Add 2 B2B ports and Configure IS-IS. # 2. Configure 1 Route Range with 1000 Routes per range # and (20 * 20) Network Ranges. # 3. Configure Rate Control Interval = 1000 ms and # LSPs per Interval = 10 at first. # 4. Enable the packet capture and run IS-IS. # 5. Wait for 20 secs after the protocol is started and Stop # the packet capture. # 6. Perform ALL verification steps listed below # 7. Start Capture & Disable/Enable the Route Range & Network # Range simultaneously. # 8. Stop Capture Stop Protocol # 9. Perform ALL verification steps listed below # 10. Configure LSPs per Interval = 20 and repeat step 4 - 9 # Verification : 1. Verify from stat viewer that the IS-IS sessions are UP # with Rate Control configured. # 2. For each set of values and for each verification step # verify # the Rate Control Interval & LSPs per Interval through # packet capture. # 3. Verify that the No. of LSPs send MUST NOT exceed the # configured # value within the Rate Control Interval configured. # In the packet capture, consider the timestamp (T0) of # first LSP found as starting timestamp and then add the # configured "Rate Control Interval" value to that # timestamp. Let the resultant timestamp be a value T1. # Verify that no more LSPs than the configured # "LSPs per Interval" have been transmitted within the # time period (T1 - T0). # 4. Verify the value of the new stat field # "Rate Control Blocked Sending LSP/MGROUP" is being # populated (i.e. value greater than 0) # Config Format : ixncfg used #------------------------------------------------------------------------------ proc Action {portData1 portData2} { source $::pwd/rateControlUtils.tcl # initialize return value set FAILED 1 set PASSED 0 # Get real card1/port1 from portData set chassisIp1 [getChassisIp $portData1] set card1 [getCardNumber $portData1] set port1 [getPortNumber $portData1] # Get real card2/port2 from portData set chassisIp2 [getChassisIp $portData2] set card2 [getCardNumber $portData2] set port2 [getPortNumber $portData2] # Hostname, where IxNetwork TCL-Server client runs set tclPublisherVersion "5.40" set hostName [lindex [getHostName $portData1] 0] set connection_Result [connectToClient $portData1 $portData2 \ $tclPublisherVersion] log "Connection Result: $connection_Result" if {[string equal $connection_Result "::ixNet::OK"] != 1} { log "connection to client unsuccessful" return $FAILED } log "connectToClient Successful" # clean up all the existing configurations from client log "cleaning up the client" ixNetCleanUp after 2000 # load config files set configFileName config.[getTestId].ixncfg if {[ixNet exec loadConfig [ixNet readFrom $::pwd/$configFileName]] != \ "::ixNet::OK"} { log "Loading IxNetwork config file : Failed " ixNetCleanUp return $FAILED } log "Loading IxNetwork config file : Passed" # getting the real port list set realPortsList [list [list $chassisIp1 $card1 $port1] \ [list $chassisIp2 $card2 $port2]] # Assign real ports to virtual ports log "getting virtual ports ...." set vPorts [ixNet getList [ixNet getRoot] vport] set vPort1 [lindex $vPorts 0] set vPort2 [lindex $vPorts 1] log "Virtual ports are = $vPorts" # Assign virtual ports to real ports log "Assign virtual ports to real ports ..." set force true set status [ixTclNet::AssignPorts $realPortsList {} $vPorts force] log "Assigned: $status" if {[string equal [lindex $status 0] $vPort1] != 1 || \ [string equal [lindex $status 1] $vPort2] != 1} { ixNetCleanUp return $FAILED } ixTclNet::CheckLinkState $vPorts doneList after 2000 # Enable & Start Capture log "Enable & Start Capture..." if {[enableCaptureMode $vPorts] == 1} { log "Failed to enable capture..." ixNetCleanUp return $FAILED } ixNet exec startCapture # Repeat twice - once for lspMgroupPdusPerInterval = 10 # and once for lspMgroupPdusPerInterval = 20 foreach lspMgroupPdusPerInterval {10 20} { # Start Protocols log "Starting protocol ISIS (Level 1)..." if {([ixNet exec start $vPort1/protocols/isis] != "::ixNet::OK") || \ ([ixNet exec start $vPort2/protocols/isis] != "::ixNet::OK")} { log "Failed to start protocol ISIS (Level 1)..." ixNetCleanUp return $FAILED } log "Protocol started" log "Waiting for 60 Sec for protocol Sessions to be up" after 60000 ixNet exec stopCapture # Verify Starts log "Verifying ISIS (Level 1) protocol stats ..." set ISISStatsList {"L1 Sess.
