Redirect PVC Delay Time Enter a value between 0-255 seconds. This value
represents the number of seconds to wait before the
network initiates call clearing after a circuit goes down.
The default value is zero (0).
You configure this value only for the primary endpoint
and you can reset it at any time. A value of zero (0)
causes the network to initiate call clearing immediately,
which can trigger the switch over between a working
redirect PVC endpoint and its primary or secondary
endpoint. Increasing the value can minimize the PVC
redirection as a result of temporary DTE state changes.
For more information on redirect PVCs, see Chapter 10,
“Configuring ATM PVCs.”
Note: Changing the value for this attribute does not
admin down the logical port.
Resource Partitioning
Network Overflow
Set the Net Overflow parameters to one of two modes:
Public – (default) Enables the circuit to use public
trunks during traffic overflow or trunk failure
conditions.
Restricted – Restricts trunks to their own VPN.
See “Configuring a Logical Port for Layer 2 VPN” on
page 13-7 for more information.
Note: Changing the value for this attribute does not
admin down the logical port.
Backup Service Name Fault-tolerant PVC only – Select Yes to configure a
logical port for backup service. For more information,
see Chapter 14, “Configuring Fault-tolerant PVCs.”
Primary or Backup RLMI Port only – Select Yes to
configure this port as the Resilient Link Management
Interface (RLMI) backup port. Select No to configure
this port as the RLMI primary port.
Note: When a backup port is not in use, the port is idle
and does not use network resources.
For more information about RLMI, see Chapter 15,
“Configuring RLMI.”
