SYNOPSIS
my $sonmp = new SNMP::Info (
AutoSpecify => 1,
Debug => 1,
DestHost => 'router',
Community => 'public',
Version => 2
);
my $class = $sonmp->class();
print " Using device sub class : $class\n";
$hascdp = $sonmp->hasCDP() ? 'yes' : 'no';
# Print out a map of device ports with CDP neighbors:
my $interfaces = $sonmp->interfaces();
my $c_if = $sonmp->c_if();
my $c_ip = $sonmp->c_ip();
my $c_port = $sonmp->c_port();
foreach my $cdp_key (keys %$c_ip){
my $iid = $c_if->{$cdp_key};
my $port = $interfaces->{$iid};
my $neighbor = $c_ip->{$cdp_key};
my $neighbor_port = $c_port->{$cdp_key};
print "Port : $port connected to $neighbor / $neighbor_port\n";
}
DESCRIPTIONSNMP::Info::SONMP is a subclass of SNMP::Info that provides an object
oriented interface to the SynOptics Network Management Protocol (SONMP)
information through SNMP.
SONMP is a Layer 2 protocol that supplies topology information of
devices that also speak SONMP, mostly switches and hubs. SONMP is
implemented in SynOptics, Bay, and Nortel devices. SONMP has been
rebranded by Bay then Nortel and is know by several different names,
most recently Nortel Discovery Protocol (NDP).
Create or use a device subclass that inherits this class. Do not use
directly.
Each device implements a subset of the global and cache entries. Check
the return value to see if that data is held by the device.
Inherited Classes
None.
Required MIBs
SYNOPTICS-ROOT-MIB
S5-ETH-MULTISEG-TOPOLOGY-MIB
GLOBAL METHODS
These are methods that return scalar values from SNMP
$sonmp->index_factor()
Returns a number representing the number of ports reserved per slot
or switch within the device MIB. Defaults to 32.
$sonmp->slot_offset()
Returns the offset if slot numbering does not start at 0. Defaults
to 1.
$sonmp->port_offset()
Returns the offset if port numbering does not start at 0. Defaults
to 0.
$cdp->hasCDP()
Is SONMP is active in this device?
$sonmp->cdp_id()
Returns the IP that the device is sending out for its Nmm topology
info.
("s5EnMsTopIpAddr")
$sonmp->cdp_run()
Returns true if SONMP is on for this device.
("s5EnMsTopStatus")
$sonmp->mac()
Returns MAC of the advertised IP address of the device.
TABLE METHODS
These are methods that return tables of information in the form of a
reference to a hash.
Layer2 Topology info ("s5EnMsTopNmmTable")
$sonmp->sonmp_topo_slot()
Returns reference to hash. Key: Table entry, Value:slot number
("s5EnMsTopNmmSlot")
$sonmp->sonmp_topo_port()
Returns reference to hash. Key: Table entry, Value:Port Number
(interface iid)
("s5EnMsTopNmmPort")
$sonmp->sonmp_topo_ip()
Returns reference to hash. Key: Table entry, Value:Remote IP
address of entry
("s5EnMsTopNmmIpAddr")
$sonmp->sonmp_topo_seg()
Returns reference to hash. Key: Table entry, Value:Remote Segment
ID
("s5EnMsTopNmmSegId")
$sonmp->sonmp_topo_mac()
("s5EnMsTopNmmMacAddr")
Returns reference to hash. Key: Table entry, Value:Remote MAC
address
$sonmp->sonmp_topo_platform
Returns reference to hash. Key: Table entry, Value:Remote Device
Type
("s5EnMsTopNmmChassisType")
$sonmp->sonmp_topo_localseg
Returns reference to hash. Key: Table entry, Value: Boolean, if
bay_topo_seg() is local.
("s5EnMsTopNmmLocalSeg")
Pseudo CDP information
All entries with port=0 are local and ignored.
$sonmp->c_if()
Returns reference to hash. Key: IID, Value: Local port
(interfaces)
$sonmp->c_ip()
Returns reference to hash. Key: IID, Value: Remote IP address
If multiple entries exist with the same local port, c_if(), with
different IPv4 addresses, c_ip(), there is either a non SONMP
device in between two or more devices or multiple devices which are
not directly connected.
Use the data from the Layer2 Topology Table below to dig deeper.
$sonmp->c_port()
Returns reference to hash. Key: IID, Value: Remote port
(interfaces)
$sonmp->c_platform()
Returns reference to hash. Key: IID, Value: Remote device type
