rohcUncmprContextState
Module: ROHC-UNCOMPRESSED-MIB
OID (symbolic): ROHC-UNCOMPRESSED-MIB::rohcUncmprContextState
OID (numeric): 1.3.6.1.2.1.113.1.1.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: State of the context. States initAndRefresh(1) and normal(2) are states of compressor contexts, states noContext(3) and fullContext(4) are states of decompressor contexts.
What is rohcUncmprContextState?
This read-only value reports the current state of a Robust Header Compression (ROHC) context, distinguishing compressor states (initAndRefresh, normal) from decompressor states (noContext, fullContext) as defined in RFC 3095. Engineers troubleshooting header-compressed links, common on constrained or wireless WAN links, check this to see whether a given context has successfully synchronized or is still building up state. A context stuck reporting noContext for an extended period suggests the decompressor side is never receiving enough packets to establish full context, likely due to packet loss on the link.
