Re: [Netdisco] Juniper devices about 14.x and higher have blank os_ver

[Andy R. <ac...@gm...>]

Ok, that was it.

There is no version info in description(). It's in lldp_sysdesc().

The regexp you're using for description() should be moved to lldp_sysdesc().

I edited Juniper.pm and did a discovery and it worked (it populated
the os_ver field), but I'm not sure if it's going to break other stuff
so I changed it back.

Here's the raw data:

SNMP::Info::_global lldp_sysdesc : LLDP-MIB::lldpLocSysDesc.0 :
.1.0.8802.1.1.2.1.3.4.0
"Juniper Networks, Inc. ex4500-40f , version 12.3R12.4 Build date:
2016-01-20 05:53:00 UTC "

SNMP::Info::_global lldp_sysdesc : LLDP-MIB::lldpLocSysDesc.0 :
.1.0.8802.1.1.2.1.3.4.0
"Juniper Networks, Inc. ex4500-40f Ethernet Switch, kernel JUNOS
15.1R5.5, Build date: 2016-11-25 16:33:55 UTC Copyright (c) 1996-2016
Juniper Networks, Inc."

Shall I open a bug?
