c3gCurrentEvDoEcIo

Module: CISCO-WAN-3G-MIB

OID (symbolic): CISCO-WAN-3G-MIB::c3gCurrentEvDoEcIo

OID (numeric): 1.3.6.1.4.1.9.9.661.1.2.6.3.1.2

Node type: OBJECT-TYPE

Type: C3gEcIo

Access: read-only

Description: Current EV-DO Ec/Io value.

What is c3gCurrentEvDoEcIo?

This read-only value reports the modem's current Ec/Io pilot-quality reading specifically for the EV-DO radio. An admin uses this to detect EV-DO signal quality issues caused by interference rather than distance, which is especially relevant for EV-DO since it's more sensitive to interference-driven throughput loss than 1xRTT. For example, strong EV-DO RSSI combined with poor Ec/Io would explain unexpectedly low EV-DO throughput despite an apparently "good" signal bar.
