Alcatel-Lucent 7750 Configuration Manual page 521

The Ethernet tunnel will inherit the configuration from the first member port for these parameters. Addi-
tional member port that is added must have the same configuration.
The operator is allowed to update these port parameters only if the port is the sole member of an Ethernet
tunnel. This means that in the example below, the operator needs to remove port 1/1/4 and port 1/1/5 before
being allowed to modify 1/1/1 for the above parameters.
eth-tunnel 1
path 1
member 1/1/1
path 2
member 1/1/4
eth-tunnel 2
path 1
member 1/1/1
path 2
member 1/1/5
The no form of this command is used just to indicate that a member is not configured. The procedure
described above, based on the no path command must be used to un-configure/change the member port
assigned to the path.
Default no member
Parameters port-id — specifies the port-id associated with the path in the format x/y/z where x represents the IOM, y the
MDA and z the port numbers.
control-tag
Syntax control-tag vlan-id
no control-tag
Context config>eth-tunnel>path
Description
This command specifies the VLAN-ID to be used for Ethernet CFM and G.8031 control plane exchanges. If
the operator wants to replace an existing control-tag, the parent path needs to be in shutdown state, then
deleted and recreated before a new control-tag can be specified.
The no form of this command is used just to indicate that a control-tag is not configured. The procedure
described above, based on 'no path' command must be used to un-configure/change the control-tag assigned
to the path.
Default no control tag specified
Parameters vlan-id — specifies the value of the VLAN ID to be used for the control tag.
