SNMP::Info::Layer3::Nexus - SNMP Interface to Cisco Nexus Switches running NX-OS
Eric Miller
# Let SNMP::Info determine the correct subclass for you. my $nexus = new SNMP::Info( AutoSpecify => 1, Debug => 1, # These arguments are passed directly to SNMP::Session DestHost => 'myswitch', Community => 'public', Version => 2 ) or die "Can't connect to DestHost.\n"; my $class = $nexus->class(); print "SNMP::Info determined this device to fall under subclass : $class\n";
Abstraction subclass for Cisco Nexus Switches running NX-OS.
For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.
my $nexus = new SNMP::Info::Layer3::Nexus(...);

These are methods that return a scalar value from SNMP
Returns 'cisco'
Returns 'nx-os'
Returns operating system version extracted fron sysDescr.
sysDescr
Returns the serial number of the chassis from ENTITY-MIB.
Tries to reference $nexus->id() to CISCO-ENTITY-VENDORTYPE-OID-MIB
Removes 'cevChassis' for readability.
dot1dBaseBridgeAddress
Returns 1. Use vlan indexing.

These are methods that return tables of information in the form of a reference to a hash.
Based upon the firmware version Cisco devices may support Link Layer Discover Protocol (LLDP) in addition to the Cisco-proprietary CDP. These methods will query both and return the combination of all information. As a result, there may be identical topology information returned from the two protocols causing duplicate entries. It is the calling program's responsibility to identify any duplicate entries and remove duplicates if necessary.
Returns true if the device is running either CDP or LLDP.
Returns reference to hash. Key: iid Value: local device port (interfaces)
Returns reference to hash. Key: iid Value: remote IPv4 address
If multiple entries exist with the same local port, c_if(), with the same IPv4 address, c_ip(), it may be a duplicate entry.
If multiple entries exist with the same local port, c_if(), with different IPv4 addresses, c_ip(), there is either a non-CDP/LLDP 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.
Returns reference to hash. Key: iid Value: remote port (interfaces)
Returns reference to hash. Key: iid Value: string value used to identify the chassis component associated with the remote system.
Returns reference to hash. Key: iid Value: Remote Device Type
