Flow Vision terminology

Table 148

explains the terms used in the discussion of Flow Vision.

TABLE 148

Flow Vision terminology

Term

Description

Defined flow

User-created flow; it can be active or inactive.

Local flow

Flow defined on the switch on which you run the flow.

Root flow

Instance of a static flow used to create learned flows.

Static flow

Flow created without using a learned flow.

Sub-flow

System auto-created flow based on a root flow. There can be more than one sub-flow.

Remote flow

Flow defined on a different switch from the one on which you are viewing it.

Learned flow

Flow defined using an asterisk (*) for the source and destination end devices, which
enables Flow Vision to learn all of the source and destination device pairs passing
through the switch through a specified ingress or egress port without having to identify
all the devices.

Local switch

Switch on which you run the flow.

Remote switch

Switch other than the switch on which you run the flow.

ISL

An Inter-Switch Link (ISL) is a protocol that maintains VLAN information in Ethernet
frames as traffic flows between switches and routers, or switches and switches.

DISL

A Dynamic ISL (DISL) is a physically-connected link between two logical switches that
belong to the same Fabric ID (FID). A DISL is dedicated to carry frames only related to
the FIDs of connected logical switches.

LISL

A Logical ISL (LISL) is a logical link between two logical switches that is used for control
frames. Depending on the fabric topology, a LISL may or may not map directly to a
single physical ISL.

XISL

An eXtended ISL (XISL) is a logical link connecting base switches together to form the
base fabric. It carries frames from the base fabric and other logical fabrics using the
encapsulation and inter-fabric link (IFL) header as identifiers.

Backbone E_Port

The E_Port on a Fibre Channel Routing (FCR)-enabled switch.
