Configuring Vlans - Cisco Catalyst X4232 Installation And Configuration Note

This example shows you how to set the port speed to 100 Mbps on port 2/4:
Console> (enable) set port speed 2/4 100
Port 2/4 speed set to 100 Mbps.
Console> (enable)
This example shows you how to make port 2/4 autonegotiate speed and duplex with the neighbor port:
Console> (enable) set port speed 2/4 auto
Port 2/4 speed set to auto-sensing mode.
Console> (enable)
Setting the Layer 2 Port Duplex Mode
You can set the port duplex mode to full or half duplex for 10/100-Mbps Ethernet ports.
If the port speed is set to auto on a 10/100-Mbps Fast Ethernet port, both speed and duplex
Note
are autonegotiated. You cannot change the duplex mode of ports configured for
autonegotiation. For information on enabling and disabling autonegotiation on 10/100 Fast
Ethernet ports, see the section "Setting the Layer 2 Port Speed".
To set the duplex mode of a port, perform these tasks in privileged mode:
Task
Step 1
Set the port speed of a 10/100-Mbps Fast
Ethernet port.
Step 2
Verify that the duplex mode of the port is
configured correctly.
This example shows you how to set the duplex mode to half duplex on port 2/4:
Console> (enable) set port duplex 2/4 half
Port 2/4 set to half-duplex.
Console> (enable)

Configuring VLANs

After you have configured VTP and specified the Layer 2 interface speed and duplex parameters, you
must create VLANs and assign the ports to the VLANs.
Creating an Ethernet VLAN
To create a new Ethernet VLAN, perform these tasks in privileged mode:
Task
Step 1 Create a new Ethernet VLAN.
Step 2 Verify the VLAN configuration.
