SNMP::Info::Layer3::Nexus - SNMP Interface to Cisco Nexus Switches running NX-OS
# 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(...);
See "Required MIBs" in SNMP::Info::Layer3::CiscoSwitch for its own MIB requirements.
These are methods that return a scalar value from SNMP
Returns operating system version extracted from
Returns the serial number of the chassis from ENTITY-MIB.
Tries to reference $nexus->id() to CISCO-ENTITY-VENDORTYPE-OID-MIB
'cevChassis' for readability.
Each entry in this table is an IP address in use on this device. Some versions do not index the table with the IPv4 address in accordance with the MIB definition, these overrides correct that behavior.
Also, the table is augmented with IP addresses in use by UDP sockets on the device, as determined by checking RFC1213-MIB::udpLocalAddress. Valid addresses from this table (any IPv4 that is not localhost, 0.0.0.0, Class D (multicast) or Class E (experimental) are added as a /32 on interface ID 0. This is a workaround to determine possible VPC Keepalive IP addresses on the device, which are probably advertised by CDP/LLDP to neighbors.
Maps the IP Table to the IID
Maps the Table to the IP address
Gives netmask setting for IP table entry.
Gives broadcast address for IP table entry.
