What is the difference between a trunk port and an access port?

What is the difference between an access port and a trunk 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.

Can a switch port be used to connect a router?

Re: Switch port mode to connect a router. You can connect either a trunk port or an access port to a router. If you choose to use an access port, the router will form an adjacency only over the VLAN defined in that access port. If you choose a trunk port, you can use dot1q encapsulation on subinterfaces to form adjacencies over multiple VLANs.

Can a router use a trunk port instead of an access port?

If you choose to use an access port, the router will form an adjacency only over the VLAN defined in that access port. If you choose a trunk port, you can use dot1q encapsulation on subinterfaces to form adjacencies over multiple VLANs. If you using a trunk you would do this type of configuration: ! ! Here is a good tutorial on it:

Which is the default access group mode in Cisco?

Merge mode—In this mode, the PACL, VACL, and Cisco IOS ACLs are merged in the ingress direction following the logical serial model shown in Figure 51-2. This is the default access group mode. You configure the access-group mode command on each interface. The default is merge mode.

Can a Cisco router be used as a host Gateway?

Cisco documentation on the feature: To answer your question, you can use the router as the default gateway for hosts. In the that case it would not be required to have an SVI on the switch except for MGMT purposes. Traffic from hosts would take the L2 path to the router and then the router would make the next forwarding decision for the packet.
