From da8aebf2e722f2c441a03b300de71f9143d010a3 Mon Sep 17 00:00:00 2001 From: Juraj Sloboda Date: Tue, 23 Feb 2016 15:03:13 +0100 Subject: Modify sweep ping test cases - Write separate sweep ping test cases for jumbo frames - Compute sweep ping end size from reported MTU on DUT interface - Set MTU on TG according to MTU on DUT interface - Log VPP packet traces on IPv4 and IPv6 tests failure - Remove VM_ENV tag from sweep ping test cases for jumbo frames Change-Id: I47aa7977bcff9c4366c67578aef542924a1d055b Signed-off-by: Juraj Sloboda --- resources/libraries/robot/interfaces.robot | 15 +++++++++++++++ resources/libraries/robot/ipv4.robot | 14 ++++++++------ resources/libraries/robot/ipv6.robot | 26 +++++++++++++------------- 3 files changed, 36 insertions(+), 19 deletions(-) (limited to 'resources/libraries/robot') diff --git a/resources/libraries/robot/interfaces.robot b/resources/libraries/robot/interfaces.robot index 18c9c0cc81..649ee63253 100644 --- a/resources/libraries/robot/interfaces.robot +++ b/resources/libraries/robot/interfaces.robot @@ -11,6 +11,8 @@ # See the License for the specific language governing permissions and # limitations under the License. *** Settings *** +| Library | resources.libraries.python.InterfaceUtil +| Library | resources.libraries.python.NodePath | Resource | resources/libraries/robot/vat/interfaces.robot *** Keywords *** @@ -18,3 +20,16 @@ | | VPP reports interfaces through VAT on | ${node} #| | VPP reports interfaces through ODL on | ${node} #| | VPP reports interfaces through DEBUGCLI on | ${node} + +| Setup MTU on TG based on MTU on DUT +| | [Documentation] | Type of the tg_node must be TG and dut_node must be DUT +| | [Arguments] | ${tg_node} | ${dut_node} +| | Append Nodes | ${tg_node} | ${dut_node} +| | Compute Path +| | ${tg_port} | ${tg_node}= | First Interface +| | ${dut_port} | ${dut_node}= | Last Interface +| | # get physical layer MTU (max. size of Ethernet frame) +| | ${mtu}= | Get Interface MTU | ${dut_node} | ${dut_port} +| | # Ethernet MTU is physical layer MTU minus size of Ethernet header and FCS +| | ${eth_mtu}= | Evaluate | ${mtu} -
