# Monitoring Interfaces Configured with Traffic Engineering Bandwidth Accounting

#### Purpose

Display interfaces on which traffic engineering bandwidth accounting is configured.

#### Action

To display information about CAC interfaces:

    host1#show cac interface
    atm2/0
      bandwidth 10 kbps
      IP/MPLS reserveable bw 10 kbps
      current total available bw 10 kbps
      MPLS TE flooding threshold:
        up   15 30 45 60 75 80 85 90 95 96 97 98 99 100
        down 100 99 98 97 96 95 90 85 80 75 60 45 30 15
      MPLS TE administrative weight 0
      MPLS TE attribute flags 0
      Available BW at 8 priority levels:
          0     10 kbps
          1     10 kbps
          2     10 kbps
          3     10 kbps
          4     10 kbps
          5     10 kbps
          6     10 kbps
          7     10 kbps

#### Meaning

Table 61 lists the show cac interfacevc command output fields.

Table 61: show cac interface Output Fields

Field Name | Field Description
--- | ---
bandwidth | 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
