Since this process will directly edit the master file, please be sure to back up the master file before proceeding.

What you can do with these steps

You can execute the following "add" command from the CLI.

Basic syntax:

python [file path]/network_sketcher.py [command] --master [master file path]
  • The part marked as [command] 、--master [master file path] below can be modified.
    python [file path]/network_sketcher.py -master [master file path] [command]

delete ip_address

This function deletes the IP address of a Layer 3 interface. You can delete one IP address at a time.

python [file path]/network_sketcher.py delete ip_address [device name] [layer3_portname] [ip_address/subnetmask] --master [master file path]
  • ex.

+BEFORE+
#python .\network_sketcher.py show l3_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW2', 'Vlan 100', '', '192.168.100.100/24']

+IP Address deleted+
＃python .\network_sketcher.py delete ip_address 'L3SW2' 'Vlan 100' '192.168.100.100/24' --master "C:\work\[MASTER]test.xlsx"
--- IP Address deleted --- L3SW2,Vlan 100,192.168.100.100/24

+AFTER+
#python .\network_sketcher.py show l3_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW2', 'Vlan 100', '', '']

delete l2_segment

This function deletes the Layer 2 segment (such as VLAN) configured on the interface. You can delete one Layer 2 segment at a time.

python [file path]/network_sketcher.py delete ip_address [device name] [layer2_portname] [l2segment_name] --master [master file path]
  • ex.

+BEFORE+
#python .\network_sketcher.py show l3_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW2', 'GigabitEthernet 0/0', '', 'Vlan100,Vlan200,Vlan300,addvlan999', '']

+l2_segment deleted+
＃python .\network_sketcher.py delete l2_segment 'L3SW2' 'GigabitEthernet 0/0' 'addvlan999' --master "C:\work\[MASTER]test.xlsx"
--- l2 Segment deleted --- L3SW2,GigabitEthernet 0/0,addvlan999

+AFTER+
#python .\network_sketcher.py show l3_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW2', 'GigabitEthernet 0/0', '', 'Vlan100,Vlan200,Vlan300', '']

delete portchannel

The port channel (LAG) configured on the Layer 1 interface will be deleted, along with the Layer 2 segment configured on the port channel.

python [file path]/network_sketcher.py delete portchannel [device name] [layer1_portname] --master [master file path]
  • ex.

+BEFORE+
#python .\network_sketcher.py show l2_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW1', 'GigabitEthernet 0/0', 'PortChannel 1', 'vlan1', '']
['L3SW1', 'GigabitEthernet 0/1', 'PortChannel 1', 'vlan1', '']

#python .\network_sketcher.py show l3_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW1', 'PortChannel 1', '', '']

+portchannel deleted+
＃python .\network_sketcher.py delete portchannel 'L3SW1' 'GigabitEthernet 0/0' --master "C:\work\[MASTER]test.xlsx"
--- portchannel deleted --- L3SW1,GigabitEthernet 0/0,PortChannel 1

＃python .\network_sketcher.py delete portchannel 'L3SW1' 'GigabitEthernet 0/1' --master "C:\work\[MASTER]test.xlsx"
--- portchannel deleted --- L3SW1,GigabitEthernet 0/1,PortChannel 1

+AFTER+
#python .\network_sketcher.py show l2_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW1', 'GigabitEthernet 0/0', '', '', '']
['L3SW1', 'GigabitEthernet 0/1', '', '', '']

#python .\network_sketcher.py show l3_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW1', 'GigabitEthernet 0/0', '', '']
['L3SW1', 'GigabitEthernet 0/1', '', '']

delete virtual_port

This will delete Layer 3 interfaces such as VLAN interfaces (SVIs).This command cannot be used to delete a port channel.

python [file path]/network_sketcher.py delete virtual_port [device name] [virtual_portname] --master [master file path]
  • ex.

+BEFORE+
#python .\network_sketcher.py show l2_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW2', '', 'addvlan 999', '', '']
['L3SW2', '', 'Vlan 300', 'Vlan300', '']

#python .\network_sketcher.py show l3_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW2', 'Vlan 300', '', '']
['L3SW2', 'addvlan 999', '', '']

+virtual_port deleted+
＃python .\network_sketcher.py delete virtual_port 'L3SW2' 'addvlan 999' --master "C:\work\[MASTER]test.xlsx"

+AFTER+
#python .\network_sketcher.py show l2_interface --master "C:\work\[MASTER]test.xlsx"
['L3SW2', '', 'Vlan 300', 'Vlan300', '']

['L3SW2', 'Vlan 300', '', '']

delete vport_l1if_direct_binding

This command deletes a virtual port connected to a layer 1 port. This command also deletes layer 2 elements such as VLANs connected to the virtual port.

python [file path]/network_sketcher.py delete vport_l1if_direct_binding [device name] [vport_name_direct_binding] --master [master file path]
  • ex.

+BEFORE+
#python .\network_sketcher.py show l2_interface --master "C:\work\[MASTER]test.xlsx"

+vport_l1if_direct_binding deleted+
＃python .\network_sketcher.py delete vport_l1if_direct_binding "Catalyst 3560" "GigabitEthernet 0/0.100" --master "C:\work\[MASTER]test.xlsx"

+AFTER+
#python .\network_sketcher.py show l2_interface --master "C:\work\[MASTER]test.xlsx"
['Catalyst 3560', 'GigabitEthernet 0/0', '', '', '']

delete vport_l2_direct_binding

Remove elements that send and receive layer 2 traffic, such as VLAN (l2_segment), directly from the virtual port.

python [file path]/network_sketcher.py delete vport_l2_direct_binding [device name] [virtual port] [l2_name_direct_binding] --master [master file path]
  • ex.

+BEFORE+
#python .\network_sketcher.py show l2_interface --master "C:\work\[MASTER]test.xlsx"
['Catalyst 3560', 'GigabitEthernet 0/0', 'GigabitEthernet 0/0.100', '', 'vlan100']

+virtual_port deleted+
＃python .\network_sketcher.py delete vport_l2_direct_binding "Catalyst 3560" "GigabitEthernet 0/0.100" “vlan100” --master "C:\work\[MASTER]test.xlsx"
--- vport_l2_direct_binding deleted --- Catalyst 3560,GigabitEthernet 0/0.100,vlan100

+AFTER+
