1. Click Service > MPLS TE Manager from the tabular navigation system on the top of the IMC main
page.
2. Click Resource Mng > Interface Mng in the left navigation tree.
3. In the Interface List section of the page, click the Operation icon on the same line as the
interface that you want to view bandwidth about. A list of options appears.
4. Select the Query Available Bandwidth option to view all available bandwidth.
5. To return to the previous screen, click Back.
Configuring interface traffic parameters
To configure traffic parameters for an interface:
1. Click Service > MPLS TE Manager from the tabular navigation system on the top of the IMC main
page.
2. Click Resource Mng > Interface Mng in the left navigation tree.
3. In the Interface List section of the page, click the Operation icon on the same line as the
interface that you want to configure interface traffic parameters for. A list of options appears.
4. Select the Configure Interface Traffic Parameters option.
5. In the Configure Interface Traffic Parameters page, enter information in the IGP flood upper limit of
bandwidth diversification (%) field and IGP flood lower limit of bandwidth diversification (%) field
to configure the upper and lower thresholds for IGP to flood bandwidth changes, and enter
information in the TE Metric of a Link field to assign TE metric to the link. The valid range of IGP
flood upper limit of bandwidth diversification and IGP flood lower limit of bandwidth
diversification is 0 to 100 and the default value is 10. The valid range of TE metric of a link is from
0 to 4294967295, and the default value is 0.
IGP flooding—After the bandwidth of links regulated by MPLS TE changes, CSPF may need to
recalculate paths. This tends to be resource consuming as recalculation involves IGP flooding. To
reduce recalculations and flood only significant changes, you may configure the following two IGP
flooding thresholds in percentages so that IGP flooding is triggered only when the thresholds are
reached:
• IGP flood upper limit of bandwidth diversification (%)—When the percentage of
available-bandwidth increase to the maximum reservable bandwidth exceeds the threshold,
the change is flooded.
• IGP flood lower limit of bandwidth diversification (%)—When the percentage of
available-bandwidth decrease to the maximum reservable bandwidth exceeds the threshold,
the change is flooded.
6. Click OK.
Enabling interfaces
With this function, you can enable MPLS TE on a disabled interface.
