Hosted Operation of Cascaded Stinger MRT units
Traffic management in hosted MRT systems
HOST> set atm-connect-options nailed-group = 801
HOST> set atm-connect-options vci = 55
You can use standard ATM-related commands, such as atmvcx or atmvcl, to
display connection information in hosted systems. For example, the following
command displays information about virtual circuits on shelf 3:
HOST> atmvcx -sh 3
Profile
pvc-3-2-1
Restoring a remote shelf to standalone operations
After a unit's shelf-controller-type has been set to slave, you cannot restore
the system to standalone operations by simply changing the
shelf-controller-type setting to standalone. To restore a slave controller to
standalone mode, you must clear the system's NVRAM. For example:
admin> nvram -f
When the system comes up again following the nvram command, its
shelf-controller-type is set to standalone by default.
Traffic management in hosted MRT systems
With earlier software versions, upstream bandwidth was not configurable for
Stinger MRT platforms. Guaranteed upstream LIM bandwidth is now
configurable for MRT platforms as for other Stinger platforms. For details about
this type of configuration, see the Stinger ATM Configuration Guide.
Deprecated atm-config profile
In a hosted Stinger MRT system, the total amount of LIM bandwidth varies when
remote shelves are added or removed. To accommodate this environment, ATM
parameters previously located in the atm-config profile have been relocated in
the system or slot-static-config profiles, and the atm-config profile has been
deprecated.
The system creates a slot-static-config profile for a remote LIM dynamically,
when the associated remote-shelf-config profile is created (written).
Note
existing configurations from the deprecated atm-config profile to their new
locations, as shown in Table B-2. The parameters still work as described in the
Stinger ATM Configuration Guide and Stinger Reference Guide.
