What does Switchport host command do?
Switchport host command makes: the port an access port, sets the Spanning Tree portfast feature, disables port-channel.
What is the Switchport command?
switchport. You only use the switchport command on switches—not routers. It can put a port into trunk mode, into a certain VLAN, or even to set port security. Its most common use is to configure an interface to connect to an access device (e.g., workstation, server, printer, etc.).
What is Cisco Switchport mode?
It is also Cisco proprietary. switchport mode access – Always forces that port to be an access port with no VLAN tagging allowed EXCEPT for the voice vlan. DTP is not used and a trunk will never be formed. switchport nonegotiate – turns off DTP and forces the interface into a trunk.
What is no Switchport VLAN?
“no switchport” changes the port from being a Layer 2 interface to a layer 3 interface. So a port with “no switchport” is not a member of any vlan, it is as you say a routed port and you can then configure an IP address on it. Hope this answers your question. Jon.
What is the difference between a trunk port and an access port?
An access port is a connection on a switch that transmits data to and from a specific VLAN. A trunk port allows you to send all those signals for each switch or router across a single trunk link. In contrast to an access port, a trunk port must use tagging in order to allow signals to get to the correct endpoint.
What is VLAN configuration?
A VLAN is a group of devices on one or more LANs that are configured to communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. VLANs define broadcast domains in a Layer 2 network.
Why do we use no Switchport command?
As mentioned above, the no switchport command is mainly used to configure routed ports. This helps Layer 3 switch reach the default router during the configuration of VLAN. This prohibits Layer 2 capabilities and enables Layer 3. Then you can assign an IP address to the routed port.
What is the impact of no Switchport command?
The no switchport command puts the interface in L3 mode (known as “routed port”) and makes it operate more like a router interface rather than a switch port. The ip address command assigns an IP address and network mask to the interface. Routed ports can be configured with a Layer 3 routing protocol.
How do you shutdown a Cisco switch?
Pull out the power plug. Cisco’s aren’t like Juniper’s – there’s no “shutdown” command. if the pwoer is on, the switch will be on. You can *disable* it by putting every interface into “shutdown” state if you wish.
What is switchport mode trunk?
Switchport trunk means when you have a trunk link, all VLANs are allowed to pass through a trunk link. To configure a trunk on a switch FastEthernet port, use the switchport mode trunk command. This command puts the interface into permanent trunking mode and negotiates to convert the neighboring switch or links into trunk links.
What is switchport access?
As tubbynet mentioned, “switchport mode access” is a way to force a switch port to always behave as an access port. When the switch port behaves as an access port, it is pretty much acting like consumer-grade switch with no capability of establishing trunks.
