Extreme Networks Summit1 manual Port-Mirroring, Verifying the Load Sharing Configuration

CONFIGURING PORTS

When using load sharing, you should always reference the master logical port of the load-sharing group (port 9 in the previous example) when configuring or

viewing VLANs. VLANs configured to use other ports in the load-sharing group will have those ports deleted from the VLAN when load sharing becomes enabled.

VERIFYING THE LOAD SHARING CONFIGURATION

The screen output resulting from the show port config command indicates the ports are involved in load sharing and the master logical port identity.

PORT-MIRRORING

Port-mirroring configures the switch to copy all traffic associated with one or more ports to a monitor port on the switch. The monitor port can be connected to a network analyzer or RMON probe for packet analysis. The switch uses a traffic filter that copies a group of traffic to the monitor port. The traffic filter can be defined based on one of the following criteria:

•MAC source address/destination address — All data sent to or received from a particular source or destination MAC address is copied to the monitor port.

•Physical port — All data that traverses the port, regardless of VLAN configuration, is copied to the monitor port.

•VLAN — All data to and from a particular VLAN, regardless of the physical port configuration, is copied to the monitor port.

•Virtual port — All data specific to a VLAN on a specific port is copied to the monitor port.

Up to 8 mirroring filters and one monitor port can be configured on the switch. Once a port is specified as a monitor port, it cannot be used for any other function.

Frames that contain errors are not mirrored.
