show ap mesh topology

show ap mesh topology [long] [page <page>] [start <start>]

Description

Show the mesh topology tree.

Syntax

Parameter

Description

long

Include the names of a mesh portal’s children in the output of this command.

page <page>

Limit the output of this command to a specific number of entries by entering the number of entries you want to display.

start <start>

Start displaying the mesh topology tree at a chosen index number by entering the index number of the AP at which command output should start.

Example

An (N) in the Mesh Role column indicates the node is 11N capable. An (N) beside the parent name in the Parent column indicates that the mesh node’s the parent is also 11N capable.

(host) [mynode] #show ap mesh topology

The output of this command includes the following information:

Column

Description

Name

Name of the mesh node.

Mesh Role

An AP operating as a mesh node can have one of two roles: mesh portal or mesh point.

Parent

If the AP is operating as a mesh point, this parameter displays the name of its parent mesh portal.

Path Cost

A relative measure of the quality of the path from the AP to the controller. A lower number indicates a better quality path, where a higher number indicates a less favorable path (e.g, a path which may be longer or more congested than a path with a lower value.)

For a mesh point, the path cost is the sum of the (parent path cost) + (the parent node cost) + (the link cost).

Node Cost

A relative measure of the quality of the node, where a lower number of is more favorable than a higher number. This cost is related to the number of children on the specified node.

Link Cost

A relative measure of the quality of the link. For example, a more congested link will have a higher link cost than a similar, less-congested link.

Hop Count

Number of hops to the mesh portal.

RSSI

The Receive Signal Strength Indicator (RSSIReceived Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values.) value displayed in the output of this command represents signal strength as a signal to noise ratio. For example, a value of 30 would indicate that the power of the received signal is 30 dBmDecibel-Milliwatts. dBm is a logarithmic measurement (integer) that is typically used in place of mW to represent receive-power level. AMP normalizes all signals to dBm, so that it is easy to evaluate performance between various vendors. above the signal noise threshold.

Rate Tx/Rx

The rate, in MbpsMegabits per second, that a mesh point transmits and receives at on its uplink. Note that the rate information is only as current as indicated in the Last Update column.

Last Update

Time elapsed since the mesh node last updated its statistics.

Uplink Age

Time elapsed since the mesh node became active in the mesh topology.

#Children

Number of children associated with a parent mesh point.
