Module: CISCO-WAN-3G-MIB
OID (symbolic): CISCO-WAN-3G-MIB::c3gHdrDrcCover
OID (numeric): 1.3.6.1.4.1.9.9.661.1.2.2.1.12
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: HDR DRC cover. The DRC cover is a coding applied to identify the sector from which the data is to be transmitted. In one embodiment, the DRC cover is a Walsh code applied to the DRC value, wherein a unique code corresponds to each sector in the Active Set of the AT.
What is c3gHdrDrcCover?
This read-only value reports the DRC cover, a Walsh-code-based identifier applied to the DRC value that tells the network which base station sector in the Active Set the modem is requesting data from. An admin using this alongside c3gSectorId can confirm which specific sector the modem is currently favoring for its EV-DO data requests during handoff or sector-selection troubleshooting. For example, a DRC cover that keeps flipping between values would indicate the modem is rapidly switching its preferred serving sector, possibly due to being near a cell edge.
