I have a half-working Cisco CSM module for genDevConfig - the CSM indexes t=
he same way - ie with strings encoded as ASCII OIDs.=0A=0AThe CSS module (w=
hich was written long ago) writes out the OIDs in full which is not particu=
larly readable nor clever. For the CSM module (which I started much later) =
I tried a different route - I added a perl subroutine ascii2oid("string") t=
o Cricket so that it was possible to use config like...=0A=0Atarget ...=0A =
...=0A module =3D 4=0A inst =3D %module%.ascii2oid("ws2-public").8=
0=0A=0Awith cricket being such a hack, syntactically it wasn't quite that s=
traight forward but it was certainly much easier to read the configurations=
. The associated CSM module then wrote out configs using the ascii2oid.=0A=
=0AI can dig up the subroutine and some examples if anyone is interested bu=
t I don't have a CSM to develop against anymore. =0A=0ACheers=0A=0A=0A-----=

those are easy to map out but what got me =0Awas that you can't use multipl=
