+.TH GOVPP-SNMP-AGENTX 1 "June 2025" "version 1.0.0" "User Commands"
+.SH NAME
+govpp-snmp-agentx \- VPP SNMP AgentX daemon for interface statistics
+.SH SYNOPSIS
+.B govpp-snmp-agentx
+[\fIOPTION\fR]...
+.SH DESCRIPTION
+.B govpp-snmp-agentx
+is an SNMP AgentX subagent that provides SNMP access to VPP (Vector Packet Processing) interface statistics and information. It connects to a master SNMP daemon via the AgentX protocol and populates standard IF-MIB tables with real-time VPP interface data.
+.PP
+The daemon implements two MIB tables:
+.TP
+.B ifEntry
+Classic interface table (1.3.6.1.2.1.2.2.1) with basic interface statistics including counters for packets, bytes, errors, and discards.
+.TP
+.B ifXTable
+Extended interface table (1.3.6.1.2.1.31.1.1.1) with high-capacity 64-bit counters and additional interface information.
+.SH OPTIONS
+.TP
+.BR \-agentx.addr " " \fIADDRESS\fR
+AgentX master agent address. Can be a TCP address (hostname:port) or Unix socket path.
+Default: localhost:705
+.TP
+.BR \-debug
+Enable debug logging to show detailed operational information.
+.TP
+.BR \-vppcfg " " \fIFILE\fR
+VPP configuration YAML file to read interface descriptions from.
+.TP
+.BR \-vppstats.api.addr " " \fIPATH\fR
+VPP API socket path for interface enumeration.
+Default: /var/run/vpp/api.sock
+.TP
+.BR \-vppstats.stats.addr " " \fIPATH\fR
+VPP statistics socket path for interface counters.
+Default: /var/run/vpp/stats.sock
+.TP
+.BR \-vppstats.ifindex-offset " " \fINUMBER\fR
+Offset added to VPP interface indices for SNMP interface numbering.
+Default: 1000
+.TP
+.BR \-vppstats.period " " \fISECONDS\fR
+Interval in seconds for querying VPP interface statistics.
+Default: 10
+.SH EXAMPLES
+.TP
+Connect to AgentX master via TCP:
+.B govpp-snmp-agentx -agentx.addr snmp.example.com:705
+.TP
+Connect via Unix socket with debug logging:
+.B govpp-snmp-agentx -agentx.addr /var/agentx/master -debug
+.TP
+Use custom VPP sockets and config:
+.B govpp-snmp-agentx -vppstats.api.addr /opt/vpp/api.sock -vppcfg /etc/vpp/vppcfg.yaml
+.SH FILES
+.TP
+.I /var/run/vpp/api.sock
+Default VPP API socket
+.TP
+.I /var/run/vpp/stats.sock
+Default VPP statistics socket
+.TP
+.I /var/agentx/master
+Common AgentX Unix socket path
