Basic Cisco Switch Configuration

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 ( 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 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.

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

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.
