Symptom 1: Changing from isolated to regular vlan and back to isolated, mac learning is not happening. Have primary vlan 5 and secondary isolated vlan 6 configured on a switch. On sending double tagged traffic with double tag (6,1000) it is observed that on changing the isolated vlan to regular vlan and back to isolated vlan results in the mac no longer getting learnt in primary vlan 5. On doing a shut/no shut of the primary vlan the mac gets learnt Symptom 2: Remove of private-vlan configuration from secondary vlan associated to primary leads to STP failure and such records in log: %STP-2-SET_PORT_STATE_FAIL: Port state change req to PIXM failed, status = 0x58001a [fu cqueue invalid node] vdc 1, tree id 0, num ports 1, ports state BLK, opcode MTS_OPC_PIXM_SET_MULT_CBL_VLAN_BM_FOR_MULT_PORTS, msg id (92191), rr_token 0x1681F %ETHPORT-5-IF_SEQ_ERROR: Error ("fu hashtable key not present") communicating with MTS_SAP_STP for opcode MTS_OPC_ETHPM_PORT_LOGICAL_CLEANUP (RID_PORT: Ethernet1/45)
Condition 1: vlan 6 no private-vlan isolated Condition 2: vlan 12 no private-vlan community
The workaround to recover from symptom 1 is 'doing shut/no shut on the primary vlan' Symptom 2 does not have a clean workaround
