Interfaces
single-fiber
Syntax [no] single-fiber
Context config>port>ethernet
config>port>sonet-sdh
Description This command enables packet gathering and redirection of IP packets from a single fiber (RX) port of the
Ethernet or SONET/SDH interface and redistributes packets to other interfaces through either static routes
or policy-based forwarding.
This parameter can be applied in conjunction with the strip-label command. If they are applied together, the
port must have the single-fiber option configured before it can be associated with an interface that is config-
ured with the strip-label option.
Once a port is configured with single-fiber, traffic will no longer be transmitted out of that port. This com-
mand can be used in conjunction with strip-label.
Default no single-fiber
