Troubleshooting Commands
since only five (5) are currently used. The available channels on the card is now 40. If cnfrsrc is
executed now to increase the number of VSI channels, the command will fail, because channels 45–49
are currently in use.
To check if a specific connection is using a channel out of range:
• Verify channel number (LCN) used by the connection by using the command dcct.
• Get VSI end LCN using dsplogcd—field mc_vsi_end_lcn
• In normal conditions, the value of mc_vsi_end_lcn should be greater than LCN.
To check if any connection in the port or trunk card is using a channel out of range.
– GetVSIendLCNusingdsplogcd—field mc_vsi_end_lcn
– Use dspchmap to display the map of lcns used by connection in the card; in normal conditions
no LCN higher than mv_vsi_end_lcn should be associated with an Automatic Routing
Management connection or trunk xlat.
Workarounds
The only work around is to somehow delete the connections currently using the high end of the channel
range. On the trunk interface, causing the connections to reroute will likely cause the lower lcn range
to be used first. On the port interface, deleting and re-adding the connection.
