Usage Guidelines

Usage Scenario

To view LDP LSP manager debugging information, run the debugging mpls ldp lsp command. The debugging information helps check whether the packet format is correct and whether the packets are transmitted properly if an LDP LSP fails.

Example

# Enable partner debugging of the LDP LSP manager.

<HUAWEI> debugging mpls ldp lsp partner

# Enable event debugging of the LDP LSP manager.

<HUAWEI> debugging mpls ldp lsp events

# Enable the error debugging of the LDP LSP manager.

<HUAWEI> debugging mpls ldp lsp error
