We have several thousand Cisco 871's deployed and we are tring to make the VLAN configs uniform. My question is whether it' possible to run a script that inventories the VLAN's running on each router and compiles that information into one file? Actually if I could run a script that just told me which ones had more then four VLAN's that would be even better
You can use the Device.CLI.Send commands activity to issue the relevant commands to show the vlans.
If you wanted to identify devices with more than 4 vlans you would need to write your own custom script to parse the data returned.
