This is a single line script that illustrates the exsh.clicmd () called from a Python script.
print exsh.clicmd('show switch', True)
In this example, the second parameter passed to exsh.clicmd () is True. This returns the CLI display output that would have normally been sent to the user. In this case, the line prints the output anyway, which is shown below.

In this example, we create a number of VLAN (Virtual LAN)s in the form of prefix tag and add tagged port lists to each VLAN. There are a number of methods for collecting user input and validating the data type. This example uses a simple while True: loop until the input is the correct type. A more robust example would also apply range checking etc… to the vlan tag(s). E.g. Create vlans with tags from 1000 to 1099 The prefix is ‘dave‘, so each vlan name will have a name like ‘dave1000‘, ‘dave1001‘ etc… The user provided port list will be added to each vlan name as tagged ports.
import sys
while True:
prefix = raw_input('enter vlan name prefix:')
if len(prefix):
break
while True:
reply = raw_input('beginning vlan tag:')
if reply.isdigit():
minTag = int(reply)
break
while True:
reply = raw_input('ending vlan tag:')
if reply.isdigit():
maxTag = int(reply)
break
if minTag > maxTag:
print 'Beginning vlan id cannot be greater than ending vlan id'
sys.exit(-1)
while True:
portlist = raw_input('port list:')
if len(portlist):
break
print 'Creating vlans from ',prefix+str(minTag),'to',prefix+str(maxTag)
for vlanId in range(minTag,maxTag + 1):
vlanName = prefix + '{0:>04d}'.format(vlanId)
cmd = 'create vlan '+vlanName + ' tag ' + str(vlanId)
print exsh.clicmd(cmd, True)
cmd = 'config vlan ' + vlanName + ' add port ' + portlist + ' tag'
print exsh.clicmd(cmd, True)
Note
UPM variables can be used with Python scripting. They must be passed as arguments of the script.
