Managing Inter-Chassis Links

FS6300 NMS Administrator’s Reference Guide

6.
Select the
Source Card
and
Destination Card
.
7.
Identify
Trunk Ports
on the source and destination cards.
Select the orange square icon
to view available ports. A pop-up window will display. Available ports
will be shaded in gray.
8.
Enter exactly the matching time slots for Source and Destination Trunk ports. While adding time slots
from the trunk ports into the Pool, FS6300 verifies that the timeslot specification is exactly matching. The
acceptable input for time slot specification is either a number or a range of numbers.
9.
Click

.
The FS6300 assigns a Pool ID and Trunk ID for the newly created pool. The record is listed in a table in the
Reserve Pools window. You cannot change the Pool and Trunk IDs.
You may repeat steps 2 through 8 to add more trunks and timeslots into the pool from the same source and
destination cards; or, to add new trunks and timeslots from different cards in the selected chassis.
The reference to Source and Destination chassis is for the purpose of tracking the two inter-connected chassis
and does not imply that one is the actual Source chassis and the other is the Destination chassis. For example:
If Trunk T1 is created between two chassis, CH1 and CH2 (Source and Destination), and Trunk T2 is created
between CH2 and CH1 (Source and Destination), only one Pool is created called CH1-CH2 for both T1 and
T2.
If the selected Chassis ID is a 6U on one side or both sides, a suffix, L (Left) or R (Right), is added to the end
of the Chassis ID.
The order in which you create the reserved pools is the order the FS6300 will use to prioritize the inter-chassis
links.
The status of the Pool is initially 'Free'. Based on utilization of reserved slots, FS6300 updates the status to
“Partial' or 'Used'. You are allowed to:
•
Remove an unused Pool
•
Add more timeslots from an already reserved Trunk Port to the Reserve Pool.
•
Remove/cancel timeslots added from a Trunk to a pool if not already used.
Synchronizing Maps and Trunks
Due to database backups, restores or manual configurations, the number of free slots available in the NMS
database may not accurately correspond with the source or destination cards in the trunk. The NMS updates
the number of available slots during the discovery/re-discovery process. The
Re-Calculate Free Slots
feature
compares the timeslot utilization between two cards of the trunk.
Note
If incorrect but matching map configurations exist on both of the cards, the
re-calculation feature will not display those configurations. For example, it
will not show a partial map on each of the cards that utilizes the same
timeslot created initially by the NMS. Also, currently the re-calculation fea-
ture does not consider the timeslots on the trunk that are used for In-band or
PPP links.
