cwrNumRxAntenna
Module: CISCO-WIRELESS-IF-MIB
OID (symbolic): CISCO-WIRELESS-IF-MIB::cwrNumRxAntenna
OID (numeric): 1.3.6.1.4.1.9.9.136.1.3.2.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object specifies the number of antennas to be used to receive the wireless transmissions.
What is cwrNumRxAntenna?
This read-write INTEGER (1 or 2) specifies how many antennas the radio should use to receive the wireless transmission. Setting it to 2 enables receive diversity, which can improve resilience to multipath fading compared to a single receive antenna. For example, on a long-haul link suffering from intermittent fading, an admin might change cwrNumRxAntenna from 1 to 2 (where a second receive antenna is physically installed) to take advantage of diversity reception.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.136.1.3.2.1.1 snmpwalk -v2c -c public <target> CISCO-WIRELESS-IF-MIB::cwrNumRxAntenna
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.136.1.3.2.1.1.1 snmpget -v2c -c public <target> CISCO-WIRELESS-IF-MIB::cwrNumRxAntenna.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.136.1.3.2.1.1.1 i <value>
