How do I monitor traffic ports on a Cisco switch?
You can view the summary or detailed information on the switch ports using the show interface status command. To see the summary information on all ports on the switch, enter the show interface status command with no arguments. Specify a particular module number to see information on the ports on that module only.
What is a routed port?
A routed port acts very much like its name implies. It is a physical port on the switch that has no V information. In place of VLAN information, it has Layer 3 information, such as IP addresses. A rout functions just like an interface on a router.
How do you convert a Switchport to a routed port?
Enabling a switch interface to be a routed interface instead of a switched interface is simple: just use the no switchport subcommand on the physical interface. Cisco switches capable of being a Layer 3 switch use a default of the switchport command to each switch physical interface.
How do I setup a routed port?
Configuring a Routed Port
- Switch(config)#ip routing. Enable IP routing on the router.
- Switch(config)#no switchport. Create the SVI interface or navigate to configuration mode for the interface.
- Switch(config-if)#ip address n.n.n.n subnet-mask. Assign an IP address to the SVI for the VLAN.
What are the root ports?
The Root Port is the port on the Bridge (Switch) with the least Spanning Tree Path Cost from the switch to the Root Bridge. A Designated Port is the port on a Local Area Network (LAN) segment with the least Spanning Tree Path Cost to the Root Bridge (Root Switch). There can be ONLY one Root Port on a Bridge (Switch).
Where can I find port mirroring on a Cisco Catalyst 3560-x?
The only reference I can find to it is configuring via Telnet which I haven’t got a clue about. On my old Wiedmuller switches it was just a few clicks away.
Can a local span session monitor a source port?
In a local SPAN session or RSPAN source session, you can monitor source ports or VLANs for traffic in one or both directions. The switch supports any number of source ports (up to the maximum number of available ports on the switch) and any number of source VLANs (up to the maximum number of VLANs supported).

What does span do to a source port?
SPAN copies (or mirrors) traffic received or sent (or both) on source ports or source VLANs to a destination port for analysis. SPAN does not affect the switching of network traffic on the source ports or VLANs.
