Split Dial Shelves
If the dial-shelf split slots command is entered in normal mode without valid slot numbers or the
keyword none, the command is rejected.
Split mode: This command will change dial-shelf slot ownership. The router will no longer have
ownership of any dial-shelf slots.
no dial-shelf split slots
Normal mode: This command has no effect. If the router shelf is in normal mode, it stays that way.
Split mode: This command changes the router shelf to normal mode if it is in split mode, and the
other router shelf has already relinquished control of all dial-shelf slots or is switched off.
dial-shelf split slots {slot_numbers}
Normal mode: This command changes the router shelf to split mode with ownership of the slots
listed. Valid slot numbers are 0 through 11.
– In case of conflicting slot assignments, the command is rejected and a warning message is
issued.
– OIR events on all slots are detected by both DSCs and added to the list of feature boards
physically present in the dial shelf. However, OIR event processing is done only for assigned
slots.
Split mode: This command adds the dial-shelf slots listed to the router shelf’s list of owned
dial-shelf slots. The effect of multiple commands is cumulative.
dial-shelf split slots remove {slot_numbers}
Normal mode: This command has no effect.
Split mode: This command removes the dial-shelf slots listed from the router shelf’s list of owned
dial-shelf slots. The effect of multiple commands is cumulative.
Split-Dial-Shelf Error Messages
New error messages for various split-dial-shelf conditions include:
Duplicate priority clock source configured on other router shelf.
Explanation
The configuration commands for the master clock specify the clock sources and a
priority for each source. Together, these commands define a prioritized list of the clock sources used
to generate the master clock. This list, configured on the router shelf, is passed to and stored by the
DSC providing the active clock. In the event of failure of the highest priority clock source, the DSC
switches to the source with the next highest priority.
With a split dial shelf, clock sources can be configured on either of the router shelves from the slots
that each shelf owns. All valid clock source configurations are known to the DSC providing the
clock, including the clock sources configured on the other router or DSC.
This error condition results when a clock source input on one router is configured to have the same
priority as one configured on the other router. The original configuration command is not rejected;
however, these error messages are issued to both routers. The two inputs, with identical priorities,
both go into the ordered list of clock sources, but the one received first by the DSC providing the
active clock is assigned a higher priority.
Action Reconfigure the clock sources on the two routers so that they have different priorities.
