devinodaniel / go-junos Goto Github PK

A Go package that interacts with Junos devices, as well as Junos Space, and allows you to do the following:

• Run operational mode commands, such as show, request, etc..
• Compare the active configuration to a rollback configuration (diff).
• Rollback the configuration to a given state or a "rescue" config.
• Configure devices by submitting commands, uploading a local file or from a remote FTP/HTTP server.
• Commit operations: lock, unlock, commit, commit-at, commit-confirmed, etc.
• Device views - This will allow you to quickly get all the information on the device given a specific view.
• [SRX] Convert from a zone-based address book to a global one.

Junos Space

• Get information from Junos Space managed devices.
• Add/remove devices from Junos Space.
• List all software image packages that are in Junos Space.
• Stage and deploy software images to devices from Junos Space.
• Create, edit and delete address and service objects/groups.
• Edit address and service groups by adding or removing objects to them.
• View all policies managed by Junos Space.
• Publish policies and update devices.
• Add/modify polymorphic (variable) objects.

go get -u github.com/scottdware/go-junos

Note: This package makes all of it's calls over Netconf using the go-netconf package from Juniper Networks. Please make sure you allow Netconf communication to your devices:

set system services netconf ssh
set security zones security-zone <xxx> interfaces <xxx> host-inbound-traffic system-services netconf

Visit the GoDoc page for package documentation and examples.

Connect to a device, and view the current config to rollback 1.

jnpr, err := junos.NewSession("qfx-switch.company.com", "admin", "Juniper123!")
if err != nil {
    fmt.Println(err)
}

defer jnpr.Close()

diff, err := jnpr.Diff(1)
if err != nil {
    fmt.Println(err)
}

fmt.Println(diff)

// Will output the following

[edit vlans]
-   zzz-Test {
-       vlan-id 999;
-   }
-   zzz-Test2 {
-       vlan-id 1000;
-   }

View the routing-instance configuration.

jnpr, err := junos.NewSession("srx.company.com", "admin", "Juniper123!")
if err != nil {
    fmt.Println(err)
}

defer jnpr.Close()

riConfig, err := jnpr.GetConfig("text", "routing-instances")
if err != nil {
    fmt.Println(err)
}

fmt.Println(riConfig)

// Will output the following

routing-instances {
    default-ri {
        instance-type virtual-router;
        interface lo0.0;
        interface reth1.0;
        routing-options {
            static {
                route 0.0.0.0/0 next-hop 10.1.1.1;
            }
        }
    }
}

Device views allow you to quickly gather information regarding a specific "view", so that you may use that information however you wish. A good example, is using the "interface" view to gather all of the interface information on the device, then iterate over that view to see statistics, interface settings, etc.

Note: Some of the views aren't available for all platforms, such as the ethernetswitch and virtualchassis on an SRX or MX.

Current out-of-the-box built-in views are:

• arp: Gathers the ARP table on the device.
  • Same as show arp
• route: Gathers the routing table (for all routing-instances) on the device.
  • Same as show route
• bgp: Gathers information about every BGP peer configured on the device.
  • Same as show bgp summary
• interface: Gathers the interface listing as well as statistics and settings on the device.
  • Same as show interfaces
• vlan: Gathers the VLAN table on the device.
  • Same as show vlans
• ethernetswitch: Gathers the ethernet-switching table on the device.
  • Same as show ethernet-switching table
• inventory: Gathers the physical inventory on the device.
  • Same as show chassis hardware
• virtualchassis: Gathers the virtual-chassis configuration on the device.
  • Same as show virtual-chassis status

You can even create your own views by creating a struct that models the XML output from using the GetConfig() function. Granted, this is a little more work, and requires you to know a bit more about the Go language (such as unmarshalling XML), but if there's a custom view that you want to see, it's possible to do this for anything you want.

I will be adding more views over time, but feel free to request ones you'd like to see by emailing me, or drop me a line on Twitter.

Example: View the ARP table on a device

views, err := jnpr.Views("arp")
if err != nil {
    fmt.Println(err)
}

fmt.Printf("# ARP entries: %d\n\n", views.Arp.Count)
for _, a := range views.Arp.Entries {
    fmt.Printf("MAC: %s\n", a.MACAddress)
    fmt.Printf("IP: %s\n", a.IPAddress)
    fmt.Printf("Interface: %s\n\n", a.Interface)
}

// Will print out the following

# ARP entries: 4

MAC: 00:01:ab:cd:4d:73
IP: 10.1.1.28
Interface: reth0.1

MAC: 00:01:ab:cd:0a:93
