Redundantly Connected There are at least two independent paths between any pair of
interconnects in the logical interconnect, and there are at least
two independent paths from any downlink port on any
interconnect in the logical interconnect to any other port (uplink
or downlink) in the logical interconnect.
Connected There is a single path between any pair of interconnects in the
logical interconnect, and there is a single path from any downlink
port on any interconnect in the logical interconnect to any other
port (uplink or downlink) in the logical interconnect.
Disconnected At least one interconnect is not connected to the other member
interconnects in the logical interconnect.
The configuration defined in the logical interconnect group is the expected configuration within
the enclosure. If any of the interconnects are defined to be in the Configured state but instead
are in a different state, such as Absent, Inventory, or Unmanaged, the stacking health is
displayed as Disconnected. If none of the interconnects are in the Configured state, no
stacking health information is displayed.
Adding a logical interconnect
Every enclosure belongs to an enclosure group. When you add an enclosure:
•
The appliance detects the physical interconnects and their stacking links.
•
The appliance automatically creates a single logical interconnect for the enclosure. The
configuration of the logical interconnect, including uplink sets, is defined by the logical
interconnect group associated with the enclosure group. This ensures that all enclosures in the
enclosure group are configured with the same network connectivity.
•
The appliance automatically names the logical interconnect when you add the enclosure. The
naming convention for logical interconnects follows:
enclosure_name-LI
Where enclosure_name is the name of the enclosure.
Deleting a logical interconnect
To delete a logical interconnect, you must remove the enclosure from management.
19.2.4 About logical interconnect groups
A logical interconnect group is associated with an enclosure group and is used to define the logical
interconnect configuration for every enclosure that is added to that enclosure group. Logical
interconnect configurations include the I/O bay occupancy, stacking mode, uplink ports and uplink
sets, available networks, and downlinks.
The logical interconnect group reserves the appropriate interconnect ports for stacking links required
for the stacking mode. For the enclosure stacking mode:
•
All interconnects in an enclosure are members of the logical interconnect.
•
Horizontally adjacent interconnects must be the same interconnect type.
•
Horizontally adjacent interconnects reserve one port per enclosure for internal stacking links,
called East-West links.
•
Vertically adjacent interconnects reserve an additional port per enclosure for external stacking
links, called North-South links.
The uplink sets portion of the logical interconnect group defines the initial configuration for uplink
sets for each enclosure added to the enclosure group. You can change the uplink sets for a logical
interconnect, and existing enclosures are not affected by changes you make to uplink sets in the
