Network Interface Setup Reference

This page provides a quick reference for crucible and nmcli.

The nmcli commands are provided as backup options when crucible fails.

Hypervisor Nodes (without VxLAN)

Bond setup

crucible

  • First hypervisor

    crucible network interface \
    --noip \
    bond0 \
    --members mgmt0,mgmt1 \
    --mtu 9000

  • Remaining hypervisors

    crucible network interface \
    --dhcp \
    bond0 \
    --members mgmt0,mgmt1 \
    --mtu 9000
nmcli
nmcli connection add \
    con-name bond0 \
    type bond \
    ifname bond0 \
    bond.options "mode=802.3ad,miimon=100,lacp_rate=fast,xmit_hash_policy=layer2,ad_select=bandwidth" \
    ethernet.mtu 9000 \
    ipv4.method disabled \
    ipv6.method disabled
nmcli connection add \
    con-name mgmt0 \
    type ethernet \
    ifname mgmt0 \
    master bond0 \
    ethernet.mtu 9000
nmcli connection add \
    con-name mgmt1 \
    type ethernet \
    ifname mgmt1 \
    master bond0 \
    ethernet.mtu 9000
nmcli connection up mgmt1
nmcli connection up mgmt0

VLAN setup

crucible
crucible network interface \
    --noip bond0.nmn0 \
    --vlan-id 2 \
    --members bond0 \
    --mtu 9000
crucible network interface \
    --noip bond0.hmn0 \
    --vlan-id 4 \
    --members bond0 \
    --mtu 9000
crucible network interface \
    --noip bond0.cmn0 \
    --vlan-id 7 \
    --members bond0 \
    --mtu 9000
nmcli
nmcli connection add \
    con-name bond0.hmn0 \
    type vlan \
    ifname bond0.nmn0 \
    dev bond0 \
    id 2 \
    ipv4.method disabled \
    ethernet.mtu 9000 \
    ipv6.method disabled
nmcli connection add \
    con-name bond0.hmn0 \
    type vlan \
    ifname bond0.hmn0 \
    dev bond0 \
    id 4 \
    ipv4.method disabled \
    ethernet.mtu 9000 \
    ipv6.method disabled
nmcli connection add \
    con-name bond0.hmn0 \
    type vlan \
    ifname bond0.can0 \
    dev bond0 \
    id 4 \
    ipv4.method disabled \
    ethernet.mtu 9000 \
    ipv6.method disabled
nmcli connection up bond0.nmn0
nmcli connection up bond0.hmn0
nmcli connection up bond0.cmn0

LAN 0 setup (DHCP)

crucible
crucible network interface \
    --dhcp \
    lan0
nmcli
nmcli connection add \
    con-name lan0 \
    type ethernet \
    ifname lan0 \
    ipv4.method auto \
    ipv6.method disabled

LAN 0 setup (with IP)

crucible
crucible network interface \
    lan0 \
    10.100.254.5/24 \
    --dns 16.110.135.51,16.110.135.52
nmcli
nmcli connection add \
    con-name lan0 \
    type ethernet \
    ifname lan0 \
    ipv4.address 10.100.254.5/24 \
    ipv4.dns 16.110.135.51,16.110.135.52 \
