Switch Port Analyzer

Device>Configure>Switch Port Analyzer>Copy

You can use switch port analyzer information to gather statistics on traffic between two ports or between a VLAN and a port. This device does allow you to enter a VLAN number as a source. Up to five active Switch Port Analyzer (SPAN) sets (each set is able to contain unlimited source ports) can be supported. For Catalyst 6000, two independent ingress/bidirectional SPANs are active at the same time. For Catalyst 5000 series devices, one ingress/bidirectional SPAN is active and a maximum of four outgoing SPANs are supported. For Catalyst 4000, if the data source is VLAN, the direction must be copyBoth.

Note: The destination cannot be configured as the source.

CONFIGURATION & IMPLEMENTATION TIPS

Use the Switch Port Analyzer window to configure the following information:

SPAN Type (portCopySessionType)

Indicates SPAN type: Local, Remote Source, or Remote Destination.

SourcePorts/VLANs (portCopySource)

Indicates source ports or VLANs.

If the SPAN type is remote destination then it is not applicable (and will be shown as '-').

Destination Port (portCopyDest)

Indicates destination port.

If the SPAN type is remote source then it is not applicable (and will be shown as '-').

RSPAN VLAN (RpanVlan)

Indicates the RSPAN VLAN number.

If the SPAN type is local then it is not applicable (and will be shown as '-'.)

Direction (portCopyDirection)

Direction of monitored traffic. For each SPAN set, use this feature to specify the direction of the packets going through the source ports. The available options are described below:

RX Only (copyRxOnly)

Select this option to have only traffic received on the indicated source port copied to the indicated destination port.

TX Only (copyTxOnly)

Select this option to have only traffic transmitted on the indicated source port copied to the indicated destination port.

RX & TX (copyBoth)

Select this option to have all traffic received and transmitted on the indicated source port copied to the indicated destination port.
