Port monitoring

Port monitoring provides the ability to analyze traffic passing through monitored ports by mirroring the traffic from one port to another port on one switch or a switch connected to a network analyzer. The Network analyzer port is the destination for the mirrored traffic. The network analyzer port (the mirrored-to uplink port or downlink port) is for the downlink server ports within a single enclosure. There is a single mirrored-to port per logical interconnect.

Only the available ports are listed in the Network analyzer port drop-down list. Downlink port mirroring is only supported on the physical ports. Once a connection is established to any one of the physical ports on the Mezzanine adapter, then all the ports on that adapter change to Flex mode, and therefore cannot be used as analyzer ports.

Port monitoring is supported only on a physical port and applied only to a downlink port. You can configure port monitoring on a logical interconnect only with the interconnect modules that are in configured state. Ports that are mirrored are known as monitored ports or mirror-from-port. Port where the packets are copied is known as analyzer port or mirror-to-port. The physical interconnect modules of a logical interconnect contain all the port monitoring configurations. To configure port monitoring, specify one or more source ports along with a destination port. The destination port is also known as mirror-to port (MTP).

The MTP receives a copy of the ingress or egress traffic as configured on monitored source ports. The monitored port mirrors the ingress or egress traffic. To monitor the Ethernet traffic direction from a source port, select one of the following options:
  • To server: To monitor only ingress traffic.
  • From server: To monitor only egress traffic.
  • Both: To monitor both ingress and egress traffic.

Port monitoring helps you to mirror traffic from server ports when the physical access to the network interface on the server is limited.

Virtual Connect module uplink ports must not be used as a destination for these externally generated traffic types:

  • Switched Port Analyzer (SPAN)

  • Remote Switch Port Analyzer (RSPAN)

  • Any other mirrored type traffic

Interconnects

You can monitor up to 60 downlink server ports on a logical interconnect. To analyze the Ethernet traffic on monitored ports, use either local port monitoring or remote port monitoring.

You can configure uplink ports as monitored ports to mirror ingress, egress, or traffic in both directions. Ingress is the traffic flowing to the uplink port. Egress is the traffic flowing from the uplink port.

  • Uplink ports and downlink ports can be monitored for both local and remote port monitoring.

  • The same uplink port cannot be configured as both analyzer and monitored port.

  • Only uplinks that are part of an uplink set can be configured for monitoring.

  • Removing a monitored port from existing uplink set is not allowed. The port monitoring must be disabled to remove the monitored port from the uplink set.
