topic UpIntfName DB variable for sub-interfaces in Controllers https://community.cisco.com/t5/controllers/upintfname-db-variable-for-sub-interfaces/m-p/3506052#M1402 <HTML><HEAD></HEAD><BODY><P>Just a note in case anyone else stumbles upon this and gets as confused as I did: there is a discrepancy between how the UpIntfName DB variable handles sub-interfaces and how routers/switches handle them. UpIntfName selects interfaces that don't have 'shutdown' in their config. For example:</P><P></P><P>interface gi0/0</P><P> description physical interface</P><P> shutdown</P><P>interface gi0/0.10</P><P> description sub-interface</P><P> no shut</P><P></P><P>With the above configuration a 'sh int desc' on the router will show the sub-interface as being 'admin down' because it's parent physical interface is shutdown. However, UpIntfName will include the sub-interface in any templates you deploy. To correctly exclude the sub-interfaces from UpIntfName you have to enter the shutdown command on each of them (and probably re-sync the device in Prime). Was getting confused as the show commands on the router said the subs were shut and it was only when I looked at 'show run int' that I noticed they're actually not.</P><P></P><P>Anyway, its not a bug or problem, just thought I'd mention it, hope that helps anyone who comes across it.</P><P></P><P>Dave</P></BODY></HTML> Tue, 29 Nov 2016 10:32:32 GMT Dave Lewis 2016-11-29T10:32:32Z UpIntfName DB variable for sub-interfaces https://community.cisco.com/t5/controllers/upintfname-db-variable-for-sub-interfaces/m-p/3506052#M1402 <HTML><HEAD></HEAD><BODY><P>Just a note in case anyone else stumbles upon this and gets as confused as I did: there is a discrepancy between how the UpIntfName DB variable handles sub-interfaces and how routers/switches handle them.
