The specific error I'm getting is "banner syntax error" from the debug output in CatTools. However, if I run the same job and only include routers, it runs and finishes correctly. Any suggestions? All routers tested are "cisco.router.general" type and the switch is "cisco.switch.ios" type.
Can you check the IOS version on the device(s) having issues please?
If it happens to be IOS 12.2(52)SE, then you may need to try the revised script which is posted in the following thwack thread: Activity Device.Update.Banner (Login) fails with Cisco IOS Version 12.2(52)SE
Let me know how you get on.
