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(...);

GLOBALS

These are methods that return a scalar value from SNMP

$nexus->vendor()

Returns 'cisco'

$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

$nexus->cisco_comm_indexing()

Returns 1. Use vlan indexing.

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.

$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)
