Error description
ITNM 3.8 FP5 Linux =================== Customer is using ITNM in a multiple virtual machines env connected on a switch port that is a trunking VLAN. The stitcher is connecting each of the VLAN trunk end points directly to the VMs. This meant that in cases where there were many VMs connected to the same physical switch port a large number of connections were being created ( numConnections = numberofVLANs * numberOfVMs ). I have changed the stitcher so that it will leave the VM connected to directly to the trunk port instead of to each of the VLAN trunk end points the port contains. This way of modelling things greatly reduces the number of connections in the NCIM database but will not alter the connectivity of the graph used for the RCA calculations or the connections which are displayed in the GUI.
Local fix
Recreate the stitcher by just reduce the number of connections to NCIM model whitch also affect the performance of the import of the topology to NCIM and the speed at which the GUI is able to display network views both during and after topology updates.
Problem summary
**************************************************************** * USERS AFFECTED: * * Users with an network that has many VLAN trunks connecting * * to many virtual machines * **************************************************************** * PROBLEM DESCRIPTION: * * The CreateTrunkConnections stitcher can create a very large * * number of connections when a large number of virtual * * machines are all connected to a trunk port which is trunking * * many VLANs. * **************************************************************** * RECOMMENDATION: * * | fix pack | 3.8.0-ITNMIP-FP0007 * ****************************************************************
Problem conclusion
The CreateTrunkConnections stitcher was modified to just maintain a single connection from the trunk port to each remote neighbour. The trunk ports were then upwardly connected to maintain connectivity for RCA purposes. | fix pack | 3.8.0-ITNMIP-FP0007 | fix pack | 3.9.0-ITNMIP-FP0001
