Port Loopback Commands
Port Loopback Commands
loopback-no-svc-port
Syntax [ no ] loopback-no-svc-port {mirror | mac-swap | testhead} port-id
Context config>system
Description
This command specifies the port to assign for system use when using port loopback with mac-swap OAM
tool or for the mirroring OAM tool or for the testhead application. The system utilizes the resources of the
port and the port is not available for configuring services.
The user cannot share a single port between both these tools/applications, if they intend to use the tools
simultaneously. The system displays an error if the user tries to configure the same port for use with multiple
OAM tools OR if the user tries to use the tool without first configuring the port resources to be used by the
tool.
The user will have to execute the command multiple times, once for each OAM tool with a different port ID,
if they intend to use these tools simultaneously. Example: user can dedicate two ports for use, by executing
the command loopback-no-svc-port mirror 1/1/1 for use with mirroring, followed by execution of the
command loopback-no-svc-port mac-swap 1/1/2 again, for mac-swap OAM tool.
The user can dedicate two ports for use, by executing the command loopback-no-svc-port testhead 1/1/1 for
use with testhead, followed by execution of the command loopback-no-svc-port mac-swap 1/1/2 again, for
mac-swap OAM tool. For more information, see the platform specific note at the end of this CLI description.
The system verifies if any services are configured on the port specified with this command and if services
are configured the command fails.
The no form of the command disables the use of this port by the specified OAM tool.
NOTE:
• On 7210 SAS-X, this command must be used to dedicate as many front-panel ports as necessary, if they
intend to use all the OAM tools simultaneously. A maximum of up to 3 front-panel ports is needed when
all the OAM tools are used simultaneously. There are no internal virtual port resources available for use.
• On 7210 SAS-M 24F 2XFP (ETR and non-ETR variants), user can use one of the ports configured
under the BOF parameter no-service-ports, for use with either mac-swap or mirroring or testhead OAM
tool. If user intends to use the OAM tools simultaneously, then additional front-panel ports need to be
configured for use with one of the tools.
• On 7210 SAS-M 24F, user can use the internal port 1/1/25 for use with either mac-swap or mirroring
OAM tool. If user intends to use the OAM tools simultaneously, then additional front-panel ports need
to be configured for use with one of the tools.
• On 7210 SAS-T, user can use the 2 available internal ports (that is, port 1/1/27 and 1/1/28) for use with
either mac-swap or mirroring or testhead OAM tool. If user intends to use all the OAM tools simultane-
ously, then additional front-panel ports need to be configured for use with one of the tools.
• On 7210 SAS-R6, user has a fixed number of internal ports for use with OAM tools (such as testhead
OAM tool, mac-swap OAM tool and Dot1q/remote mirroring OAM tool) that need the resources of
