snmp-agent trap enable { static-lsp | ldp | lsp [ mplsxcup | mplsxcdown ] | tunnel-ps | te { tunnel-reop | te-frr [ private ] | hot-standby | ordinary | bandwidth-change } | [ te ] tunnel }
undo snmp-agent trap enable { static-lsp | ldp | lsp [ mplsxcup | mplsxcdown ] | tunnel-ps | te { tunnel-reop | te-frr [ private ] | hot-standby | ordinary | bandwidth-change } | [ te ] tunnel }

By default, the trap function is disabled in the process of the MPLS LSP establishment.
To check the status of an LSP, run the snmp-agent trap enable lsp { mplsxcup | mplsxcdown } command when mplsXCUp or mplsXCDown is enabled.
After the undo snmp-agent trap enable command is run, information about mplsXCUp or mplsXCDown is not displayed, and the status of the trap is unchanged. When you run the snmp-agent trap enable command again, information about the restored trap is displayed.
