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
