Command Forwarding Usage with a Virtual Chassis Configuration

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.

For example, to collect information about your system prior to contacting Juniper Networks Technical Assistance Center (JTAC), use the command request support information all-members to gather data for all the member switches. If you want to gather this data only for a particular member switch, use the command request support information member member-id .

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.

Table 1: Commands That Can be Run on All or Specific Members of the Virtual Chassis Configuration

Commands Available for Command Forwarding Purpose all-members member-member-id

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.

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.

request system reboot

Reboot JUNOS for EX-series software 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.

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.

request system storage cleanup

Free storage space on the switch by rotating log files and proposing a list of files for deletion. User input is required for file deletion.

Runs cleanup on all members of the Virtual Chassis configuration.

Displays information for the specified member switch.

show system boot-messages

Display initial messages generated by the system kernel upon startup. These messages are the contents of /var/run/dmesg.boot.

Displays information for all members of the Virtual Chassis configuration.

Displays information for the specified member switch.

Displays information for all members of the Virtual Chassis configuration.

Displays information for the specified member switch.

show system directory-usage

Display directory usage information.

Displays information for all members of the Virtual Chassis configuration.

Displays information for the specified member switch.

show system reboot

Display pending system reboots or halts.

Displays information for all members of the Virtual Chassis configuration.

Displays information for the specified member switch.

show system snapshot

Display information about the backup software that is located in the /altroot and /altconfig file systems. To back up software, use the request system snapshot command.

Display the JUNOS extensions loaded on your switch.

Displays information for all members of the Virtual Chassis configuration.

Displays information for the specified member switch.

show system statistics

Display systemwide protocol-related statistics.

Displays information for all members of the Virtual Chassis configuration.

Displays information for the specified member switch.

show system storage

Display statistics about the amount of free disk space in the switch's file systems.

Displays information for all members of the Virtual Chassis configuration.

Displays information for the specified member switch.

show system uptime

show system virtual-memory

Display the usage of JUNOS kernel memory, listed first by size of allocation and then by type of usage. Use show system virtual-memory for troubleshooting with JTAC.

Displays information for all members of the Virtual Chassis configuration.

Displays information for the specified member switch.

Table 2 shows a list of commands that are relevant only to the master. Do not use the options all-members or member-member-id with these commands.

Table 2: Commands Relevant Only to the Master

Commands Relevant Only to the Master Purpose

set date

Set the data and time.

show system buffers

Display information about the buffer pool that the Routing Engine uses for local traffic. Local traffic is the routing and management traffic that is exchanged between the Routing Engine and the Packet Forwarding Engine within the switch, as well as the routing and management traffic from IP (that is, from OSPF, BGP, SNMP, ping operations, and so on).

show system connections

Display information about the active IP sockets on the Routing Engine. Use this command to verify which servers are active on a system and which connections are currently in progress.
