It will create 2 OSPFv2 topologies, each having an ipv4 network # # topology and loopback device group behind the network group(NG) with # # loopback interface on it. A loopback device group(DG) behind network # # group is needed to support applib traffic. # # 2. Start the ospfv2 protocol. # # 3. Retrieve protocol statistics. # # 4. Retrieve protocol learned info. # # 5. Enable the Ospfv2 simulated topologies External Route type1, which # # was disabled by default and apply change on the fly. # # 6. Retrieve protocol learned info again and notice the difference with # # previously retrieved learned info. # # 7. Configure L2-L3 traffic. # # 8. Start the L2-L3 traffic. # # 9. Retrieve L2-L3 traffic stats. # # 10. Stop L2-L3 traffic. # # 11. Stop all protocols. # # Ixia Software: # # IxOS 6.80 EA # # IxNetwork 7.40 EA # # # ################################################################################ ################################################################################ ################################################################################ # Utils # ################################################################################ # Libraries to be included # package require Ixia # Other procedures used in the script, that do not use HL API configuration/control procedures from pprint import pprint import sys, os import time, re # Append paths to python APIs (Linux and Windows) # sys.path.append('/path/to/hltapi/library/common/ixiangpf/python') # sys.path.append('/path/to/ixnetwork/api/python') from ixiatcl import IxiaTcl from ixiahlt import IxiaHlt from ixiangpf import IxiaNgpf from ixiaerror import IxiaError ixiatcl = IxiaTcl() ixiahlt = IxiaHlt(ixiatcl) ixiangpf = IxiaNgpf(ixiahlt) try: ErrorHandler('', {}) except (NameError,): def ErrorHandler(cmd, retval): global ixiatcl err = ixiatcl.tcl_error_info() log = retval['log'] additional_info = '> command: %s\n> tcl errorInfo: %s\n> log: %s' % (cmd, err, log) raise IxiaError(IxiaError.COMMAND_FAIL, additional_info) ################################################################################ # Connection to the chassis, IxNetwork Tcl Server # ################################################################################ chassis_ip = ['10.216.108.82'] tcl_server = '10.216.108.82' port_list = [['8/3', '8/4']] ixnetwork_tcl_server = '10.216.108.49:8999'; cfgErrors = 0 print "Printing connection variables ...
