ARM not working?

1. ARM not working?

Kudos

Posted Mar 12, 2024 10:26 AM

I started investigating a problem in Aruba system (many adjacent AP use the same 5GHz channel) and noticed an interesting thing about the ARM statistics. By issuing the "show ap arm rf-summary ap-name" command for each AP, I see that the "Last Check Channel/pwr" and "Last Change Channel/pwr" are almost equal to the AP uptime. Using the "show ap arm history ap-name" command, the history was empty for each AP I checked.
Is this normal? I don't think this is how it should work. What could be the problem, what can I check? In ARM settings everything is on default.

Since your controller is managed by a Mobility Conductor (MCR), your environment is using AirMatch and not ARM.

Are you using AirMatch?

From the MM you can use the "show airmatch solution ap-name" - as well as other optimization commands - to get additional details.

Are you using AirMatch?

From the MM you can use the "show airmatch solution ap-name" - as well as other optimization commands - to get additional details.

Subject: ARM not working?

I started investigating a problem in Aruba system (many adjacent AP use the same 5GHz channel) and noticed an interesting thing about the ARM statistics. By issuing the "show ap arm rf-summary ap-name" command for each AP, I see that the "Last Check Channel/pwr" and "Last Change Channel/pwr" are almost equal to the AP uptime. Using the "show ap arm history ap-name" command, the history was empty for each AP I checked.
Is this normal? I don't think this is how it should work. What could be the problem, what can I check? In ARM settings everything is on default.

Are you using AirMatch?

From the MM you can use the "show airmatch solution ap-name" - as well as other optimization commands - to get additional details.

I started investigating a problem in Aruba system (many adjacent AP use the same 5GHz channel) and noticed an interesting thing about the ARM statistics. By issuing the "show ap arm rf-summary ap-name" command for each AP, I see that the "Last Check Channel/pwr" and "Last Change Channel/pwr" are almost equal to the AP uptime. Using the "show ap arm history ap-name" command, the history was empty for each AP I checked.
Is this normal? I don't think this is how it should work. What could be the problem, what can I check? In ARM settings everything is on default.

Are you using AirMatch?

From the MM you can use the "show airmatch solution ap-name" - as well as other optimization commands - to get additional details.

Subject: ARM not working?

I started investigating a problem in Aruba system (many adjacent AP use the same 5GHz channel) and noticed an interesting thing about the ARM statistics. By issuing the "show ap arm rf-summary ap-name" command for each AP, I see that the "Last Check Channel/pwr" and "Last Change Channel/pwr" are almost equal to the AP uptime. Using the "show ap arm history ap-name" command, the history was empty for each AP I checked.
Is this normal? I don't think this is how it should work. What could be the problem, what can I check? In ARM settings everything is on default.

Reboot the MCR.

Run "airmatch runnow full".

A solution should be generated after a time.

If that doesn't work, open a case with TAC as you've got some sort of issue going on.

Are you using AirMatch?

From the MM you can use the "show airmatch solution ap-name" - as well as other optimization commands - to get additional details.

I started investigating a problem in Aruba system (many adjacent AP use the same 5GHz channel) and noticed an interesting thing about the ARM statistics. By issuing the "show ap arm rf-summary ap-name" command for each AP, I see that the "Last Check Channel/pwr" and "Last Change Channel/pwr" are almost equal to the AP uptime. Using the "show ap arm history ap-name" command, the history was empty for each AP I checked.
Is this normal? I don't think this is how it should work. What could be the problem, what can I check? In ARM settings everything is on default.
