Sie können die Ports konfigurieren und angeben, ob sich der Port im Zugriffs- oder Trunk-Modus befinden soll, und bestimmte Ports VLANs zuweisen. Dieser Artikel enthält Anweisungen zur Konfiguration eines Schnittstellen-VLANs als Zugriffs- oder Trunk-Port auf dem Switch über die Kommandozeile (CLI). Einführun Table 2-4 Cisco Switch Port Configuration The default setting for both duplex and speed for switch ports on Cisco Catalyst 2960 and 3560 switches is auto. The 10/100/1000 ports operate in either half- or full-duplex mode when they are set to 10 or 100 Mb/s, but when they are set to 1000 Mb/s (1 Gb/s), they operate only in full-duplex mode How to configure a trunk port on a Cisco 2960 switch? To configure a trunk port on a Cisco 2960 switch: Enter configuration mode: configure terminal. Specify the port to use: interface <interface-id> Configure the port as a Layer 2 trunk: switchport mode {dynamic {auto | desirable} | trunk} These options mean: dynamic auto - The Default. Creates a trunk link if the neighboring interface is set to trunk or desirable mode To configure and assign a switch access port to a VLAN, open a console connection to the switch and run the following IOS commands from interface configuration mode. omnisecu.com.sw01>enable omnisecu.com.sw01#configure terminal Enter configuration commands, one per line
When you enter the configuration of the Cisco IOS for a switch, the physical ports are logical interfaces, so you specify an interface by describing the physical location of a port. To configure the switch so that you can connect an appropriate device to a port and have it work, follow these steps Die wichtigsten Befehle zur Switchkonfiguration mit Erläuterung.

Although a Cisco switch is a much simpler network device compared with other devices (such as routers and firewalls for example), many people have difficulties to configure a Cisco Catalyst Switch. Unlike other lower class switch vendors (which are plug-and-play), the Cisco switch needs some initial basic configuration in order to enable management, security and some other important features Basic Switch Configuration (2.1) Switches are one of the most numerous devices installed onto the corporate network infrastructure. Configuring them can be fun and challenging. Knowing how switches normally boot and load an operating system is also important. Switch Boot Sequence (2.1.1.1) After a Cisco switch is powered on, it goes through the following boot sequence These sections describe how to configure port security using the Packet Tracer - Configuring Switch Port Security Lab. In this activity, you will configure and verify port security on a switch. Port security allows you to restrict a port's ingress traffic by limiting the MAC addresses that are allowed to send traffic to the port
Configure the interface to the default router. In this scenario you have a Layer 3 FastEthernet port. Switch(config)#interface FastEthernet 0/1 Switch(config-if)#no switchport Switch(config-if)#ip address 200.1.1.1 255.255.255. Switch(config-if)#no shutdown. The no switchport command makes the interface Layer 3 capable. The IP address is in the same subnet as the default router Reset Cisco switch port/interface to default then apply vlan I recently had to wrestle some switch port configurations back to default after applying to dumb settings to them. This was for a Catalyst 3750x in a stack, although it likely applies to many cisco switches

Rowell Dionicio November 25, 2013. A trunk will allow multiple VLANs to transport between switches. Trunk ports can be configured in two ways, the Cisco proprietary Inter-Switch Link, ISL, or with the standard IEEE 802.1Q. Personally, I don't use ISL and you shouldn't either. But lets understand its differences with 802.1Q. Inter-Switch Link (ISL) ISL. In this article we will describe how to configure both LACP and PAgP EtherChannels on Cisco switches. An EtherChannel is a Link Aggregation technology whereby two switches are connected together with multiple interfaces which are bundled together to form a single logical interface (Port-Channel) therefore increasing bandwidth between the switches There are different type of port that you can configure on your Cisco Switch like Access port and trunk port. Access port can carry the traffic of single Vlan only . Access port can be use to connect a PC or IP phone with your Cisco switch. Trunk port can carry the traffic for multiple vlans, Normally these port are use for connecting two switches with each other. Following are basic.

We can configure an access port with an attached Cisco IP Phone to use one VLAN for voice traffic and another VLAN for data traffic from a device attached to the phone. We can configure access ports on the switch to send Cisco Discovery Protocol (CDP) packets that instruct an attached phone to send voice traffic to the switch in any of these way To configure the switch to act as a radius client and port to be unified follow the below configuration template (with respect to your network details, passwords etc.). This type of configuration enables 802.1X and MAB type access (including wired Guest Portal Authentication) Configure a Switch port as a Trunk and connect SwitchA to SwitchB. SwitchB (config)# interface gigabitethernet0/40 SwitchB (config-if)# switchport mode trunk SwitchB (config-if)# switchport trunk native vlan 1 SwitchB (config-if)# switchport trunk allowed vlan add 1,100 SwitchB (config-if)# exit SwitchB (config)# exi The Cisco 4948 switch has four ports that can be configured with any combination of SFP modules with LC connectors, as shown in Figure 4-1. The interface configuration mode command media-type sfp | rj45 can be used to configure the media type for these ports in the switch software and determines whether the SFP or the RJ-45 connector is used. The default is SFP Setting up SPAN ports on Cisco Nexus switches. SPAN ports are commonly used for network traffic analysis applications. SPAN ports work by sending a copy of the traffic destined to one or more ports or VLANs to another port on the switch that has been connected to a network traffic analysis or security device. SPAN mirrors receive or send (or both) traffic on one or more source ports to a destination port for analysis
Switch Port Configuration - Shutdown By default on most Cisco switches, all interfaces will be in an administratively shutdown state. An interface that is shutdown will not send or receive traffic. To take an interface out of a shutdown state: Switch(config)# interface gi3/10 Switch(config-if)# no shutdow Making Configuration Changes On the Switches > Monitor > Switch Ports page, administrators can name ports, turn ports on/off, enable spanning tree (RSTP), define port types (access/trunk), and specify VLANs (data and voice) Starting with Cisco IOS XE 17.1.1, you can configure Per-Port MTU. Per-Port MTU will support port level and port channel level MTU configuration. With Per-Port MTU you can set different MTU values for different interfaces as well as different port channel interfaces. Per-port MTU can be configured in the range of 1500-9198 bytes Learn how to configure a Cisco Switch Link Aggregation using the command-line, by following this simple step-by-step tutorial, you will be able to create a new Link aggregation and configure the link aggregation in access mode or as a trunk that allows the traffic of 2 Vlans

EtherChannel technology allows multiple physical Ethernet links (Fast EtherNet or Gigabit Ethernet) to combine into one logical channel.. There are two protocols used for negotiating EtherChannel and Link Aggregation An Access port can only be assigned to one VLAN & you can configure a switchport as an access port as follows: switch(config)#interface fa0/1 switch(config-if)#switchport mode access switch(config-if)#switchport access vlan 10 switch(config-if)#interface fa0/2 switch(config-if)#switchport mode access switch(config-if)#switchport access vlan 2 Configuring the F-ports on a Cisco FC switch You must configure the F-ports on the FC switch. In a MetroCluster configuration, the F-ports are the ports that connect the switch to the HBA initiators, FC-VI interconnects and FC-to-SAS bridges. Each port must be configured individually. Assigning buffer-to-buffer credits to F-Ports in the same port group as the ISL You must assign the buffer-to.
Port Profiles is a feature of Nexus switches, which allow a template of configuration to apply to a group of ports. This is similar to interface macros in Catalyst IOS. Unlike Catalyst IOS macros, NX-OS port-profiles are event driven, meaning IOS macros apply only once during initial configuration, but P0rt profiles immediately re-apply any time a change is made to the profile Switchport makes the port behave like a Layer 2 port, whereas no switchport will make it behave like a Layer 3 port; is it a toggle. By default, a Layer 3 switch will have all of the ports in Layer 2 mode. By issuing the no switchport command, we will be able to assign IP addresses to Layer 3 ports.

This means that you can buy a Cisco switch, plug in the right cables to connect various devices to the switch, power it on, and the switch will work properly Configuring Cisco Switches for Telnet access. To Configure Switches for telnet access we use the same commands as seen above with one addition. Switches being Layer 2 devices do not have any IP addresses assigned by default, so we'll assign an IP address to a VLAN interface which I'll show you how. Follow the commands belo
Switch Port Configuration: This section covers the configuration steps and commands needed to use Ethernet, Fast Ethernet, and Gigabit and 10-Gigabit Ethernet switch ports in a network. Discovering Connected Devices: This section explains the protocols that can be used to automatically discover other devices that are connected to a Catalyst switch Configuring Trunk Ports. Trunk ports are used for connecting other Cisco switches or Axia devices with switches built-in (like a PowerStation Main or QOR or xSwitch). Please note that when connecting to a PowerStation Main, only the GIG ports can be used, and they must be properly configured for Trunk operation in the Ethernet Switch configuration of the Element Control Center. QOR based devices and xSwitch should only be connected to the GIG Ports LACP allows Cisco switches to manage Ethernet channels between switches that conform the 802.3ad protocol. You can configure maximum 16 ports to form a channel depending on IOS version and platform. Eight of the ports are in active mode and the other eight are in hot-standby mode. There are few LACP modes: active, passive and on
Creating and configuring the VSANs on Cisco FC switches You must create a VSAN for the FC-VI ports and a VSAN for the storage ports on each FC switch in the MetroCluster configuration. The VSANs should have a unique number and name. You must do additional configuration if you are using two ISLs with in-order delivery of frames Trunk ports are used for connecting other switches or Axia devices with switches built-in (like a PowerStation Main or QOR or xSwitch) as well as any other Cisco switches. Please note that when connecting to a PowerStation Main, only the GIG ports can be used, and they must be properly configured for Trunk operation in the Ethernet Switch configuration of the Element Control Center. QOR based devices and xSwitch should only be connected to the GIG Ports and do not require any configuration
Navigate to Configure > Switch ports and choose the specific port to be modified. Using the Type drop down, change the port to access: Configure Data and Voice VLANs. Once the port has been changed to an access port, enter the data and voice VLANs: Configure QoS settings. QoS settings can be enabled on dashboard under Configure > Switch Settings, in the Quality of service section: This rule. We have completed the basic configuration of a Cisco switch. While this is a configured switch, I would highly recommend using more secure passwords than the ones I used. This was done in a lab environment, so I used simple passwords for simplicity. As the title explains, this is just the basics of a Cisco switch. Cisco switches are capable of so much more and we will discuss all of that and. Configure PAgP EtherChannel in Cisco IOS Switch The physical switch ports in PAgP can be configured in one of two available modes in PAgP: - Auto - Passively waits for PAgP to form. If the remote switch port is configured with desirable then only it will form PAgP EtherChannel This is how to configure VLAN on Cisco Switch or Virtual LAN on Cisco Switches in your network. A VLAN is a switched network that is logically segmented by function, project team, or application, without regard to the physical locations of the users. VLANs have the same attributes as physical LANs, but you can group computers even if they are not physically located on the same LAN segment
