Configuring The Delayed-Down-Time Interval - Extreme Networks PoS Installation And User Manual

5 Configure MPLS on the VLAN using the
command.
The following command example creates a VLAN named vlan1 and configures MPLSCP
on PoS port 8:1 on VLAN vlan1:
create vlan vlan1
config vlan vlan1 add ports 8:1
config vlan vlan1 ipaddress 192.168.100.1
config ppp bcp off ports 8:1
config ppp ipcp on ports 8:1
config mpls add vlan vlan1
For more information about MPLS and configuring MPLS, see the MPLS Installation and
User Guide.

Configuring the Delayed-Down-Time Interval

The delayed-down-time interval is the amount of time that PPP waits before declaring a
port down after a physical link failure has been detected. A non-zero value is useful
when recovery from the link failure is fast, for example, when APS is enabled on a
SONET port. In this case, APS may recover from the link failure before PPP responds,
thereby minimizing network down time. Generally, you should set a non-zero value for
the delayed-down-time interval any time APS is configured at either end of the link.
To configure the delayed-down-time interval for a specified PPP port, use the following
command:
config ppp delayed-down-time <seconds> ports <portlist>
The value of the
seconds. The default is 1 second.
A delayed-down-time interval of one second is usually sufficient to accommodate
APS line switches.
The following command example sets the delayed-down-time interval to 2 seconds for
port 1 of the PoS module installed in slot 8 of the BlackDiamond switch.
config ppp delayed-down-time 2 ports 8:1
