Hi,

Can someone please clarify the setup for a virtualbox environment with trex. I cannot get packets to loop back to trex receive port. Not sure how this will forward if I cannot populate ARP entries for at least the gateway, do I need to assign IP's on the Trex interfaces?

Hi,

You will need to add static arp in both direction for the TRex interfaces MAC (for next hope IP).

See the manual for ASR1k configuration guidelines.

We plan to solve this in the next releases.

Thanks,

Hanoh

Thanks for the help and reply, following is the config which worked for me. Main thing was the static ARP and dummy IP's pointing to Trex interfaces:

VirtualBox Trex config

-----------| |-------------------|

Trex client-MAC01---trex-intnet---MAC03-Ubuntu-enp0s8 |

| | | |

Trex Server-MAC02----intnet-------MAC04-Ubuntu-enp0s9 |

| | | |

-----------| |-------------------|

MAC01: [0x08,0x00,0x27,0x8e,0xfc,0x42] IP: N/A

MAC02: [0x08,0x00,0x27,0x23,0x21,0xdc] IP: N/A

MAC03: [0x08,0x00,0x27,0x81,0x6d,0xe0] IP: 192.168.1.100 Int: enp0s8

MAC04: [0x08,0x00,0x27,0x81,0xf6,0x63] IP: 192.168.2.100 Int: enp0s9

Trex server

=============

+ Trex configuration is the same as the standard test config found at: https://trex-tgn.cisco.com/trex/doc/trex_vm_manual.html

+ Make sure the two interfaces you have for the internal VM network match the ones configured for Ubuntu server [trex_intnet / intnet]

+ Confirm the ARP entires on the Ubuntu server match the Trex VM

+ Confirm the MAC details of the Yaml test file OR the

[trex@localhost etc]$ more trex_cfg.yaml

Ubuntu Server

===============

+ Add two interfaces to the VirtualBox VM, each with adapter type of 'server'

+ Place each one in a separate VLAN [trex_intnet / intnet]

+ Configure the interfaces with an IP on separate subnets

+ Add the static routes for relevant pcap tests being run from Trex [eg; 16.0.0.0 and 48.0.0.0]. Route to dummy IP towards Trex

+ Add the static ARP entires for next hop per interface to the dummy IP

Configure the interfaces with an IP on separate subnets

Add the static routes for relevant pcap tests being run from Trex [eg; 16.0.0.0 and 48.0.0.0]. Route to dummy IP towards Trex
