NAME
       SNMP::Info::Layer3::Nexus - SNMP	Interface to Cisco Nexus Switches
       running NX-OS

AUTHOR
       Eric Miller

SYNOPSIS
	# 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";

DESCRIPTION
       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
       SNMP::Info::Layer3::CiscoSwitch

   Required MIBs
       CISCO-ENTITY-VENDORTYPE-OID-MIB
       CISCO-CONTEXT-MAPPING-MIB
       Inherited Classes' MIBs
	   See "Required MIBs" in SNMP::Info::Layer3::CiscoSwitch for its own
	   MIB requirements.

GLOBALS
       These are methods that return a scalar value from SNMP

       $nexus->os()
	   Returns 'nx-os'

       $nexus->os_ver()
	   Returns operating system version extracted from "sysDescr".

       $nexus->serial()
	   Returns the serial number of	the chassis from ENTITY-MIB.

       $nexus->model()
	   Tries to reference $nexus->id() to CISCO-ENTITY-VENDORTYPE-OID-MIB

	   Removes 'cevChassis'	for readability.

       $nexus->mac()
	   "dot1dBaseBridgeAddress"

   Overrides
       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,
       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.

       $nexus->ip_index()
	   Maps	the IP Table to	the IID

	   ("ipAdEntIfIndex")

       $nexus->ip_table()
	   Maps	the Table to the IP address

	   ("ipAdEntAddr")

       $nexus->ip_netmask()
	   Gives netmask setting for IP	table entry.

	   ("ipAdEntNetMask")

       $nexus->ip_broadcast()
	   Gives broadcast address for IP table	entry.

	   ("ipAdEntBcastAddr")

       reference to a hash.
