IOM modes and descriptions
IOM mode
Description
Standalone mode (SMUX)
This is the factory default mode for the IOM. SMUX is a fully
automated, zero-touch mode that allows VLAN memberships to be
defined on the server-facing ports while all upstream ports are
configured in port channel 128 and cannot be modified.
VLT mode
In this low-touch mode, all configurations except VLAN membership
are automated. Port 9 is dedicated to the VLT interconnect in this
mode.
Programmable MUX mode
(PMUX)
PMUX mode provides operational flexibility by allowing the
administrator to create multiple LAGs, configure VLANs on uplinks
and to configure DCB parameters on the server-facing ports.
Stacking mode
In Stacking mode, multiple switches can be combined to make a
single logical switch, which is managed by a designated master unit in
the stack. This mode can be useful because it simplifies management
and redundant configurations.
Full Switch mode
In Full Switch mode, all switch features are made available. This mode
requires the most configuration, but allows for the most flexibility and
customization.
