Managing OmniSwitch 6400 Series Stacks Reloading Switches Reloading Switches Reloading is essentially a soft boot of a switch. Users can reload stacked modules operating in any role- i.e., primary, secondary, idle, and pass-through. Refer to the sections below for more information. Reloading the Primary Management Module If the switch with the primary management role is reloaded, the switch with the secondary role automatically takes over primary management functions. In other words, the switch with the secondary role assumes the primary role as soon as the reload is initiated. Meanwhile, the idle switch with the next lowest slot number automatically assumes the secondary role. When the reloaded switch (the former primary module) comes back up, it assumes an idle role within the stack. To reload the primary management module, use the reload command. The optional syntax primary can be used in the command line, but is not required. For example: -> reload primary Note. A primary management module reload can also be scheduled for a later time or date. For information on scheduling a primary module reload, as well as additional command details, refer to the OmniSwitch CLI Reference Guide. Primary - Slot 1 Secondary - Slot 2 Idle - Slot 3 Idle - Slot 4 1 In this stack of four OmniSwitch 6400 Series switches, the slot 1 switch is the primary management module. The slot 2 switch is the secondary. Slots 3 and 4 are operating in idle roles. -> reload primary 2 The user reloads the stack's primary management module by issu- ing the reload primary command. Any data flow on the primary switch's Ethernet is interrupted. Booting... Primary - Slot 2 Secondary - Slot 3 Idle - Slot 4 Idle - Slot 1 Primary - Slot 2 Secondary - Slot 3 Idle - Slot 4 3 The secondary switch automatically takes over the primary role. The idle switch with the next-lowest slot number-in this case, slot 3-automatically becomes the secondary management module. The slot 4 switch remains unaffected. In addition, Ethernet traffic on slots 2, 3, and 4 remains unaffected. 4 When the rebooted switch comes back up, it assumes an idle role within the stack.
