Cisco WAE Design 7.0.1 User Guide

Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Interfaces and Circuits

 

Table 29-1 Interface and Circuit Visualization

Graphic
Description

 

Circuits are rectangles divided in half by a vertical black line. Each half shows an interface. Tick marks show 25%, 50%, 75% utilization levels.

 

Width of circuit shows capacity. Width increases a fixed amount for every 4x increase in capacity.

 

Full-length interface style, which is the default.

 

Shortened interface style, showing the same information as a full-length view, just in shorter representations that are repeated at each end of the circuit.

In this example, all chi interfaces are shortened at both ends of the circuit.

 

Collapsed interface view, showing the presence of interfaces as up/down arrows inside the site. The arrow color shows the highest utilization of any of the collapsed interfaces (in this example, blue for sea and yellow for chi).

In this example, all chi interfaces are collapsed at both ends of the circuit.

Circuit Colors

 

Table 29-2 Interface and Circuit Colors

Graphic
Description

The traffic utilization colors are customizable. For information, see the Cisco WAE Network Visualization Guide.

 

Blue indicates a selected interface or circuit.

 

Outbound traffic utilization is depicted by colors. Default colors are light blue, light green, yellow, orange, red, and purple, and left to right, each color represents increased utilization.

  • Measured Traffic and Simulated Traffic views—The color shows the percent of traffic utilized for the available interface capacity.
  • Worst-Case Traffic view—The color represents the worst-case utilization on each interface. This is the highest utilization that a particular interface experiences over all the failure scenarios considered when running a simulation analysis.
  • Failure Impact view—The color represents the failure impact of a circuit. This is defined as the highest utilization experienced by any interface if that circuit were to fail.
  • LSP Reservation view—The color represents the total setup bandwidth that is reserved by LSPs through the interface.

 

If parallel circuits are grouped for visual display, each side of the circuit shows its constituent interfaces. Here, there are two circuits (two interfaces on each side) grouped by site. If the circuits are between sites, the utilization includes the utilization of nested interfaces, if applicable.

  • The color fill on each side shows the average utilization of the grouped interfaces, which is weighted against the sum of the grouped capacities. For example, the average utilization for the interfaces from chi to mia is between 30% and 50% and is shown in green.
  • Each interface within a grouped circuit has a thin colored border showing the utilization of that interface. For example, one interface going from mia to chi is bordered by yellow and another by blue, each showing the traffic utilization for the bordered interface.

 

White indicates 0% utilization.

 

Interfaces are light gray for the following reasons:

  • Measured Traffic view

– The interface has no traffic measurement.

– This amount of interface capacity is not available due to a QoS bound.

  • Simulated Traffic view—This amount of interface capacity is not available due to a QoS bound.
  • Worst-Case Traffic view—No simulation analysis was performed.
  • Failure Impact view

– No simulation analysis was performed.

– Failing the circuit would not increase the traffic utilization on any other circuit.

  • Circuit is operationally down.

 

QoS policy violations are indicated by red and white bars. This is displayed when utilization exceeds the QoS bound, which is set through policy or interface queue properties.

 

Shortest IGP path between two selected nodes or sites.

 

Shortest latency path between two selected nodes or sites.

 

Shortest TE path between two selected nodes or sites.

Circuit Active, Failed, and Operational States

 

Table 29-3 Circuit Active, Failed, and Operational States

Graphic
Description

 

Failed circuit.

 

The circuit is not operational because of one of the following reasons:

  • A node connected to the circuit failed.
  • A site failed that contains a node connected to the circuit.
  • The circuit is a LAG (port channel) that does not meet its operational requirements (minimum number of available ports or minimum capacity, whichever is surpassed first) due to failure of some of its ports or port circuits.
  • Mapped L1 circuit cannot be routed because it traverses a failed L1 port, L1 node, or L1 link.
  • An SRLG failed that contains the circuit or contains one of the above objects that are required for circuit operation.

 

The circuit is a LAG, and one or more ports or port circuits in the LAG failed. The red strikeout line is the percent of unavailable capacity due to the failure. In the Worst-Case Traffic view, the red strikeout line is the percent of unavailable capacity under the worst-case failure.

If you right-click the failed port or port circuit and choose Recover, the red strikeout line disappears. If you right-click again and choose Fail, the red strikeout line returns.

 

The circuit is inactive.

 

The circuit is not operational because of one of the following reasons:

  • A node connected to the circuit is inactive.
  • An inactive site contains a node connected to the circuit.
  • The circuit is a LAG that does not meet its operational requirements (minimum number of available ports or minimum capacity, whichever is surpassed first) due to some of its ports or port circuits being inactive.
  • A mapped L1 circuit cannot be routed because it traverses an inactive L1 port, L1 node, or L1 link.
  • An SRLG is inactive, and the SRLG contains the circuit or contains one of the above objects that is required for circuit operation.

 

The circuit is a LAG and one or more ports or port circuits in the LAG is inactive. The gray strikeout line is the percent of unavailable capacity due to the inactive ports or port circuits.

L3 Nodes

 

Table 29-4 Layer 3 Node Visualization

Graphic
Description

 

A node is shown as a blue rectangle with a border. Solid blue indicates the node is selected.

 

A green border surrounds the node when:

  • Simulated Traffic View—The node is the source or destination of simulated traffic that is greater than 0.
  • Measured Traffic View—The node is the source or destination of measured traffic that is greater than 0.
  • LSP Reservation View—The node is the source or destination of LSPs with nonzero bandwidth reservations.

 

A white border surrounds the node when:

  • Simulated Traffic View—The node is not the source or destination of simulated traffic.
  • Measured Traffic View—The node has ingress and egress traffic of 0 (zero).
  • LSP Reservation View—The node is the source or destination of LSPs with 0 (zero) bandwidth reservations.

 

A gray border surrounds the node when:

  • Measured Traffic View—The node has no ingress or egress traffic.
  • Worst-Case Traffic View—Nodes always have gray borders.
  • Failure Impact View—The node is not included in the failures considered, or failing the node would not increase the traffic utilization on any circuit.

 

In the Failure Impact view, the node border color represents the failure impact of a node. This is defined as the highest utilization experienced by any circuit if that node were to fail.

 

Up/down triangles show that some interfaces from the node have been collapsed.

 

Failed node.

 

Node is not operational because it is contained in a failed site or in a failed SRLG.

 

Node is not active.

 

Node is not operational because it is contained in a site or an SRLG that is not active.

 

One or more selected VPN nodes exist on the node.

Sites

Site utilization colors and symbols are based on intrasite objects. Note that intrasite objects include child sites and the objects contained within them.

Graphic
Description

 

A site is shown as a blue square with a border. Solid blue indicates the site is selected.

 
  • Layer 3 view

– Measured Traffic and Simulated Traffic views—The border color is the maximum traffic utilization color of all intrasite interfaces within the site.

– Worst-Case Traffic view—The border color is the highest utilization that the interfaces within it experience over all the failure sets selected for Simulation Analysis.

– Failure Impact view—The border color is the maximum utilization level that would be caused elsewhere in the network should an L3 node or L3 circuit contained within it fail.

  • Layer 1 Failure Impact view—The border color is the maximum utilization level that would be caused elsewhere in the network should an L1 node or L1 link contained within it fail.
  • Multi-Layer Failure Impact View—The border color is the maximum utilization level that would be caused elsewhere in the network should any L1 or L3 intrasite object fail.

 
  • Layer 3 view—A white border surrounds the site if all intrasite interfaces have zero utilization.
  • Layer 1 view—The sites always have white borders except in Failure Impact view.

 

A gray border surrounds the site when:

  • Layer 3 view

– Measured Traffic view—There is no measured traffic on intrasite interfaces.

– Worst-Case and Failure Impact views—No simulation analysis was performed.

– Failure Impact view—Failing an intrasite L3 node or L3 circuit would not increase the traffic utilization on any L3 circuit.

  • Layer 1 Failure Impact view—Failing an intrasite L1 node or L1 link would not increase the traffic utilization on any L3 circuit.
  • Multi-layer Failure Impact view—Failing an L1 or L3 intrasite object would not increase the traffic utilization on any L3 circuit.
