We want to add interface 40GE1/0/9 to Eth-trunk 1. As you can see below, the following error occurs.

[~CE-40GE1/0/9]eth-trunk 1
Error: The parameter of trunk command is invalid, because the trunk has added member of other port-type.
The error port is 40GE1/0/9.
[~CE-40GE1/0/9]

If we check the interface, we see that no configuration is under this interface.<?xml:namespace prefix = "o" />

[~CE-40GE1/0/9]dis this #
interface 40GE1/0/9 #
return

We check also Eth-trunk and no interface is added.
