28 Abstraction subclass for Cisco Nexus Switches running NX-OS.

30 For speed or debugging purposes you can call the subclass directly, but
31 not after determining a more specific class using the method above.

37
38 Required MIBs
39 CISCO-ENTITY-VENDORTYPE-OID-MIB
40 CISCO-CONTEXT-MAPPING-MIB
41 Inherited Classes' MIBs
42 See "Required MIBs" in SNMP::Info::Layer3::CiscoSwitch for its own
43 MIB requirements.
44
46 These are methods that return a scalar value from SNMP
47
48 $nexus->os()
49 Returns 'nx-os'
50
51 $nexus->os_ver()
52 Returns operating system version extracted from "sysDescr".
53
54 $nexus->serial()
55 Returns the serial number of the chassis from ENTITY-MIB.
56
57 $nexus->model()
58 Tries to reference $nexus->id() to CISCO-ENTITY-VENDORTYPE-OID-MIB
59
60 Removes 'cevChassis' for readability.
61
62 $nexus->mac()
63 "dot1dBaseBridgeAddress"
64
65 Overrides
66 IP Address Table
67
68 Each entry in this table is an IP address in use on this device. Some
69 versions do not index the table with the IPv4 address in accordance
70 with the MIB definition, these overrides correct that behavior.
71
72 Also, the table is augmented with IP addresses in use by UDP sockets on
73 the device, as determined by checking RFC1213-MIB::udpLocalAddress.
74 Valid addresses from this table (any IPv4 that is not localhost,
75 0.0.0.0, Class D (multicast) or Class E (experimental) are added as a
76 /32 on interface ID 0. This is a workaround to determine possible VPC
77 Keepalive IP addresses on the device, which are probably advertised by
78 CDP/LLDP to neighbors.
79
80 $nexus->ip_index()
81 Maps the IP Table to the IID
82
83 ("ipAdEntIfIndex")
84
85 $nexus->ip_table()
86 Maps the Table to the IP address
87
88 ("ipAdEntAddr")
89
90 $nexus->ip_netmask()
91 Gives netmask setting for IP table entry.
92
93 ("ipAdEntNetMask")
94
95 $nexus->ip_broadcast()
96 Gives broadcast address for IP table entry.
97
98 ("ipAdEntBcastAddr")
