Step 1
| Complete the
NTP-J22 Log into CTC
procedure at a node where you want to create a pseudowire.
|
Step 2
| From the View
menu, choose
Go to
Network View.
|
Step 3
| Click the
Layer2+ tab.
|
Step 4
| From the left
pane, click
Circuits.
|
Step 5
| Click the
Pseudowire tab.
|
Step 6
| Click
Create. The Circuit Creation wizard appears.
|
Step 7
| In the AC Global
Attributes area of the Circuit Attributes screen, specify the global attributes
as follows:
- Enter the name
of the pseudowire that you want to create in the PW Name field.
- Enter the
description of the pseudowire in the PW Description field.
- From the Admin
State drop-down list, choose
UP or
DOWN.
The default value is UP.
- Enter the
bandwidth value in Kbps, Mbps (default), or Gbps in the Bandwidth field.
The
specified bandwidth is checked against the available bandwidth on the tunnel
and the AC ports. If the specified bandwidth exceeds the available bandwidth on
the tunnel or the AC ports, an error message is displayed.
Note
| The
specified bandwidth is used only for accounting purposes when the core has a
MPLS–TE or MPLS–TP tunnel. The specified bandwidth is not reserved by the CPT
system for the actual traffic nor is it enforced on services. For example, if
the actual traffic exceeds the bandwidth value, the CPT system carries the
traffic and does not raise an alarm.
|
- Enter the
VPN ID in the VPN ID field.
|
Step 8
| In the Redundancy
area of the Circuit Attributes screen, specify the following to create a
redundant pseudowire:
- Check the
Enabled check box to enable pseudowire redundancy.
- Check the
Dual
Homed Peer check box to create a special case of pseudowire
protection. In this case, there is an additional end point (T-PE3) for the
pseudowire apart from T-PE1 and T-PE2.
- Check the
Provision working go & return on primary path
check box to enable the user to configure working go and return path of a
pseudowire on primary path. For example, if this checkbox is unchecked, a
pseudowire A is primary pseudowire and pseudowire B is backup pseudowire on
T-PE1 node, pseudowire A must be backup pseudowire and pseudowire B must be
primary pseudowire on T-PE2 node.
- Enter the
delay timer in seconds in the Enable Delay field to specify how long the backup
pseudowire must wait to take over after the primary pseudowire goes down. The
range is from 0 to 180 seconds.
- Enter the
delay timer in seconds in the Disable Delay field to specify how long the
primary pseudowire must wait after it becomes active to take over from the
backup pseudowire. The range is from 0 to 180 seconds.
- Click the
Never radio button to specify that the primary
pseudowire never takes over from the backup pseudowire.
- Click
Next.
The T-PE1
screen appears. Terminating Provider Edge (T-PE1) represents one of the end
points of the pseudowire.
|
Step 9
| To choose a non
CPT source
node for the pseudowire, complete the following steps:
- Check the
Unmanaged
Node check box.
At least one
node (T-PE or S-PE node) in the pseudowire must be a
CPT
node. The other nodes can be unmanaged nodes.
- Enter the
router IP address in the Router ID field.
- Enter the VC
ID in the VC ID field.
|
Step 10
| To choose a
CPT source
node for the pseudowire, choose the
CPT node
from the Node drop-down list. The Router ID field is automatically populated.
Note
| If a VPWS is
provisioned between two nodes where one node is running CPT version 9.7.0.2 and
the other node is running older version. Before provisioning the pseudowire,
set the TDM SFP labels to the default value.
|
|
Step 11
| In the AC End
Point area of the T-PE1 screen, identify the attachment circuit (AC) with the
exact end point of the
CPT node
as follows:
The attachment
circuit is the physical or virtual circuit attaching a CE to a PE.
- If you want to
choose a port
or CPT 50 to serve as an
end point for the pseudowire, complete the following:
-
Check
the RING ID check box.
Note
| This check box is enabled only if the service state of the ring
is enabled.
|
-
From the
RING ID drop-down list, choose a ring.
Note
| This
drop down list is enabled only if the RING ID check box is checked.
|
-
From the
Slot/CPT 50 drop-down list, choose a slot
or CPT 50.
Note
| If you select the RING ID
check box, a list of available CPT 50 is displayed. Otherwise, a list of
available ports is displayed.
|
-
From the
Port drop-down list, choose a port.
- If you want to
choose a channel group to serve as an end point for the pseudowire, complete
the following:
-
Check
the
CHGRP check box.
-
From the
CHGRP drop-down list, choose a channel group to serve as an end point.
-
Click
Manual
Load Balancing to configure manual load balancing on the ports of the
channel group.
The
Manual Load Balancing dialog box appears.
-
From the
Primary Loadbalanced Link list, choose a port.
-
Click

class drop-down list, choose a pseudowire class.
- Enter the VC
ID used by the pseudowire in the VC ID field.
- Check the
Static check box to specify that the pseudowire

dynamic.
- (For static
pseudowire segment) Enter an unused static label in the Local Label field.
|
Step 14
| In the Backup PW

- From the PW
class drop-down list, choose a PW class for the backup pseudowire.
- Enter the VC
ID used by the backup pseudowire in the VC ID field.

- Click
Next.
The T-PE2
screen appears. T-PE2 represents one of the end points of the pseudowire.
|
Step 15
| From the Node
drop-down list, choose the destination node for the pseudowire.
You can choose a
CPT or
non
CPT node
as the destination node similar to the source node.
|
Step 16
| Specify all the
values in the T-PE2 screen similar to the previous T-PE1 screen.
|
Step 17
| If you had
checked the
Dual
Homed Peer check box in the Circuit Attributes screen, an
additional screen appears to specify the settings for T-PE3.
|
Step 18
| Click
Next.
The PW Protected
Circuit Path screen appears.
|
Step 19
| In the PW
Protected Circuit Path screen, specify the following for Switch Provider Edge
(SPE) nodes to create a multisegment pseudowire.
Note
| Do not set
the pseudowire class with the interworking at SPE nodes while creating a
multisegment pseudowire. Setting this would corrupt the Label table.
|
- Click the
SPEs
Working tab.
- Select a
node from the network map and click
Add. The
Add node dialog box appears.
- From the
Node drop-down list, choose a node and click
Apply.
- Enter the
Neighbor ID and VC ID in the respective fields.
- From the PW
class drop-down list, choose a pseudowire class.

MTU, Requested VLAN, Interface Description, and VCCV Flags in the respective
fields and click
OK. You
can specify a value from 64 to 9600 for MTU. The default value is 1500.
The MTU and
Interface Description fields are applicable to dynamic segments. The Requested
VLAN field is applicable to the static segment.
Note
| The MTU
of a pseudowire can not be greater than the MTU of the LAG on which this
pseudowire is configured.
|
|
Step 20
| Click the
SPEs Backup
tab and specify all the values similar to the
SPEs Working
tab.
|
Step 21
| Click
Finish to create a pseudowire.
Note
| You cannot
create a pseudowire successfully, if the TDM pluggable is already configured on
the port and the pseudowire class has any of these configurations:
-
TP as
tunnel type
-
Sequencing
enabled
-
BFD over
VCCV enabled
-
LDP as
protocol
-
Status OAM
enabled
|
Note
| In scaled
configuration, if shut or no shut operation performed on the core ports that
have huge number of pseudowires configured, the CPT 50 may reboot due to high
CPU utilization.

Step 22
| Return to your
originating procedure (NTP).
