Hi All,
There is a requirement for me to pick up "device types" of Cisco devices
using SNMP. Could somebody share a OID or direct me to the MIB file that can
help me get this information?
For example, a 2811 polled with this OID should return a value which says
that the device is a "Router".
While I understand that a lot of Cisco modular devices can act as a Switch /
Router / Firewall / Load Balancer based on the modules installed and/or the
IOS running, I just need to get the basic device type. As an example, a
Catalyst 6500 chassis polled with this OID should return something like
"Switch" regardless of the presence of a Firewall Services Module on it.
if you only need to compare between a pure Layer2 or a Layer3 device,
then you could use the following OID:
ipForwarding OBJECT-TYPE
SYNTAX INTEGER {
forwarding(1), -- acting as a gateway
not-forwarding(2) -- NOT acting as a gateway
}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The indication of whether this entity is acting
as an IP gateway in respect to the forwarding of
datagrams received by, but not addressed to, this
entity. IP gateways forward datagrams. IP hosts
do not (except those source-routed via the host).
Note that for some managed nodes, this object may
take on only a subset of the values possible.
Accordingly, it is appropriate for an agent to
return a `badValue' response if a management
station attempts to change this object to an
inappropriate value."
::= { ip 1 }
Example:
snmpget YOUR-SWITCH .1.3.6.1.2.1.4.1.0
IP-MIB::ipForwarding.0 = INTEGER: notForwarding(2)
snmpget YOUR-ROUTER .1.3.6.1.2.1.4.1.0
IP-MIB::ipForwarding.0 = INTEGER: forwarding(1)
