Cnfrsrc Fails With "Available Channels Is 0; Cnfrsrc Fails With "Automatic Routing Management Is Currently Using The Channel Space - Cisco BPX-BXM-155-8DX Installation And Configuration Manual

Chapter 29 Troubleshooting

cnfrsrc fails with "available channels is 0"

When the user thinks that there are channels available, but cnfrsrc says that the number of available
channels is 0. The user will not be able to allocate any more vsi channels.
This might not be a problem because the user might not have accounted for hidden channel assignments
like networking and VSI vcs. Execute the
allocated. Note any channel assignment that looks suspicious. Verify this page with the channels
configured from the cnftrk and cnfrsrc command.
The dspchuse command is available to users in this release .
Workarounds
The work around depends on where the problem is. If it's with PVCs, try cnfrsrc and change the
number of pvcs. Since switchcc, will rebuild the channel database, try executing switchcc.
Here is a list of things that should be done:
•
•
•
Verify if anyone has disable a partition.
Disabling the partition will not recalculate the end_lcn value. The end_lcn will be recalculated by a
card reset or a switchcc or node rebuild.

cnfrsrc fails with "Automatic Routing Management is currently using the channel space"

This error is indicating that there are Automatic Routing Management channels currently configured on
the space that the user wants for VSI.
For example: Let's say the BXM card supports 100 channels. Currently 50 of the channels are
configured for PVCs and 50 for VSI ranging from 51–100. Let's suppose that the card has 5
connections on channel 45–49. Now change the configuration of PVCs to 10. The command will work
Release 9.3.0, Part Number 78-10674-01 Rev. D0, July 2001
capture the dspchuse screen and compare against the cnfrsrc and cnftrk command.
Verify the number of trunks that are upped. This will indicate the number of networking channels
assigned.
Note the number of vsi shelves added. For each vsi shelf added, 12 lcns are reserved on the BXM
attached to the controller and 1 lcn is reserved for all the other active BXM cards. Capture the
dspvsich command. For example:
slot 13:
–
2 vsi shelf added
–
– slot 11:
1 vsi shelf added
–
– slot 9:
– Two (2) trunks are upped
One (1) port is upped
–
On slot 13 – 25 lcns are reserved => 12 for each vsi shelf, and 1 for the shelf added to slot 11.
–
On slot 11 – 14 lcns are reserved => 12 for the vsi shelf, and 2 for the 2 shelves added on slot
–
13.
On slot 9 – 3 lcns are reserved => 2 for the 2 shelves added on slot 13, and 1 for the 1 shelf
–
added on slot 11.
