Command Forwarding in a Virtual Chassis

You can run some CLI commands on all member routers, on the local member router, or on a specific member router in an MX Series Virtual Chassis configuration. This feature is referred to as command forwarding. With command forwarding, the router sends the command to the specified member router or routers, and displays the results as if the command were processed on the local router.

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 routers. If you want to gather this data only for a particular member router, use the command request support information member member-id.

Table 1 describes the commands that you can run on all (both) member routers (with the all-members option), on the local member router (with the local option), or on a specific member router (with the member member-id option) in an MX Series Virtual Chassis configuration, where member-id is 0 or 1.
