When there is a mismatch between the software running on the switch and the software on the IOC module, the switch updates the IOC module to the version of software running on the switch. During this process you see errors that are similar to the following:
IO1 [12/06/17 11:50:43.513:UTC] 0x0024854b 00000000 GlobalRouter SF-APP WARNING FabDrv_lc::mapLocalPortsToSysports dnxBcm_assignSysPortToModPort failed: unit=0 sysport=0 modId=40000 tmPort=1 IO1 [12/06/17 11:50:43.526:UTC] 0x0024854b 00000000 GlobalRouter SF-APP WARNING FabDrv_lc::configIngressSideVOQs: UNKNOWN PORT TYPE OF 773 localPort = 1 modId = 6 IO7 [12/06/17 11:50:45.673:UTC] 0x0024854b 00000000 GlobalRouter SF-APP WARNING FabDrv_lc::createVoqsForPort: dnxBcm_setPacketLengthAdjustForVoq failed: unit=0 voqBaseId=80000512 cos=4 PACKET_LENGTH_ADJUST=0 IO7 [12/06/17 11:50:45.688:UTC] 0x0024854b 00000000 GlobalRouter SF-APP WARNING map_local_port_to_connectorPort: INVALID LOCAL PORT OF 10000000
The messages stop once the update of the IOC module software has completed. This has no impact on the switch operation.
Note
This issue applies only to a switch running a mix of releases. For example, there is a mismatch if the switch is running release 6.1.x or higher and it has an IOC running release 4.5.x.
