Ethernet Port Configuration 51
Perform the following configuration in Ethernet Port View.
By default, all traffic is allowed to pass through, that is, no suppression is
performed.
Setting the Link Type for an Ethernet Port
An Ethernet port can operate in three different link types: access, hybrid, and trunk .
An access port carries one VLAN only, used for connecting to the user's computer. A
trunk port can belong to more than one VLAN and receive/send the packets on
multiple VLANs, used for connection between the Switches. A hybrid port can also
carry more than one VLAN and receive/send the packets on multiple VLANs, used for
connecting to both Switches and the user's computers. The difference between a
hybrid port and a trunk port is that a hybrid port allows the packets from multiple
VLANs to be sent without tags, but a trunk port only allows the packets from the
default VLAN to be sent without tags.
Perform the following configuration in Ethernet Port View.
By default, the port is access port.
Note that:
■ You can configure three types of ports concurrently on the same Switch, but
you cannot switch port type between trunk port and hybrid port . You must
return it first into access port and then set it as the other type. For example,
you cannot configure a trunk port directly as a hybrid port, but first set it as an
access port and then as a hybrid port.
