Network Diagnostics

This section covers network troubleshooting tools available in FloofOS, including ping and traceroute.

Overview

FloofOS provides built-in network diagnostic tools that operate directly through VPP. These commands can be executed from both operational mode and configuration mode.

Ping

Description

The ping command sends ICMP echo requests to test connectivity. Ping is handled directly by VPP for accurate dataplane testing.

Syntax

ping {<ip-addr> | ipv4 <ip4-addr> | ipv6 <ip6-addr>} [ipv4 <ip4-addr> | ipv6 <ip6-addr>] [source <interface>] [size <pktsize:60>] [interval <sec:1>] [repeat <cnt:5>] [table-id <id:0>] [burst <count:1>] [verbose]

Common Parameters

Parameter Description Default
source <interface> Source interface Auto
size <pktsize> Packet size in bytes 60
interval <sec> Interval between pings 1
repeat <cnt> Number of pings 5
table-id <id> VRF/routing table ID 0
burst <count> Burst count 1
verbose Verbose output Off

Examples

# Basic ping
ping 172.16.32.1

# Ping from specific interface
ping 192.168.1.1 source GE1/0/0

# Custom count and size
ping 10.0.0.1 repeat 10 size 1400

Error Messages

Message Meaning
Failed: no egress interface No route to destination (missing gateway)
Request timeout ICMP request timed out

No Egress Interface

If you receive "no egress interface" errors, verify that a default gateway is configured. This can be set via BGP or static routes in the global-config section of BGP configuration.

Traceroute

Description

The traceroute command traces the path packets take to reach a destination.

Syntax

traceroute <address> [asn | source <ip> | interface <interface>]

Parameters

Parameter Description
address Destination IP address or hostname
asn Display ASN information for each hop
source <ip> Source IP address
interface <interface> Source interface

Examples

# Basic traceroute
traceroute 172.16.32.1

# Traceroute with ASN display
traceroute 1.1.1.1 asn

# Traceroute from specific source
traceroute 8.8.8.8 source 10.0.0.1

ASN Lookup Requirement

The asn option requires a working default route. Configure a gateway via BGP or static routes in the global-config section of BGP configuration.

Troubleshooting Guide

Connectivity Issues

Symptom Possible Cause Resolution
"no egress interface" No default route Configure BGP or static gateway
"Network is unreachable" No route to network Verify routing configuration
Request timeout Firewall/ACL blocking Check firewall rules
High latency Network congestion Check interface traffic

Verifying Routes

Before running diagnostics, verify routing:

show configuration

Look for: - Interface IP addresses - BGP peer configuration - Static routes in global-config
