cwrAntennaPolarization
Module: CISCO-WIRELESS-IF-MIB
OID (symbolic): CISCO-WIRELESS-IF-MIB::cwrAntennaPolarization
OID (numeric): 1.3.6.1.4.1.9.9.136.1.10.1.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object represents the electrirc polarization of the antanna.
What is cwrAntennaPolarization?
A read-write INTEGER enumeration (vertical or horizontal) recording the electrical polarization of the antenna. Polarization mismatch between the two ends of a wireless link causes severe signal loss, so this field documents a setting that must match the far end's antenna for the link to work well. For example, if a link's performance suddenly degrades after a physical antenna swap, checking that cwrAntennaPolarization still matches the remote end's polarization is a natural first troubleshooting step.
