B-Series with multiple ports

[cslayton]

I have a python script that I’m using for B-series switches to configure multiple ports at the same time.

#@METADATASTART
#@ScriptDescription "Change port from static to NAC".
#@DetailDescriptionStart
##############################################################################
#
#Purpose: "Change port from static to NAC".
#
# Version : 1.0
#
# This script deletes selected ports from all vlans, sets "display-string" and
# "description-string" to "NAC_Port".  Finally, the configuration is saved.
##############################################################################
#@DetailDescriptionEnd
#
#@MetaDataEnd
import re
import commands

def main():
    
    if "port" in emc_vars:
        ports = emc_vars["port"]
    else:
        print "Please select at least one PORT if you start the script"
        return 0
    
    cli_result = emc_cli.send("clear port vlan " + ports)  

main()

However, I get the following output:

deerl1sw006(su)->clear port vlan ge.1.7,ge.1.8
Invalid Port in [port-string]. 

The B-Series switch needs to use ; instead of , to separate interfaces.  Is there anyway to fix this?

The code you posted is working fine.  I am trying to create a function out of the section that creates a list of all ports and then call that function.

Error:  SyntaxError: ("no viable alternative at input '('", ('<string>', 19, 3, 'def(port_list):\n'))

Hello Cuck,

what isn’t working?

Error message?

Trying to further refine this by creating functions, but the below doesn’t work.

import re
import commands

def(port_list):
    if "port" in emc_vars:
        ports = emc_vars["port"].split(",") #create a list with all ports
    else:
        print "Please select at least one PORT if you start the script"
        return 0
    
    portcounter = 0
    for port in ports: #walk through the list
        if portcounter == 0:
            portstring = port
        else:
            portstring = portstring + ";" + port #fill in the separator you need
        portcounter += 1
    
def main():

    cli_result = emc_cli.send("clear port vlan " + portstring)  
    cli_result = emc_cli.send("set port alias " + portstring + " NAC")
    cli_result = emc_cli.send("set macauthentication port enable " + portstring)
    cli_result = emc_cli.send("set multiauth port mode auth-reqd " + portstring)
    cli_result = emc_cli.send("set multiauth port numusers 4 " + portstring)
    cli_result = emc_cli.send("set pwa portcontrol enable " + portstring)
    cli_result = emc_cli.send("save config")

port_list() 
main()

Thanks so Much!
