Command Forwarding Usage with EX Series and QFX Series Virtual Chassis

Some CLI commands can be run either on all members or on a specific member of a Virtual Chassis configuration. This functionality is referred to as command forwarding.

You can always specify that these commands be applied to all member switches in the Virtual Chassis by using the all-members option, or to a specific member switch by using the member-member-id option. If neither option is specified, the default command forwarding behavior, which varies by command, is used. See the Default row in Table 1 to learn the command forwarding behavior for a specific command.

For example, to collect information about a particular member switch prior to contacting Juniper Networks Technical Assistance Center (JTAC), use the request support information member member-id command to gather data for the specified member switch. If you want to gather this data for all member switches in the Virtual Chassis, you can enter the request support information command, which by default uses the all-members option, or the request support information all-members command.

Table 1 provides a list of commands that can be run either on all members of the Virtual Chassis configuration or on a specific member switch.

Default

request support information

Use this command when you contact JTAC about your component problem. This command is the equivalent of using the following CLI commands:

  • show version

  • show chassis firmware

  • show chassis hardware

  • show chassis environment

  • show interfaces extensive (for each configured interface)

  • show configuration (excluding any SECRET-DATA)

  • show system virtual-memory

Displays information for all members of the Virtual Chassis configuration.

Displays information for the specified member switch.

all-members

request system partition hard-disk

Set up the hard disk for partitioning. After this command is issued, the hard disk is partitioned the next time the system is rebooted. When the hard disk is partitioned, the contents of /altroot and /altconfig are saved and restored. All other data on the hard disk is at risk of being lost.

Partitions the hard disk on all members of the Virtual Chassis configuration.

Partitions the hard disk on the specified member switch.

all-members

request system reboot

Reboot Junos OS for EX Series or QFX Series switches after a software upgrade and occasionally to recover from an error condition.

Reboots all members of the Virtual Chassis configuration.

Reboots the specified member switch.

all-members

request system snapshot

Back up the currently running and active file system.

Backs up the file systems on all members of the Virtual Chassis configuration.

Backs up the file system on the specified member switch.

all-members

request system storage cleanup
