Hello,

Is it possible to somehow choose the name of VLANs that are dynmically assigned by Control? I am using FA and control to assign the VLANs and the VLAN will always be named SYS_VLAN_Number. If I am using different VLANs for voice per stack, I would like those to be named VOICE on the stack, so if push lldp med policy commands, I just have to specificy the vlan name “VOICE”?

Thanks.

Hi all,

created a simple script for setting the correct names on FA vlan’s. In the script you can give the ip address of the source/uplink switch. The script queries the local switch and queries the XMC data for the vlans of the uplink switch and changes the name of the vlans if they are not the same as the source/uplink switch.

from xmclib import cli
from device import api
from xmclib import logger
from xmclib import emc_vars
import re

## Script for setting vlan names on ERS FA switches.

def sendConfigCmds(cmds): 
    for cmd in cmds:
        cli_results = emc_cli.send( cmd )
        if cli_results.isSuccess() is False:
            print 'CLI-ERROR: ' + cli_results.getError()
            wf_error("CLI ERROR EXECUTING CLI COMMANDS")
            status = emc_results.Status;
            emc_results.setStatus( status.ERROR )
    cli_lines = cli_results.getOutput()
    return cli_lines

def AddCommandChangeVlan (vlanName,vlanID):
    global varCMDS
    varCMDS.append('vlan name %s "%s"' % (vlanID,vlanName))
    return

## Ip of the uplink switch ( core or datacentre )
varUplink_SW = "SET IP OF UPLINK/SOURCE SWITCH"


## Get local vlans of the switch
varCMDS = []
varCMDS.append('enable')
varCMDS.append('sh vlan type port')
varCli_result = sendConfigCmds(varCMDS)

regex = re.compile(r"(\d+) +(.+?)\s+Port +None")
try:
    varVlans = regex.findall(varCli_result)
except:
    wf_error("Unexpected CLI response.")
else:
    varX = range (len(varVlans))
    varVlanIDs=[]
    varVlanNames=[]
    for varI in varX:
        varVlanIDs.append(varVlans[varI][0])
        varVlanNames.append(varVlans[varI][1])

    varCMDS = []
    varCMDS.append('configure terminal')

## Get vlans of the uplink switch.

var_query = '''query{network{device(ip: "%s"){deviceData{vlans{name,vid}}}}}''' %varUplink_SW
var_Result = emc_nbi.query(var_query)
vlans_id = var_Result['network']['device']['deviceData']['vlans']

## loop the local vpn and replace name is not correct.

for varVlan in var_Result['network']['device']['deviceData']['vlans']:
        if str(varVlan['vid']) in varVlanIDs:
            if str(varVlan['name']) in varVlanNames:
                varVlanNames.remove(str(varVlan['name']))
                varVlanIDs.remove(str(varVlan['vid']))
            else:
                #vlan name does not match
                if str(varVlan['vid']) != "1":
                    AddCommandChangeVlan (varVlan['name'],varVlan['vid']) 
                    print varCMDS
                    varChanged=True
                del varVlanNames[varVlanIDs.index(str(varVlan['vid']))]
                varVlanIDs.remove(str(varVlan['vid']))

## send commands to the switch.
if varChanged:
    varCli_result = sendConfigCmds(varCMDS)
    emc_results.put("ChangedVlan","true")


print "end"

Thought I shared it with you all

Planning to run this script two times a day to my switches. Or do you see away to run it after a vlan is added to the switch via fa ?

Kind regards

Jay,

What is the target platform?

ERS, VSP or EXOS?
