SNMP OID for the MIR Profiles in an ePMP SM

Hi and Happy New Year to All;

How do you confirm and verify which SNMP OID value to use to monitor the MIR Profile.  For example, we have an ePMP Force 180 set with an MIR Profile #: "3".

SNMP OID                                                 Value                        Description

1.3.6.1.4.1.17713.21.3.8.2.29.0     <----      0                              .iso.org.dod.internet.private.enterprises.cambium.pmpMibTree.cambiumpmp80211SystemConfiguration.wireless.wirelessInterface.wirelessMIREnable

{Maximum Information Rate (MIR) Limiting:
0 - Disable,
1 - Enable
Device Alloccation: AP

1.3.6.1.4.1.17713.21.3.8.2.30.0    <------   3            

.iso.org.dod.internet.private.enterprises.cambium.pmpMibTree.cambiumpmp80211SystemConfiguration.wireless.wirelessInterface.wirelessMIRSTAProfileNumber                       

{Maximum Information Rate (MIR) Limiting Profile Number on SM
Device Allocation: SM}

Based on the values (above), it appears that SNMP is showing that the SM has an MIR Profile of "3", however, the MIR is currently disabled.

Which SNMP OID should be used to track, confirm and verify that an SM is using an MIR Profile, the MIR Profile in use and whether it is enabled or not?

What other SNMP OID should be used to confirm the SM MIR rate that is in effect?

Regards.

Hi Lincoln,

Happy New Year to you too!

MIR profiles are managed on AP side.

They can be enabled or disabled on AP only.

In case MIR profiles are enabled on AP every SM will follow default MIR profile #0 with it's default limitations.

To know MIR rate limitations for each SM you have:

1. Check whether MIR profiles are enabled on AP with SNMP OID 

wirelessMIREnable  OBJECT-TYPE
		SYNTAX	   Integer32 (0|1)
		MAX-ACCESS read-write
		STATUS	   current
		DESCRIPTION
		"Maximum Information Rate (MIR) Limiting:
			0 - Disable,
			1 - Enable
		Device Allocation: AP"
		DEFVAL	{ 0 }
		::= { wirelessInterface 29 }

2. Check which MIR profile number is configured on SM with SNMP OID

wirelessMIRSTAProfileNumber	 OBJECT-TYPE
		SYNTAX	   Integer32 (0..15)
		MAX-ACCESS read-write
		STATUS	   current
		DESCRIPTION
		"Maximum Information Rate (MIR) Limiting Profile Number on SM
		Device Allocation: SM"
		::= { wirelessInterface 30 }

 3. Parse MIR entries table on AP

wirelessMIRProfileEntry	 OBJECT-TYPE
		SYNTAX	WirelessMIRProfileEntry
		MAX-ACCESS not-accessible
		STATUS	   current
		DESCRIPTION
		"Maximum Information Rate (MIR) Limiting profile Table Entry
		Device Allocation: AP"
		INDEX	{ wirelessMIRProfileIndex }
		::= { wirelessMIRProfileTable 1 }

WirelessMIRProfileEntry ::= SEQUENCE {
wirelessMIRProfileIndex
Integer32,
wirelessMIRProfileNumber
Integer32,
wirelessMIRProfileDescription
DisplayString,
wirelessDLMIR
Integer32,
wirelessULMIR
Integer32

 And then read wirelessDLMIR and wirelessULMIR with index you got from step#2

wirelessDLMIR  OBJECT-TYPE
		SYNTAX	   Integer32 (100..1000000)
		MAX-ACCESS read-write
		STATUS	   current
		DESCRIPTION
		"DL MIR in kilobits per second
		Device Allocation: AP"
		::= { wirelessMIRProfileEntry 4 }

wirelessULMIR OBJECT-TYPE
SYNTAX Integer32 (100…1000000)
MAX-ACCESS read-write
STATUS current
DESCRIPTION
“UL MIR in kilobits per second
Device Allocation: AP”
::= { wirelessMIRProfileEntry 5 }

Thank you.
