A link is present for the end operating at 10 Mbps, but the physical layer LED (for example, the
Active LED) keeps flashing, and the port cannot transmit or receive traffic correctly.
Solution
To resolve the issue:
1.
Change the rate and duplex mode of a port by force to make sure the rate and duplex mode of
the local end are the same as the peer end.
For the copper FE ports and GE ports, both the rate and duplex mode are auto-negotiated by
default.

If the issue persists, contact H3C Support.
