cwrTxRfIndex

Module: CISCO-WIRELESS-IF-MIB

OID (symbolic): CISCO-WIRELESS-IF-MIB::cwrTxRfIndex

OID (numeric): 1.3.6.1.4.1.9.9.136.1.3.1.1.5

Node type: OBJECT-TYPE

Type: CwrRFZeroIndex

Access: read-only

Description: This object specifies the index into the cwrRfTable identifying the antenna used for transmission. This index will be 0 if the associated transmit antenna is not present.

What is cwrTxRfIndex?

This read-only CwrRFZeroIndex identifies, by its index into cwrRfTable, which antenna is used for this radio's transmission, or 0 if no transmit antenna is currently present. It lets an admin correlate this logical radio interface with the specific physical RF resource entry carrying its transmit signal path, including that resource's power, oscillator, and temperature readings. For example, an admin diagnosing weak transmit power would follow cwrTxRfIndex to the matching cwrRfTable row to check cwrRfStatus and cwrRfTxOscState for that specific antenna.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.136.1.3.1.1.5
snmpwalk -v2c -c public <target> CISCO-WIRELESS-IF-MIB::cwrTxRfIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.136.1.3.1.1.5.1
