What is the default speed for Switch ports on catalyst 3560?
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 are designated ports selected for a switch?
> Designated ports are selected based on the lowest path cost to get back to the root switch. Default IEEE port costs include the following: > If two switches have the same cost, the switch with the lowest priority becomes the designated switch, and its port becomes the designated port.
What are the basic switch configuration settings?
This chapter examines some of the basic switch configuration settings required to maintain a secure, available, switched LAN environment. Port configuration starts with the basics of duplex and speed. Sometimes switch ports must manually have their duplex mode and speed manually configured.

What are default ports?
For example, the default port for the HTTP protocol is 80 and the default port for the HTTPS protocol is 443, so a HTTP server waits for requests on those ports. Each Internet protocol is associated with a default port: SMTP (25), POP (110), IMAP (143), IRC (194), and so on.
Which port is used by default?
By default, HTTP uses port 80 and HTTPS uses port 443, but a URL like http://www.example.com:8080/path/ specifies that the web browser connects instead to port 8080 of the HTTP server.

What is default route configuration?
In computer networking, the default route is a configuration of the Internet Protocol (IP) that establishes a forwarding rule for packets when no specific address of a next-hop host is available from the routing table or other routing mechanisms.
What is port configuration?
The Port Configuration window displays the port configuration and provides access to a window for modifying port configuration. Port configuration values are: Port. Slot and port number for each port installed in the switch (for example, A1 means the first port in slot A).

Do switches have default gateway?
The switch uses the IP default gateway only while operating as a Layer 2 device. While routing is enabled on the switch, the IP default gateway is not used.
Do switches need a default gateway?
The switch should be configured with a default gateway if the switch will be managed remotely from networks not directly connected. The default gateway is the first Layer 3 device (such as a router) on the same management VLAN network to which the switch connects.
Does a switch always need a default gateway?
If you want to access the management functions from a remote network, it needs a default gateway. If you don't plan to use the management functions or only plan to use them on the directly attached network, a default gateway is not needed. This all assumes you are not running the switch as a router.
How to Configure Cisco Switches: A Step-by-step Guide - Network Admin Tools
Cisco switches provide outstanding performance, security, scalability, and cost-efficiency for any network type. They are not ordinary plug-and-play devices that do not need configuration or involvement when resolving issues. However, Cisco switches do require an initial setup, ongoing monitoring, and maintenance.
How to configure switch port?
Switch ports can be manually configured with specific duplex and speed settings. Use the duplex interface configuration mode command to manually specify the duplex mode for a switch port. Use the speed interface configuration mode command to manually specify the speed for a switch port. In Figure 2-8 and Table 2-4, port F0/1 on switch S1 and S2 are manually configured with the full keyword for the duplex command and the 100 keyword for the speed command.
What is the default switch speed on a Cisco Catalyst 2960?
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. When troubleshooting switch port issues, the duplex and speed settings should be checked.
What is Mdix auto interface?
With auto-MDIX enabled, either type of cable can be used to connect to other devices, and the interface automatically corrects for any incorrect cabling. On newer Cisco routers and switches, the mdix auto interface configuration mode command enables the feature. When using auto-MDIX on an interface, the interface speed and duplex must be set to auto so that the feature operates correctly.
What type of cable is used to connect a switch to a router?
Until recently, certain cable types (straight-through or crossover) were required when connecting devices. Switch-to-switch or switch-to-router connections required using different Ethernet cables. Using the automatic medium-dependent interface crossover (auto-MDIX) feature on an interface eliminates this problem. When auto-MDIX is enabled, the interface automatically detects the required cable connection type (straight-through or crossover) and configures the connection appropriately. When connecting to switches without the auto-MDIX feature, straight-through cables must be used to connect to devices such as servers, workstations, or routers. Crossover cables must be used to connect a switch to another switch or repeater.
Why are Ethernet packets discarded?
Packets that are discarded because they are smaller than the minimum packet size for the medium. For instance, any Ethernet pack that is less than 64 bytes is considered a runt.
Can a switch port have duplex?
Just as a network card in a PC can have specific conditions such as duplex and speed set, so too can a switch port. This section examines how to configure specific parameters on a Cisco switch port and introduces auto-MDIX.
Do switch ports have duplex mode?
Sometimes switch ports must manually have their duplex mode and speed manually configured. Most of the time the technician simply connects a cable and lets the network device and switch automatically negotiate these parameters. There are also times when things go awry and there are issues.

How to configure switch port?
Switch ports can be manually configured with specific duplex and speed settings. Use the duplex interface configuration mode command to manually specify the duplex mode for a switch port. Use the speed interface configuration mode command to manually specify the speed for a switch port. In Figure 2-8 and Table 2-4, port F0/1 on switch S1 and S2 are manually configured with the full keyword for the duplex command and the 100 keyword for the speed command.
