Script for assigning interfaces to port channels (create_po.py)

The create_po.py script is an example for automating common configuration tasks. This script runs the relevant show running-config commands before and after the following actions:

VLAN configuration
Port-channel configuration
Adding interfaces to port channels

Note

Lines beginning with # are annotations.

#Required in all scripts for SLX-OS:
from CLI import CLI

slot = [0]
interfaces = [28, 29, 30, 31]
port_channel = 10
vlan_range = "101-105"

# Runs show running-config int vlan before the configuration, and assigns this SLX
# command to a Python variable named cmd_show_running_vlans.
cmd_show_running_vlans = CLI("show running-config vlan")

# Configures VLANs.  {} is a placeholder for the format (arg1, arg2, ... argN) variables:
cmd_configure_vlans = CLI("config \n vlan {}".format(vlan_range))

# Reruns show running-config int vlan, following definition of new VLANs:
cmd_show_running_vlans.rerun()

# Configures port channel (vLAG):
cmd_show_running_port_channels = CLI("show running-config int po")
cmd_configure_port_channel = CLI("config \n int po {} \n switchport \n switchport mode trunk \n switchport trunk allowed vlan add {} \n switchport trunk tag native-vlan ; no shut".format(port_channel, vlan_range))

# Reruns show running-config int po, following configuration changes:
cmd_show_running_port_channels.rerun()

# Adds interfaces to port channel (vLAG)

for interface in interfaces:
    cmd_configure_interface = CLI("config \n int eth {}/{} \n channel-group {} mode active type standard \n no shut".format(slot, interface, port_channel))
    cmd_show_running_int_tengig = CLI("show running-config int eth {}/{}".format (slot, interface))

# Runs show running-config:
cmd_show_running = CLI("show running-config")

Run-log (create_po.py)

A log upon running create_po.py was as follows:
