Description

Show all mesh neighbors for an AP.

Syntax

Parameter

Description

ap-name <ap-name>

Show mesh neighbors for an AP with a specific name.

bssid <bssid>

Show mesh neighbors for a specific Basic Service Set Identifier (BSSIDBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly.) on an AP. The Basic Service Set Identifier (BSSIDBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly.) is usually the AP’s MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address.

ip-addr <ip-addr>

Show mesh neighbors for an AP with a specific IP address by entering its IP address in dotted-decimal format.

names

If you include this optional parameter, the Portal column in the output of this command will translate the BSSIDsBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly. of mesh parent and child APs to AP names (where available).

Example

In the example below, the output has been split into two tables to better fit on the page. In the actual CLICommand-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions., the output appears in a single, wide table. The Flags column the output of this command indicates the high-throughput (HTHigh Throughput. IEEE 802.11n is an HT WLAN standard that aims to achieve physical data rates of close to 600 Mbps on the 2.4 GHz and 5 GHz bands.) properties of the mesh node. In the example below, the string “HTHigh Throughput. IEEE 802.11n is an HT WLAN standard that aims to achieve physical data rates of close to 600 Mbps on the 2.4 GHz and 5 GHz bands.-40MHzsgi-2ss” indicates that the node uses a 40MHz channel with a short guard interval (sgi) and sends 2 spatial streams (ss).

The output of this command includes the following information:

Column

Description

MAC

MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address of the mesh node.

Portal

By default, this column displays the BSSIDBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly. of the mesh point. If you include the optional names parameter, this column will display AP names, if available. The AP names will include [p] (parent), or [c] (child) suffixes to indicate the role of the mesh BSSIDBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly..

Channel

Number of a radio channel used by the AP.

Age

Number of seconds elapsed since the AP heard from the neighbor.

Hops

Indicates the number of hops it takes traffic from the mesh node to get to the mesh portal.

The mesh portal advertises a hop count of 0, while all other mesh nodes advertise a cumulative count based on the parent mesh node

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).

Relation

Shows the relationship between the specified AP and the AP on the neighbor list and the amount of time that relationship has existed.

P = Parent

C = Child

N = Neighbor

B = Blacklisted-neighbor

Flags

This parameter shows additional information about the mesh neighbor. The key describing each flag appears at the bottom of the neighbor list.

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 neighbor transmits data to or receives data from the mesh-node specified by the command.

A-Req

Number of association requests from clients

A-Resp

Number of association responses from the mesh node

A-Fail

Number of association failures

Cluster

Name of the Mesh cluster that includes the specified AP or BSSIDBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly..
