Only) For secure RIP updates using MD5: interface GigabitEthernet1/0 ip rip authentication mode md5 ip rip authentication key-chain RIP_KEYS key chain RIP_KEYS key 1 key-string MySecret 2. Split Horizon and Poison Reverse Split Horizon: Prevents routing loops by not sending updates back on the same interface they were received. Poison Reverse: Sends the route back with a hop count of 16 to indicate it's unreachable. To disable split horizon: interface GigabitEthernet1/0 no ip split-horizon 3. Summary Addresses Use manual summarization to reduce routing table size: interface GigabitEthernet1/1 ip summary-address rip 10.2.0.0 255.255.0.0 4. Offset Lists Offset lists allow you to modify the metric for inbound or outbound RIP updates: router rip offset-list 101 in 5 offset-list 101 out 10 5. Tuning Timers You can adjust the default RIP timers to change update intervals: router rip timers basic 45 180 180 240 Catalyst 9400–Specific Notes On Cisco Catalyst 9400 switches: RIP is available with the Network Essentials license. validate-update-source is enabled by default. Triggered updates (in response to changes) are disabled by default but can be configured. Always verify hardware compatibility before deploying RIP in production. Limitations & Best Practices Limitations of RIP: Limited to 15 hops Slow convergence Full routing table updates every 30 seconds (inefficient) Not scalable for large, dynamic networks Best Practices: Use RIPv2 with authentication Disable auto-summary Only use RIP in small, stable networks Use manual summarization to reduce overhead Avoid in enterprise or MPLS networks—prefer OSPF or EIGRP When to Use RIP Scenario Recommendation Small branch/lab network ✅ Yes Legacy router compatibility ✅ Yes Modern enterprise environment ❌ No IPv6 test lab ✅ Yes (RIPng) Backup route in hybrid network ✅ With caution FAQ: RIP on Cisco Devices Q1. What is the difference between RIPv1 and RIPv2? RIPv1 is classful and does not support subnet masks or authentication. RIPv2 is classless, supports subnetting, multicast, and MD5 authentication. Q2. How do I secure RIP updates? Use RIPv2 with MD5 authentication configured via key chains. Q3. Why isn’t RIP used in modern enterprise networks? Due to its limited scalability (15 hops), lack of fast convergence, and outdated design, RIP is not suited for modern dynamic networks.

Table of ContentsWhat Is Network Troubleshooting?What is the significance of network troubleshooting?How do organizations manage troubleshooting?Methods for Troubleshooting:Why Opt for Cisco Training?Simplifying Network Operations with Cisco TrainingConclusion As a network engineer, your main objective is to ensure that all your network hardware is always functioning. But as everyone is aware, equipment might malfunction. It might be due to hardware issues, software discrepancies, or environmental risks. You must determine and pinpoint the malfunction's origin and fix it as quickly as you can under such uncontrollable circumstances. Because of this, it is beneficial to be aware of a few particular strategies that have emerged as significant and fundamental in the realm of networking. However, maintaining and troubleshooting these networks can be a daunting task. It is where the importance of network training, particularly Cisco training, comes into play. What Is Network Troubleshooting? Troubleshooting is the process of locating network issues through a detailed, repeatable procedure and then resolving those issues using techniques that can be put to the test. Since you can target specific network components, test each one for functionality, and are encouraged to record your approach, troubleshooting is more productive than randomly trying things until the network works. A computer hobbyist or prospective network engineer might benefit from learning about network troubleshooting. What is the significance of network troubleshooting? Business resilience is built on quick, efficient network troubleshooting. Networks today handle more crucial corporate operations than ever. Networks may experience expensive downtime due to the lack of thorough investigation and prompt issue resolution. Experiencing downtime can result in reduced productivity, subpar services, data breaches, and malware, which all have financial effects. These effects may have high costs and harm brands in the long run. How do organizations manage troubleshooting? Of course, troubleshooting entails more than simply changing user passwords or restarting hardware. It involves a collection of protocols, practices, and tools used, particularly in big organizations, to handle various requests from a complicated mix of users and scattered network equipment. Large organizations frequently have an entire staff committed to network issues. Tier 1 difficulties, such as password resets, are dealt with by the team's engineers. Tier 2 problems are those that can't be handled by Tier 1, while Tier 3 problems are those that are mission-critical. Tier 1 problem-solving gets contracted out. Requests are efficiently channeled using an escalation architecture, and upper-level engineers are assigned the correct assignments. Automated systems, machine learning (ML), and artificial intelligence (AI) have all been employed to fill skills gaps. These innovations provide Tier 1 engineers with guided remediation tools that enable them to deal with complicated network issues more quickly. The inclusion of these tools may necessitate training and administration by IT teams- numerous organizations already have distinct network diagnostic solutions. A network management system (NMS) is more frequent when network troubleshooting gets integrated. Methods for Troubleshooting: Here are a few more troubleshooting techniques that may be applied to successfully identify the underlying cause of the network issue and put the best fix in place right away. Comparing Configurations Many network performance problems are due to human mistakes, the first step in troubleshooting is to look for network configuration modifications that may have been performed. Implementing the AAA method gives you access to the logs that are kept locally on the device or on an AAA server, which keeps track of these changes. Follow the path The most popular troubleshooting method is to ping the destination device. Another ICMP-based tool, the traceroute, reveals where the ICMP packet terminated in the network. Knowing where your ping ends offers you an edge since it enables you to quickly pinpoint the issue and further investigate the most effective solution for fixing it. Components swappable The most common reason for network disruptions is hardware, which may be anything from a simple ethernet cable wear and tear to a complete equipment breakdown. When this occurs, we are forced to replace the damaged gear with new hardware to keep the network operational. Along with monitoring what happens after the swap, this method is utilized to determine if a particular network device is the root of the problem. Why Opt for Cisco Training?
