       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(...);

   Inherited Classes

   Required MIBs
       Inherited Classes' MIBs
           See "Required MIBs" in SNMP::Info::Layer3::CiscoSwitch for its own MIB requirements.


       These are methods that return a scalar value from SNMP

           Returns 'nx-os'

           Returns operating system version extracted from "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.


       IP Address Table

       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,, 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

           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.

       These are methods that return tables of information in the form of a reference to a hash.
