Flow Monitor

XISL and backbone E_Port monitors
Flow Monitor supports both static and learned monitoring of fabric-wide statistics on both
XISL_Ports and backbone E_Ports. You can use this data to estimate the logical fabric or
inter-fabric utilization of an XISL_Port or a Backbone E_Port.
The following examples present flow definitions configured with the FCR/XISL mode set to VFID
(virtual fabric ID).
NOTE
This feature is only supported on 16 Gbps-capable platforms running Fabric OS 7.3 or later.
Table 95 details the learned flow support for XISL_Ports and backbone E_Ports
Configuring a specified fabric flow using an XISL E_Port
The following example creates a flow (e2e_src_dcx_xisl) that monitors frames passing from the
source fabric to the destination fabric using a specific port (ingress or egress).
1. Right-click the XISL E_Port on which you want to monitor the flow and select Fabric Vision >
Flow > Add.
The Add Flow Definition dialog box displays with the following default criteria and flow
identifiers pre-populated:
•
Feature — Monitor
•
Direction — Bidirectional
•
Source Device — * (an asterisk allows you to use any port)
•
Destination Device — * (an asterisk allows you to use any port)
•
Ingress/Egress port — XISL E_Port number
2. Enter a name (e2e_src_dcx_xisl) for the flow definition in the Name field.
The name cannot be over 20 characters and can only include alphanumeric characters or
underscores.
NOTE
For a physical switch, the name must be unique. However, for logical switches, the name does
not have to be unique.
3. Select the Persist over switch reboots check box to persist this flow definition over reboots.
4. Select the Activate all selected features check box to immediately activate the flow after
creation.
5. Clear the source port ID in the Source field.
6. Clear the destination port ID in the Destination field.
TABLE 95
Learned flow support for Backbone E_port and XISL_port
Learned traffic Backbone E_Port XISL_Port
Intra-fabric traffic Only learns backbone fabric traffic. Learns logical fabric traffic.
Inter-fabric traffic Learns edge-to-edge, backbone-to-edge, and
edge-to-backbone traffic. Only learns edge-to-edge traffic.
