When the lossy mode and the outward-facing 802,1ag function are both configured for an interface, the outward-facing 802,1ag function fails.

Do not configure the lossy mode and the outward-facing 802,1ag function for the same interface.

When the lossy mode and the outward-facing 802,1ag function are both configured for an interface, the outward-facing 802,1ag function fails.

If the client end supports hardware-based packet sending, the board that sends packets must support 1588v2 clock synchronization.

Select a board that supports 1588v2 clock synchronization for packet sending.

Hardware-based packet sending measurement results obtained during a jitter test are inaccurate.

If the server end supports hardware-based packet reply, the board that replies packets must support 1588v2 clock synchronization.

Select a board that supports 1588v2 clock synchronization for packet reply.

Hardware-based packet sending measurement results obtained during a jitter test are inaccurate.

If a destination IP address is configured for the client end, the outbound interface of a route cannot be any management interface.

Do not deploy any test instance for which the outbound interface of a route is a management interface.

Hardware-based packet sending measurement results obtained during a jitter test are inaccurate.

The MTU of the tested link cannot be less than 64,

Configure the MTU of the tested link to be no less than 64,

Jitter measurement results are inaccurate.

One-way delay measurement requires the deployment of 1588v2 clock synchronization.

To measure one-way delay, deploy 1588v2 clock synchronization.

Hardware-based packet sending measurement results obtained during a jitter test are inaccurate.

The commands of ICMP ping and NQA tests do not save the configuration file. Therefore, the new plane does not deliver any configuration during the ISSU. If you run an ICMP ping or NQA test during the ISSU, the test fails. You can run the test command again after the ISSU is complete.

N/A

Running a ping or NQA test fails during an ISSU.

Only one VXLAN segment can be detected. End-to-end detection is not supported in scenarios where multi VXLAN segments are combined.

None

Only one VXLAN segment can be detected.

If a static route is associated with NQA and the path tested by NQA also depends on the static route, only direct connection is supported.

None

The static route fails to be restored.

In a cross-domain or private L3VPN detection scenario where a P node does not have any return route but supports MPLS forwarding, when the tracert ipv4 command is run to test an MPLS tunnel, the display of cross-domain P node information depends on whether the associated board supports tracert fast reply.

None

When the tracert ipv4 command is run to test an MPLS tunnel in a cross-domain sceNonerio, information about cross-domain P nodes fails to be displayed if the associated board does not support tracert fast reply.

When the tracert lsp command is run to test an LSP , cross-domain P nodes are not supported.

None

After the tracert lsp command is run, timeout is displayed for cross-domain P nodes.

The tracert test skips cross-domain P nodes.

L2VPN PW ping/tracert can test a PW with only one segment, not a PW with multiple segments.

None

L2VPN PW ping/tracert can test a PW with only one segment, not a PW with multiple segments.

When testing VPLS or VLL PWs with tunnel overlapping, L2VPN PW ping/tracert can test only the outer backup plane.

None

When testing VPLS or VLL PWs with tunnel overlapping, L2VPN PW ping/tracert can test only the outer backup plane.

Ping function for BASE user access in CU separation scenarios:

1. If the NE functions as the initiator, a ping operation can be initiated on the CP only.

2. If the NE functions as the response end, only fast reply scenarios are supported. In this case, you must enable the fast reply function on the VNE by running the icmp-reply fast command.

None

1. An error is reported if the UP initiates a ping test.

2. If the response end does not support fast reply, request packets will be discarded.

The server and client of an ICMP jitter, UDP jitter, or TCP test instance must be VRP-based devices. The test result depends on the board hardware capability.

None

The test fails or is inaccurate.
