Re: [torrus-users] can't parse snmp-output from netgear switch

[Stanislav S. <ssi...@ya...>]

actually writing the config manually is not a big deal.
Anyway from that snmpwalk that you've sent, there's no information about 
port names or numbers, so probably manual work is the easiest thing to do.

Point Devdiscover to some other device, like cisco router, 
and set these two parameters in DDX:
only-devtypes -> "RFC2863_IF_MIB"
RFC2863_IF_MIB::ifindex-map-hint -> ifIndex


then you'll have a good XML to start with. Then just replace the host IP address
and play with the interfaces on your Netgear.

If you have many such switches, you can create a custom template for Netgear switches
from this XML.
