Which device was reporting the -1? Was it the switch or the server?
It is the Zenoss server that is reporting -1
Name ethernet1/1 MAC Address 00:0C:DB:FC:41:00
IP Addresses
Operational Status Up Administrative Status Up
Type Gigabit Ethernet Speed -1
MTU 2000 SNMP Index 1
The switch is a Foundry MLX-8 with a mixture of 10G and 1G optics.
Taking a look again at the snmpwalk it is showing the speed a
little odd as well for the 10G so I guess I'll have to go look into
this a little further at my end.
IF-MIB::ifSpeed.1 = Gauge32: 4294967295
IF-MIB::ifSpeed.2 = Gauge32: 4294967295
Simply because 10G is larger than Gauge32 (which is the type of IF-
MIB::ifSpeed) and therefore won't be displayed correctly; use IF-
MIB::ifHighSpeed to get the correct speed (though you'll have to
write your own InterfaceMap plugin or adjust the one coming with
Zenoss I guess):
ifSpeed OBJECT-TYPE
SYNTAX Gauge32
DESCRIPTION
"An estimate of the interface's current bandwidth in bits
per second. For interfaces which do not vary in bandwidth
or for those where no accurate estimation can be made, this
object should contain the nominal bandwidth. If the
bandwidth of the interface is greater than the maximum
value
reportable by this object then this object should report
its
maximum value (4,294,967,295) and ifHighSpeed must be used
to report the interace's speed. For a sub-layer which has
no concept of bandwidth, this object should be zero."
