3. Configuration Options

Table 3-32. Management PVC Options (2 of 6)

Payload Managed

Possible Settings: Enable, Disable

Default Setting: Disable

Specifies whether the PVC is payload managed.

Display Conditions – This is a read-only field set to Enabled if the PVC is IP Enabled.

Enable – The network PVC created will be monitored for the presence of IP frames containing the IP address specified in the Intf IP Address field. When such a frame is identified, it is extracted from the data stream and sent to the management stack.

Disable – A normal management PVC is created using the specified DLCI or EDLCI.

Intf IP Address

Possible Settings: Node-IP-Address, Special (nnn.nnn.nnn.nnn)

Default Setting: Node-IP-Address

Specifies the IP address needed to access the unit via this management PVC, providing connectivity to an external IP network through the frame relay network.

Node-IP-Address– Uses the IP address contained in the Node IP Address (see Table 3-31, Node IP Options).

Special (001.000.000.000 – 223.255.255.255) – Allows you to display/edit an IP address for the unit’s management PVC when the IP address for this interface is different from the node’s IP address.

Intf Subnet Mask

Possible Settings: Node-Subnet-Mask, Calculate, Special (nnn.nnn.nnn.nnn)

Default Setting: Node-Subnet-Mask

Specifies the subnet mask needed to access the unit when the management PVC is providing connectivity to an external IP network (through frame relay) that requires a specific subnet mask for the interface.

Node-Subnet-Mask– Uses the Interface IP Subnet contained in the Node-Subnet Mask configuration option (see Table 3-31, Node IP Options).

Calculate – Calculates the subnet mask created by the IP protocol based on the class of the IP address (Class A: 255.000.000.000, Class B: 255.255.000.000, or

Class C: 255.255.255.000). Cannot be displayed or edited.

Special (000.000.000.000 – 255.255.255.255) – Allows you to edit/display the subnet mask for the management PVC when the subnet mask is different for this interface. A text field displays where you can enter the subnet mask for this unit’s management PVC.

Set DE

Possible Settings: Enable, Disable

Default Setting: Disable

Specifies whether frames (packets) sent on a management PVC have the Discard Eligible (DE) bit set. This bit is used by the network to prioritize which frames to discard first during periods of network congestion. This allows management traffic to be viewed as lower priority than customer data.

Enable – Sets the DE bit to one on all frames sent on the management PVC.

Disable – Sets the DE bit to zero on all frames sent on the management PVC. This is the recommended setting, particularly for NSPs providing a managed network service.
