Monitoring ANCP

You can display ANCP information with the following commands.

show adjustment-factor

Use to display the configured values for the adjustment factor applied to the upstream data rate and downstream data rate reported by ANCP for each DSL type. The adjustment factor is used to generate an accurate QoS shaping rate.
Field descriptions
- L2C QoS Adjustment Rates—List of all DSL types and the corresponding adjustment factor for each
- ADSL1—Adjustment factor for the ADSL1 DSL type
- ADSL2—Adjustment factor for the ADSL2 DSL type
- ADSL2+—Adjustment factor for the ADSL2+ DSL type
- VDSL—Adjustment factor for the VDSL DSL type
- VDSL2—Adjustment factor for the VDSL2 DSL type
- SDS—Adjustment factor for the SDS DSL type

Example 1—Displays the adjustment factor for each DSL type

host1#show adjustment-factor
  L2C QoS Adjustment Rates:
  ADSL1:  45
  ADSL2:  55
  ADSL2+: 100
  VDSL:   100
  VDSL2:  55
  SDS:    100

Example 2—Displays the adjustment factor for a specific DSL type verification criteria
```
host1#show adjustment-factor vdsl2
  VDSL2:11
```
See show adjustment-factor.

show l2c

Use to display information about the ANCP configuration on the router.
Field descriptions
- Current timeout—Configured session timeout (in seconds)
- Qos adaptive mode—Whether QoS adaptive mode is enabled (true) or disabled (false)
- Wait-for-gsmp-syn—Whether learning is enabled or disabled
- gsmp-syn-timeout—Configured TCP session timeout (in seconds)

Example

host1#show l2c
L2C:
  Current session timeout: 25 seconds
  Qos adaptive mode: false
  Wait-for-gsmp-syn: Enable 
  gsmp-syn-timeout: 18 seconds

show l2c discovery-table
