If the network is not secure, a modem configured on the AUX port enables telephone access. For devices physically distant from the network engineer, network connectivity can be established through two means.
#Cisco switch show mac address table serial
Using Windows hyperterm utility, a serial connection can be established. A console port can be used if the Cisco router or switch is within the same physical proximity of a computer. If a switch does not know which port to route the frame, or the frame is a broadcast, then the frame is routed out all ports except the port where it originated.Īccess to Cisco devices can be accomplished through several means. When a switch receives a frame, the destination MAC address is checked against the table, and the corresponding port is used to route the frame out of the switch. Switches maintain a table of MAC addresses and associated switch port. Use the Cisco IOS show mac-address-table command to examine MAC address and port associations.Use the Telnet protocol to log into a Cisco Switch.Upon completion of this lab, you will be able to: Lab 9.8.2: Cisco Switch MAC Table Examination Lab 11.5.6: Final Case Study - Datagram Analysis with Wireshark.Lab 11.5.5: Network Documentation with Utility Commands.Lab 11.5.3: Configure Host Computers for IP Networking.Lab 11.5.2: Managing Device Configuration.Lab 11.5.1: Basic Cisco Device Configuration.11.4.3.3: Network Latency Documentation with Ping.Lab 10.6.3: Establishing a Console Session with Minicom.Lab 10.6.2: Establishing a Console Session with HyperTerminal.Lab 10.6.1: Creating a Small Lab Topology.9.9.1: Skills Integration Challenge-Switched Ethernet.Lab 9.8.3: Intermediary Device as an End Device.Lab 9.8.2: Cisco Switch MAC Table Examination.Lab 9.8.1: Address Resolution Protocol (ARP).Lab 8.4.1: Media Connectors Lab Activity.7.6.1: Skills Integration Challenge-Data Link Layer Issues.Lab 6.7.5: Subnet and Router Configuration.Activity 6.7.4: IPv4 Address Subnetting Part 2.Activity 6.7.3: IPv4 Address Subnetting Part 1.5.6.1: Skills Integration Challenge-Routing IP Packets.Lab 5.5.1: Examining a Device’s Gateway.Lab 4.5.3: Application and Transport Layer Protocols Examination.Lab 4.5.2: TCP/IP Transport Layer Protocols, TCP and UDP.Lab 4.5.1: Observing TCP and UDP using Netstat.Lab 3.4.3: E-mail Services and Protocols.2.7.1: Skills Integration Challenge-Examining Packets.Lab 2.6.2: Using Wireshark™ to View Protocol Data Units.Lab 2.6.1: Topology Orientation and Building a Small Network.Activity 2.2.5: Using NeoTrace™ to View Internetworks.1.7.1: Skills Integration Challenge-Introduction to Packet Tracer.Lab 1.6.2: Using Collaboration Tools-Wikis and Web Logs.
