_bgp_mtp.py	The "BGP_1.3.6.1.2.1.15.0.2 bgpBackwardTransNotification" alarm generated due to BGP peer disconnection triggers the automatic execution of the script. The script performs the ping and tracert operations on the peer IP address and saves the operation results to a diagnostic log, facilitating fault diagnosis.
_isis_mtp.py	Neighbor relationship disconnection triggers the automatic execution of the scripts. The scripts perform the following operations and record relevant information: Ping the IP address of the neighbor to determine the network status. Query IPC/VP packet loss statistics to determine whether inter-board communication is abnormal. Query CP-CAR statistics to determine whether packet loss occurs. Query the CPU usage. Query the reachability of routes to neighbors.
_lacp_mtp.py	The script automatically records information such as the cause of the LACP disconnection, facilitating fault diagnosis.
_ldp_mtp.py	The LDP session Down event triggers the automatic execution of the script. The script pings the peer IP address of the LDP session and saves the ping result and the cause of the session Down event to a diagnostic log, facilitating fault diagnosis.
_ospf_mtp.py	Neighbor relationship disconnection triggers the automatic execution of the scripts. The scripts perform the following operations and record relevant information: Ping the IP address of the neighbor to determine the network status. Query IPC/VP packet loss statistics to determine whether inter-board communication is abnormal. Query CP-CAR statistics to determine whether packet loss occurs. Query the CPU usage. Query the reachability of routes to neighbors.
_ospfv3_mtp.py	Neighbor relationship disconnection triggers the automatic execution of the scripts. The scripts perform the following operations and record relevant information: Ping the IP address of the neighbor to determine the network status. Query IPC/VP packet loss statistics to determine whether inter-board communication is abnormal. Query CP-CAR statistics to determine whether packet loss occurs. Query the CPU usage.
