To specify APS, use the following syntax, enter the following command.
addapsln <workline> <workingslot> <protectionline> <protectionslot> <archmode>
Adding Connections on a PXM1 in a Stand-Alone Node
This section describes the CLI commands for provisioning connections on a PXM1 in a stand-alone
node. Connection addition conforms to the rules for a standard connection or a management connection.
(See the “Rules for Adding Connections” section on page 6-3”). In addition, this section describes the
commands for modifying specific features for a connection and policing connections by way of usage
parameter control (UPC).
The CLI commands correspond to functions in the Cisco WAN Manager application. The preferred CLI
command is addcon. (If the application requires NSAP addressing, enter addchan to add a connection
and cnfchan to modify a connection. To see the syntax for these two commands, refer to the command
reference.)
To add a connection in stand-alone node, perform the following steps on the PXM1.
Step 1 Enter the addcon command according to the following syntax:
addcon <port_num> <conn_type> <local_VPI> <local_VCI> <service> [CAC] [mastership]
[remoteConnId]
workline Line of the APS working line
workingslot Slot of the APS working line
protectionline Protection line
protectionslot Protection slot
archmode Identifies the type of APS operation. The GR-253 mode definitions include, 1+1 on
one back card, 1+1 on two back cards, 1:1, and Annex B
Currently, the only supported mode is 1+1 with two uplink cards (mode = 2). With
1+1 APS, both the working line and the protection line carry duplicate data even
though no error threshold has been exceeded or line break occurred. This mode
requires that two standard cables (rather than a Y-cable) connect at two ports on the
equipment at the opposite end. With the two-card implementation, workline must be
the same as protectionline.
port_num Logical port in the range 1–32 for a user connection or 34 for a management
connection
conn_type Number identifying the connection type—1 for VPC or 2 for VCC
local_VPI Local VPI in the range 0–4095
local_VCI Local VCI in the range 0–65535
