  2. VPP functional test environment changes

    • upgrade to Ubuntu 16.04
    • VM and vhost-user test environment optimizations
  3. Introduction of Centos tests

  4. Added VPP functional tests

    • more VM vhost-user tests
    • more LISP tests
    • more IPSec crypto tests
    • IPv4 and IPv6 Equal-Cost Multi-Path routing tests
    • Telemetry: - IPFIX tests - SPAN tests

4.2.2. Known Issues

Here is the list of known issues in CSIT rls1701 for VPP functional tests in VIRL:

# Issue Description
1 DHCPv4 client: Client responses to DHCPv4 OFFER sent with different XID Client replies with DHCPv4 REQUEST message when received DHCPv4 OFFER message with different (wrong) XID.
2 Softwire - MAP-E: Incorrect calculation of IPv6 destination address when IPv4 prefix is 0 IPv6 destination address is wrongly calculated in case that IPv4 prefix is equal to 0 and IPv6 prefix is less than 40.
3 Softwire - MAP-E: Map domain is created when incorrect parameters provided Map domain is created in case that the sum of suffix length of IPv4 prefix and PSID length is greater than EA bits length. IPv6 destination address contains bits writen with PSID over the EA-bit length when IPv4 packet is sent.
4 IPv6 RA: Incorrect IPv6 destination address in response to ICMPv6 Router Solicitation Wrong IPv6 destination address (ff02::1) is used in ICMPv6 Router Advertisement packet sent as a response to received ICMPv6 Router Solicitation packet.
5 IPFIX: IPv6_src key name reported instead of IPv6_dst The report contains IPv6_src key name instead of IPv6_dst when classify session is configured with IPv6 destination address. Anyhow the correct IPv6 destination address is reported.
6 SPAN: Tx traffic is not mirrored Tx traffic is not mirrored from SPAN source port to SPAN destination port.
NOTE: Fix is going to be merged in vpp stable/1701.
7 SPAN: Packet trace always contains local0 as destination port There is reported wrong destination port in the traffic trace:
SPAN: mirrored GigabitEthernet0/5/0 -> local0
The (Rx) traffic is mirrored to correct destination port.

4.2.3. Tests to be Added - Centos

CSIT rls1701 added Centos functional test execution environment in FD.io VIRL testbeds.However due to the factors beyond CSIT project control execution of those tests within the LF FD.io test environment still need to complete. Once the results become available, they will be published as an addendum to the current version of CSIT rls1701 report.
