Release Information

Statement introduced before Junos OS Release 7.4.

Description

Create a configuration group.

Options

group-nameName of the configuration group. To configure multiple groups, specify more than one group name.
configuration-dataThe configuration statements that are to be applied elsewhere in the configuration with the apply-groups statement, to have the target configuration inherit the statements in the group.
whenDefine conditions under which the configuration group should be applied. Conditions include the type of chassis, model, or Routing Engine, virtual chassis member, cluster node, and start and optional end time of day. If you specify multiple conditions in a single configuration group, all conditions must be met before the configuration group is applied.
  • chassis chassis-id—Specify the chassis type of the router. Valid types include SCC0, SCC1, LCC0, LCC1 ... LCC3.

  • member member-id—Specify the name of the member of the virtual chassis.

  • model model-id—Specify the model name of the router, such as m7i or tx100.

  • node node-id—Specify the cluster node.

  • peers names-of-peers—Specify the names of the MC-LAG peers participating in commit synchronization.

  • routing-engine routing-engine-id—Specify the type of Routing Engine, re0 or re1.

  • time start-time [to end-time]—Specify the start time or time duration for this configuration group to be applied. If only the start time is specified, the configuration group is applied at the specified time and remains in effect until the time is changed. If the end time is specified, then on each day, the applied configuration group is started and stopped at the specified times. The syntax for specifying the time uses the format yyyy-mm-dd.hh:mm, hh:mm, or hh.

conditional-dataOption introduced in Junos 11.3. The conditional statements that are to be applied when this configuration group is applied. On routers that support multiple Routing Engines, you can also specify two special group names:
  • re0—Configuration statements that are to be applied to the Routing Engine in slot 0.

  • re1—Configuration statements that are to be applied to the Routing Engine in slot 1.

On routers that support multiple Routing Engines, you can also specify two special group names:

The configuration specified in group re0 is applied only if the current Routing Engine is in slot 0; likewise, the configuration specified in group re1 is applied only if the current Routing Engine is in slot 1. Therefore, both Routing Engines can use the same configuration file, each using only the configuration statements that apply to it. Each re0 or re1 group contains at a minimum the configuration for the hostname and the management interface (fxp0). If each Routing Engine uses a different management interface, the group also should contain the configuration for the backup router and static routes.

(Routing matrix only) The TX Matrix router supports group names for the Routing Engines in each connected T640 router in the following formats:

Note

The management Ethernet interface used for the TX Matrix Plus router, T1600 routers in a routing matrix, and PTX Series Packet Transport Routers, is em0. Junos OS automatically creates the router’s management Ethernet interface, em0.

  • lccn-re0—Configuration statements applied to the Routing Engine in slot 0 of the specified T640 router that is connected to a TX Matrix router.

  • lccn-re1—Configuration statements applied to the specified to the Routing Engine in slot 1 of the specified T640 router that is connected to a TX Matrix router.

    n identifies the T640 router and can be from 0 through 3.

Required Privilege Level

configure—To enter configuration mode.
