Stack Management

STEP 1

• Downlink port configuration—IF the stack included a unit of one type (for example
GE unit) and this unit is replaced by a unit of a different type (for example FE unit)
most of the port based configuration (VLANs, STP, ACL, 802.1x etc) are applied
automatically to the new port type. Some static port-type-related configuration will fail
and errors might be reported (for example if port speed was configured to 1GB, and
this port number in the new unit supports up to 100Mbps speed), but this will not cause
the rest of the configuration to fail. The failed commands remain part of the stack
running and startup configuration file, however upon system reload they will be
removed from new running configuration file.
• Uplink ports configuration—If the old and new unit types were changed between FE
and GE, the configuration matches both on the new and old unit types (since uplink
ports are always XG ports). Therefore, configuration of uplink ports are applied to new
units with no error.
When replacing an FE/GE device (which supports uplink port type) with an XG device (which
do not support uplink port type), the uplink port configuration on the newly-inserted XG
device is saved to a special interface type with ID of 49-52. This interface type is reserved to
indicate that the interface is not present.
When replacing a unit/interface type, the running and startup configuration files are modified
to correctly display the interface type. For example, if an old unit was an FE unit type with
interface ID FE1/0/1, when it is replaced with a GE unit type, the running/startup
configuration (and CLI show commands) automatically display the configuration under GE1/
0/1.
To configure the stack:
Click Administration > Stack Management.
The operational status of a standalone device or a stack is displayed in the Stack Operational
Status block.
• Stack Mode—Displays one of the following options:
- Native Stacking—Device is part of a stack in which all of the units are of the same
type.
- Hybrid Stacking—Device is part of a stack that can consist of either mixed types of
350 devices or mixed types of 550 devices (but not a mix of 350 and 550 devices).
• Stack Topology—Displays whether the topology of the stack is chain or ring.
