Dense Wavelength Division Multiplexing Commands on the Cisco ASR 9000 Series Router
admin-state
To configure the transport administration state on a DWDM port, use the admin-state command in DWDM
configuration mode. To return the administration state from a DWDM port to the default, use the no form of
this command.
admin-state {in-service| out-of-service}
no admin-state {in-service| out-of-service}

Syntax Description
Command Default
Command Modes
Command History
Usage Guidelines
Places the DWDM port in In Service (IS) state, to support all normal operation.in-service
out-of-service
Out-of-service is the default transport administration state.

When you configure admin-state out-of-service, the DWDM port is placed in OOS state. The laser is turned
off, traffic flow is stopped, and proactive protection is disabled. However, configuration changes can still be
made on the port.
Places the DWDM port in Out of Service (OOS) state. The laser is turned off

The DWDM controller supports two loopback operation modes for diagnostic purposes: internal and line.
The terminal (internal) loopback mode allows the received data from the Layer 2 Framer (for example, a
SONET/SDH framer for POS or Ethernet MAC for 10GE) of the PLIM to be looped back to the ingress side
of the Framer. This allows the packets to be looped back to the PLIM. The line loopback mode allows the

for line diagnostics.

Note
Note
Before Cisco IOS XR Software Release 4.2.0, only transport-mode wan was used under the interface
configuration mode to set WAN PHY controller. Then, both Operational Mode and Configuration Mode
would be changed to WAN Mode.
After Cisco IOS XR Software Release 4.2.0, you can use transport-mode wan under the interface
configuration mode to use basic function of WAN PHY. In addition, we can use wanmode on under the
wanphy controller mode to use alarm function and BIP counter.
On the Cisco A9K-4T16GE-TR and Cisco A9K-4T16GE-SE line cards, mixed use of LAN and WAN
transport modes is not supported due to hardware limitation. In other words, WAN PHY is configured on
all the four 10GigE ports to be operated either in LAN mode or WAN mode for 10 GigE ports 16, 17, 18
and 19.
On applying the configuration change from LAN to WAN or back on port 16, the same configuration
shall be applied on all the other 10 GigE ports 17, 18, and 19. The ports 17, 18 or 19 cannot be used to
make configuration changes using the transport-mode command. Also, the running configuration shows
the configuration change only on port 16.

for assistance.
You can set the wavelength to a specific ITU channel, that is represented by a channel number in the Multi

The spacing between wavelengths is 50 GHZ or 100 GHz. Use the show controllers dwdm command with
the wavelength-map keyword to view the channel numbers and wavelengths that are supported for a particular

carrier-delay
To delay the processing of hardware link down notifications, use the carrier-delay command in interface
configuration mode.
carrier-delay
Note
Syntax Description
The carrier-delay command is active only when both up and down are configured from the host.
•
If this configuration is not used, the default value is determined by the underlying driver, and may
•
vary depending on whether auto-negotiation is enabled. The default value is chosen to provide enough
time for the hardware link to stabilize after state change and to protect the system from excessive
link flaps.
If a value of 0 is set, carrier-delay is disabled in that direction.
•
The range of carrier-delay on access port of ASR 9000v is 1 to 60000 msec. If a value of 0 is set,
•
the default value of 100 msec is applied. A value greater than 60000 msec will be ignored and show
interfaces output will display the previously configured msec.
Both up and down must be set to the same value. If the values are different, the smaller value will
•
be set for both up and down configuration.
carrier-delay {down milliseconds [up milliseconds]| up milliseconds [down milliseconds]}
down milliseconds
up milliseconds
Length of time, in milliseconds, to delay the processing of hardware link down
notifications. Range is from 0 through 2147483648.

Usage Guidelines
Note
Task ID
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
When you delay the processing of hardware link down notifications, the higher layer routing protocols are
unaware of a link until that link is stable.
If the carrier-delay down milliseconds command is configured on a physical link that fails and cannot be
recovered, link down detection is increased, and it may take longer for the routing protocols to re-route traffic
around the failed link.
In the case of very small interface state flaps, running the carrier-delay down milliseconds command prevents
the routing protocols from experiencing a route flap.
Enter the show interface command to see the current state of the carrier-delay operation for an interface.
No carrier-delay information is displayed if carrier-delay has not been configured on an interface.
