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
