Managing OmniSwitch 6855 Series Stacks Reloading Switches
OmniSwitch 6855 Series Hardware Users Guide September 2011 page 7-27
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 automati-
cally 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 informa-
tion on scheduling a primary module reload, as well as additional command details, refer to the
OmniSwitch CLI Reference Guide .
Reloading the Primary Management Module In a Stack of Three or More
In this stack of four OmniSwitches, the slot 1 switch is the pri-
mary management module. The slot 2 switch is the secondary.
Slots 3 and 4 are operating in idle roles.
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.
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.
