Field
The Keep Alive (KA) Error Threshold represents the number
of retries that the tunnel protocol attempts before bringing the
tunnel down. The retry interval is represented in seconds.
Enter a value between 3 and 255 seconds to define the KA
error threshold. The default is 5 seconds. Service is disrupted
if you modify this value once the tunnel is online.
For more information about this parameter, see
Threshold" on page
Specify one of the following options from the pull-down
menu to designate the type of traffic allowed on this tunnel:
Normal – (default) Tunnel can carry SVC, PVC, and network
management traffic, and OSPF address distribution.
Management Only – Tunnel can carry only network
management traffic, such as SNMP communication between
a switch and the NMS.
Management & User – Tunnel can carry PVCs and network
management traffic. This tunnel option does not support SVC
addressing information. If this is the only tunnel between two
nodes and you configure this option for it, then you
effectively prevent SVC traffic from traversing this tunnel.
Enter a value (from 1 - 65534) that defines the cost of using
this tunnel for a virtual circuit (VC) when a VC is being
dynamically created on the switch. The lower the
administrative cost of the path, the more likely OSPF will
select it for circuit traffic. The default administrative cost
value is 100.
Note: When you increase or decrease the administrative cost
of a tunnel, the reroute tuning parameters control the rate at
which the switch adds or removes circuits from the tunnel.
Modifying the value for this attribute does not bring down the
tunnel or the associated logical port.
Enter the area ID (x.x.x.x) for the destination area for this
endpoint. The range of available values is from 0.0.0.0 to
255.255.255.255. Area 0.0.0.0 is the network backbone area.
Area 0.0.0.1 is Area 1.
For a detailed description of OSPF areas, and how to use IP to
configure multiple OSPF areas, see the IP Services
Configuration Guide for CBX 3500, CBX 500, and
B-STDX 9000.
Notes: Modifying the value for this attribute does not bring
down the trunk or the associated logical port.
Area 1 is reserved for Lucent switches.
