Field Name

Field Description


Maximum physical bandwidth in Kbps; line rate

IP/MPLS reserveable bw

Total bandwidth in Kbps that can be reserved for MPLS; includes bandwidth that is already reserved as well as bandwidth not yet reserved

current total available bw

Total bandwidth in Kbps that is available to be reserved

MPLS TE flooding threshold up/down

Absolute percentages of total reservable bandwidth that trigger the flooding of the new bandwidth value throughout the network; flooding is triggered when bandwidth increases past any of the up threshold values and when bandwidth decreases past any of the down threshold values

MPLS TE administrative weight

Weight assigned to the interface that supersedes a weight assigned by the IGP

MPLS TE attribute flags

32-bit value that assigns the interface to a resource class and enables a tunnel to discriminate among interfaces by matching against tunnel affinity bits

Available BW at 8 priority levels

Bandwidth in Kbps that is available at each priority level in the range 0–7
