Known Issue List

Infrastructure

Bug Number Notes
18922 ANCP protocol stack is not getting added properly using the wizard for device groups with an existing ANCP stack.
18957 Support for learning neighbor from multicast Neighbor Solicitation message is not available.
3777 Designer and Data Analysis has been made EOL.
16864 In some scenarios, while running Wireshark with filter, it is unable to set the filter when data traffic is still running. As a workaround, set the filter first, and then start the capture.
18516 LLDP should be disabled while running any kind of performance, regression, long Duration tests. It should be enabled only to fetch Peer information.
19044 The existing attribute of guardrailEnabled has been moved from ::ixNet::OBJ-/statistics to ::ixNet::OBJ-/globals/statistics/advanced/guardRail. It has been renamed as enableGuardrail and the former has been deprecated.
19076 If skip reboot options are enabled in the Debug window, namely, 1)Skip Port reboot in NGPF to NGPF 2)Skip Port reboot in NGPF to Classic, then all the ports should be manually rebooted once after making the changes.
19255 Port may go into bad state if IPv4 traffic over Lag is running without any flow tracking.

VM

Bug Number Notes
933 Please configure VFs in VMware ESXi using the following command: esxcli system module parameters set -a -m i40enu -p "trust_all_vfs=1,1"
18906 If startup of IxVM load module fails with "Invalid memory setting" error, make sure that sufficient memory is reserved.
19185 While running packets with minimum frame size (64Bytes) and VLAN, the vmxnet3 driver from the VMware ESXi hosts add extra 4 bytes of padding at the end of the packet.
19187 On protocol-heavy configurations some protocols like OSPF have a low timeout interval. If they do not receive the response quickly enough, they fail to negotiate. Workaround is to gradually start protocols using a setup rate. This is applicable on runs with SR-IOV.
19085 The Topology Discovery function which displays Peer Information fetched via LLDP is not available on Virtual Ports.
19182 In order to get VLAN and Promiscuous mode to work with Intel NICs (700 and 800 Series) on VMware ESXi environments, use the intnet plugin that can be downloaded from the Intel website.
19183 In order to get VLAN and Promiscuous mode to work with Mellanox NICs (ConnectX-4, ConnectX-5, and ConnectX-6) on VMware ESXi environments, use the nmlxcli plugin that can be downloaded from the Mellanox website.
19189 In KVM environments the NICs need to be unamanaged by Network Manager as NM sends DHCP Discover messages that will appear in Rx.
19190 In KVM environments for Intel 700 and 800 series please make sure that the following settings are applied to the NICs on the host: ip link set dev NIC_NAME up ip link set dev NIC_NAME mtu 9000 ip link set dev NIC_NAME promisc off ip link set dev NIC_NAME allmulticast off ethtool --set-priv-flags NIC_NAME vf-true-promisc-support on For SR-IOV VFs please apply the following settings: ip link set dev NIC_NAME vf VF_ID trust on ip link set dev NIC_NAME vf VF_ID spoofchk off
19191 The Physical Function (PF) driver on Intel 800 Series NICs can be unstable at times. The symptoms on VM ports can be connectivity issues or link down. When this happens, verify the dmesg output on the KVM hosts and then reboot the host.
