Configuring Aggregated SONET/SDH Interfaces

 

Configuring Aggregated SONET/SDH Interfaces

To configure the aggregated SONET/SDH interfaces, perform the following tasks:

  1. Configuring Device Count

  2. Configuring Constituent Physical Interface

  3. Configuring an Aggregated SONET/SDH Interfaces

  4. Displaying the Aggregated SONET/SDH Interface Configuration

Configuring Device Count

To configure the number of aggregated SONET/SDH interfaces as per requirement.

  1. In configuration mode, go to the [edit chassis aggregated-devices sonet] hierarchy level.
  2. Configure the number of aggregated SONET interfaces from 1 through 64.

For example, if you set the device-count statement as 12, you can configure the aggregated SONET/SDH interfaces from as0 through as11.

Configuring Constituent Physical Interface

After you set the device count at the [edit chassis aggregated-devices sonet] hierarchy level, you can associate a physical interface with an aggregated SONET/SDH interface.

To associate the physical interface with an aggregated SONET/SDH link.

  1. In configuration mode, go to the [edit interfaces interface-name sonet-options] hierarchy level. For example, set the interface name as so-1/3/0.
  2. Configure the aggregate statement with the aggregated interface to join a SONET aggregate.
Note

x is the interface instance number and can be from 0 through 63, for a total of 64 aggregated interfaces. You should not mix SONET and SDH mode on the same aggregated interface.

You can optionally specify other physical properties that apply specifically to the aggregated SONET/SDH interface; for details, see SONET/SDH Interfaces Overview.

Configuring an Aggregated SONET/SDH Interfaces

To configure an aggregated SONET/SDH interface, for example as0 interface.

  1. In configuration mode, go to the [edit interfaces as0 aggregated-sonet-options] hierarchy level.
  2. Configure the aggregated links speed of the as0 interface as mixed, oc12, oc192, oc3, oc48, or oc768.

    You can set the required link speed for all interfaces included in the bundle, or specify that the bundle contains interfaces with mixed interface speeds.

    Note

    For nonconcatenated interfaces on aggregated SONET/SDH interfaces, you can configure the link speed of the aggregate to match the speed of the nonconcatenated interface. For example, an OC12 PIC can have nonconcatenated interfaces with a link speed of OC3.

  3. Configure the minimum bandwidth necessary to sustain the bundle in bits per second (bps).
  4. Configure the minimum number of aggregated links that must be up for the bundle as a whole to be labeled up on the ae0 interface from 1 through 32. By default, only one link must be up for the bundle to be labeled up

On a T Series, TX Matrix router with SONET interfaces, the valid range for minimum-links number is from 1 through 16. When the maximum value (16) is specified, all configured links of a bundle must be up for the bundle to be labeled up.

On all other router routers, the range of valid values for minimum-links number is 1 through 8 and the maximum number of links supported in an aggregate is eight. When the maximum value (8) is specified, all configured links of a bundle must be up for the bundle to be labeled up.

Displaying the Aggregated SONET/SDH Interface Configuration

Purpose

To display the aggregated SONET/SDH configuration for the as0 interface when the following options are set to get an aggregated SONET/SDH interface up and running:

  • Minimum links—1

  • Link speed—oc3

  • Device count—15

  • SONET interface name—so-1/3/0

Action

Run the show command after setting the aforementioned parameters.

Deleting an Aggregated SONET/SDH Interface

To delete an aggregated SONET/SDH interface (for example as0 interface) and to set the aggregated SONET/SDH interface to down state, perform the following tasks:

  1. Deleting the Interface

  2. Deleting Device Count

Deleting the Interface

To delete an aggregated SONET/SDH interface, for example the as0 interface.

  1. In configuration mode, go to the [edit interfaces] hierarchy level.
  2. Delete the aggregated SONET/SDH interface.

To set the aggregated SONET/SDH interface to down state

  1. In configuration mode, go to the [edit chassis aggregated-devices sonet] hierarchy level.
  2. Delete the aggregated SONET/SDH interface.

Deleting Device Count

To delete the device count for the aggregated SONET/SDH interfaces.

To set the aggregated SONET/SDH interface to down state

  1. In configuration mode, go to the [edit chassis aggregated-devices sonet] hierarchy level.
  2. Delete the aggregated SONET/SDH interface.

Configuring Filtering on a Aggregated SONET/SDH Interface

  1. Configuring Filters or Sampling on Aggregated SONET/SDH Links

  2. Configuring Filter Options

Configuring Filters or Sampling on Aggregated SONET/SDH Links

To set up firewall filters or sampling on the aggregated SONET/SDH interfaces, you must configure the asx interface with the following properties.

  1. In configuration mode, go to the [edit interfaces asx unit logical-unit-number filter] hierarchy level.
  2. Configure the input option with a name for the filter to be applied to received packets.
  3. Configure the output option with a name for the filter to be applied to transmitted packets.

Configuring Filter Options

To configure firewall filters options for input filter input-filter-name and output filter output-filter-name..

  1. In configuration mode, go to the [edit firewall] hierarchy level.
  2. Configure the input filter.
  3. Configure the input filter options.
  4. Configure the output filter.
  5. Configure the output filter options.

Configuring Sampling on Aggregated SONET/SDH Interfaces

  1. Configuring Sampling on a Aggregated SONET/SDH Interface

  2. Configuring Sampling Filter Options

  3. Configuring Forwarding Options For a Sampling Filter

Configuring Sampling on a Aggregated SONET/SDH Interface

To set up sampling on the aggregated SONET/SDH interfaces, you must configure the asx interface with the following properties.

  1. In configuration mode, go to the [edit interfaces asx unit logical-unit-number filter] hierarchy level.
  2. Configure the input option with a name for the filter to be applied to received packets.

Configuring Sampling Filter Options

To configure firewall sampling filters options for input sampling filter input-sampler-name.

  1. In configuration mode, go to the [edit firewall] hierarchy level.
  2. Configure the input filter.
  3. Configure the input filter options.

Configuring Forwarding Options For a Sampling Filter

To configure the forwarding optons for a sampling filter.

  1. In configuration mode, go to the [edit forwarding-options sampling input] hierarchy level.
  2. Configure the ratio of packets to be sampled (1 out of N number of packets) from 1 through 65535.
  3. Configure the number of samples after initial trigger from 0 through 20.
  4. Configure the threshold of samples per second before dropping.
  5. Configure the maximum length of the sampled packet from 0 through 9192 bytes.
