Known Issues List

Access

Bug Number Notes
1469164 802.1X: More than one device group on a single port is not supported for 802.1X NGPF protocol emulation.
1469710 802.1X: Legacy option "Use VLAN to Identify Supplicant" is not supported in NGPF.
1470436 802.1X: If the user stops the 802.1X NGPF sessions one-by-one, and restarts again then the new stats will be added to the previous stats. User should manually clear the statistics using "Clear All Statistics" command before starting the protocols to avoid the addition of stats.

High Level API

Bug Number Notes
1473726 A field accepting value in hex format cannot be modified through HLAPI if its pattern is selected as Repeatable Random. Other patterns can be used for such fields.

Routing/switching

Bug Number Notes
1467521 The two fields Type and SubType of Exte-Community are interrelated for a few parameters. For a correct configuration for Type EVPN, Subtype should be Routers's MAC and for LinkBW subtype should be extendedBW. Subtype gets selected automatically when corresponding type is selected. The value of some Type filed is directly co-related with the value of Some Sub-type filed. That's why Overlay index is not applicable for those fields for this release.
1470117 In NGPF, though Simulated Topology could be connected to OSPF or IS-IS layer connector, it may not work. As a workaround always connect Simulated Topology to Ethernet connector.
1477065 In NGPF BGP GUI, column "Custom SID Type" in the "BGP 3107" configuration tab under BGP Peer is removed. This configuration is now added in the BGP Port Properties under SRv6 tab with name "Prefix SID Attr Type". If any existing configuration is using a non-default value for this field then it needs to be re-configured in this new location.
1477727 There is an issue of GUI hang for Statistical Route Distribution (SRD) skip loopback and skip multicast feature in BGP. Issue arises when user tries to configure higher ipv4 address like 10000 or above with lower Prefix Length Start value below 16. Workaround is to configure Prefix Length Start value equal to or above 16.

SDN

Bug Number Notes
1477608 NGPF Openflow Controller session can go to bad state if user tries to trigger the learned information without any pause. Users are advised to wait for ongoing learned info actions to complete before triggering the next learned information. User can also recover the session by stopping and starting the protocol again.

TCL

Bug Number Notes
1473413 Users should not use old scriptgen API ["ixNet exec scriptgen"] which is deprecated. Instead they should switch to newer one ["ixNet exec generate /globals/scriptgen"].
1473772 While setting IPv4 address Multi Values to Custom through TCL script can throw some error like : Object reference not set to an instance of an object

Resolved Defects List

High Level API

Bug Number Notes
1474859 An issue with creating AS_Path and AS_Path Segments in BGP route range through HLAPI is fixed.

MPLS

Bug Number Notes
1473788 VPLS Traffic picks up wrong MPLS label.
1474386 ARP does not get resolved over LDP VPWS pseudowire.
