Table 38 Setting the Link Type for the Ethernet Port
Operation
Configure the port as a hybrid port
Configure the port as a trunk port
Configure the port as a stack port
Restore the default link type, that is, access port
By default, the port is access port.
Note that:
You can configure four types of ports concurrently on the same Switch, but you
■
cannot switch port type between trunk port, hybrid port and stack port. You
must return it first into access port and the 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.
For the Switch 4500 26-Port and Switch 4500 26-Port PWR,
■
GigabitEthernet1/0/25 and GigabitEthernet1/0/26 ports can be configured as a
stack port; For the Switch 4500 50-Port and Switch 4500 50-Port PWR,
GigabitEthernet1/0/49 and GigabitEthernet1/0/50 ports can be configured as a
stack port.
Adding an Ethernet Port to Specified VLANs
Use the following commands to add an Ethernet port to a specified VLAN. An
access port can only be added to one VLAN, while hybrid and trunk ports can be
added to multiple VLANs.
Perform the following configuration in Ethernet Port View.
Table 39 Adding the Ethernet Port to Specified VLANs
Operation
Add the current access port to a specified
VLAN
Add the current hybrid port to specified
VLANs
Add the current trunk port to specified VLANs port trunk permit vlan {
Remove the current access port from to a
specified VLAN.
Remove the current hybrid port from to
specified VLANs.
Remove the current trunk port from specified
VLANs.
Note that the access port shall be added to an existing VLAN other than VLAN 1.
The VLAN to which a hybrid port is added must already exist. The one to which a
trunk port is added cannot be VLAN 1.
After adding an Ethernet port to specified VLANs, the local port can forward
packets of these VLANs. Hybrid and trunk ports can be added to multiple VLANs,
thereby implementing the VLAN intercommunication between peers. For a hybrid
