CISCO-WIRELESS-P2MP-LINK-METRICS-MIB: View SNMP OID List / Download MIB

This is the MIB Module for the Cisco Wireless Radio Point to MultiPoint interface link metrics specification. Glossary The following terms are used in the MIB definitions below. Radio Interface: The interface that provides wireless communication features. Radio Link: The bi-directional wireless link between two communicating wireless radios. Radio PHY: Represents the transmission characteristics of the Radio link. Link Admin Up: This is the system time when the link is configured to be 'administratively up'. The user can configure the link to be up either by executing a 'no shut' command via the CLI or by setting the ifAdminStatus object in the IF-MIB to 'up(1)' via SNMP. Cisco Wireless MIB Organization The Cisco Wireless Point to Multipoint Radio Link Metrics MIB is divided into 2 main groups. Head End: These objects are supported on the Head End only. Subscriber Unit: These objects are supported on the Subscriber unit only.

This table contains the precision and scale values to be used when interpreting fixed point values in this MIB. This information is encapsulated in a table to accomodate for multiple cards in the same system having different precision values. This table is indexed by the ifIndex for the physical card (propDocsWirelessMaclayer). The user can refer to the entAliasMappingTable in the ENTITY-MIB to determine the upstream/downstream channels associated with each card.

This represents one entry in the p2mpMetricsPrecisionTable. This table is indexed by the ifIndex of propDocsWirelessMaclayer.

This variable indicates the exponent to apply to the fixed-point values.

This variable indicates the number of decimal places used for precision when interpreting the fixed-point values.

This table contains thresholds that are the trigger points to determine if an excessive number of errored codewords are being transmitted. The thresholds can be set for each upstream channel. This helps determine if a particular upstream channel is experiencing excessive errors. The thresholds can also be set for all the subscriber units communicating with the head end. These thresholds will not be set on a per subscriber basis. Instead, there is only one entry in this table for all the subscriber units.

This represents one entry in the tablei. The first entry in this table is applicable to all the subscriber units communicating with the head end. This entry uses the ifIndex of propDocsWirelessMaclayer. Subsequent entries in this table apply to the upstream channels and are indexed by the ifIndex of propDocsWirelessUpstream.

This object represents the threshold for the acceptable ratio of errored codewords to the total codewords transmitted in an operational hour. For an Upstream Channel: When the percentage of errored codewords to total codewords transmitted on a upstream channel crosses this threshold, the p2mpHeChPctErrCWThreshTrap is sent out (provided the number of total codewords transmitted on the upstream channel in an operational hour, exceeds the value represented by p2mpHe1HrMinTotalCWThresh). For a Subscriber Unit (SU): When the percentage of errored codewords to total codewords transmitted by a SU crosses this threshold, the SU is added to a list of SU's that have also crossed this threshold (provided the number of total codewords transmitted by the SU exceed the value represented by p2mpHe1HrMinTotalCWThresh). The head end sends out the p2mpHeMacPctErrCWThreshTrap to indicate that an SU has been added to the 'bad SU list'.

This table lists all the subscriber units who have either failed to transmit a minimum number of codewords in an operational hour OR have transmitted a total number of codewords equal to or greater than p2mpHe1HrMinTotalCWThresh but have a codeword error percentage (ratio of errored codewords to the total number of codewords transmitted) greater than p2mpHe1HrPctErrCWThresh.
