NAME
Device::Cisco::NXAPI - Interact with the NX-API (Nexus 9K Switches)
VERSION
Version 0.01
SYNOPSIS
This module provides methods to make API calls and extract information from devices that support the NX-API. This is predominantly the Nexus 9K range of switches in NXOS mode (not in ACI mode).
use Device::Cisco::NXAPI;
my $switch_api = Device::Cisco::NXAPI->new(uri => "https://192.168.1.1:8080", username => "admin", password => "admin");
my @route_info = $switch_api->routes(vrf => "CustVRF");
my %version_info = $switch_api->version();CONSTRUCTOR
This method constructs a new Device::Cisco::NXAPI object.
my $switch_api = Device::Cisco::NXAPI->new(
# Mandatory parameters:
uri => '', # URI of the switch to connect to.
username => '', # Username to logon to the switch
password => '', # Password to logon to the switch
# Optional Parameters
debug => (0 | 1), # Output debugging information to stderr
);METHODS
tester()
Returns a Device::Cisco::NXAPI::Test object for the switch. This object can be used to run test cases against the switch.
version()
my %version_info = $switch->version()Returns a hash consisting of system information. There are no arguments to this method.

);routes( %options )
my @routes = $switch->routes(
vrf => '',
af => 'ipv4 | ipv6',
);
my $first_route = $routes[0]->{prefix};Returns a list of HASHREFs with information on the routes present in the a VRFs routing table. The 'vrf =>' argument determines the VRF, and if not specified the global routing table is used. The 'vrf => all' will return routes from all routing tables on the switch.
The structure returned is as follows:
(
{
'prefix' => '1.1.1.0/24' # The prefix of the route
'vrf' => 'other_vrf', # VRF the route is in.
'paths' => [ # Paths to next-hop (multiple paths in the case of ECMP)
{
'clientname' => 'direct', # Protocol (e.g. direct, local, static, ospf)
'uptime' => 'P28DT19H43M28S', # Time the route has been in the routing table
'ipnexthop' => '2.2.2.1', # Next hop IP for the path
'ifname' => 'Eth1/1' # Egress interface for the path
}
],
},
)arp( %options )
my @arp_table = $switch->arp(
vrf => '',
);Returns a list of HASREFs containing the ARP table information. The vrf argument specifies the VRF to retrieve the ARP entries from. If no argument is specified the global routing table is used. If all is specified as the VRF, ARP entries from all routing tables are returned.
The structure returned is as follows:
(
{
'ifname' => 'mgmt0', # Egress interface
'vrf' => 'management', # VRF
'mac' => '0009.0fe9.9b39', # MAC address
'ip' => '10.47.64.4', # IP address
'time-stamp' => '00:01:20' # Entry timeout
}
)vlans()
my @vlan_info = $switch->vlans();Returns a list of HASHREFs containing information on the current layer 2 VLANs configured on the device. This method has no arguments.
The data structure returned is as follows:
(
{
'id' => '1',
'utf_id' => '1',
'name' => 'default',
'admin_state' => 'noshutdown',
'vlan_state' => 'active'
'interfaces' => [
'Ethernet1/3-22',
'Ethernet1/26-44',
'Ethernet1/47-54'
],
},
)physical_interfaces()
my @interface_info = $switch->physical_interfaces(); Returns a list of HASHREFs containing information on the physical interfacee state.
The structure returned is as follows:
