On the host
In /etc/sysconfig/network-scripts:
- ifcfg-bond0
DEVICE="bond0" BOOTPROTO=none IPADDR=192.168.10.135 BROADCAST=192.168.255.255 NETMASK=255.255.0.0 NM_CONTROLLED="no" ONBOOT="yes" USERCTL=no BONDING_MASTER=yes TYPE=Bond BONDING_OPTS="mode=4 miimon=100 lacp_rate=0"
To get second bond interface tagged to vlan 2 (PUB)
vconfig add bond0 2
- ifcfg-bond0.2
DEVICE="bond0.2" BOOTPROTO=none ONPARENT=yes IPADDR=193.58.172.92 BROADCAST="193.58.172.127" NETMASK=255.255.255.128 GATEWAY=193.58.172.2 NM_CONTROLLED="no" ONBOOT="yes" USERCTL=no VLAN=yes
- Aggregate interfaces eth0 and eth1 to the bond:
- ifcfg-eth0
DEVICE="eth0" BOOTPROTO=none NM_CONTROLLED="no" ONBOOT="yes" USERCTL=no MASTER=bond0 SLAVE=yes
- ifcfg-eth1
DEVICE="eth1" BOOTPROTO=none NM_CONTROLLED="no" ONBOOT="yes" USERCTL=no MASTER=bond0 SLAVE=yes
On the switch
We are configuring everything in LACP [<=> mode=4 in MODPROBE_OPTS for bond0]
- Adding the PoX interface on the 10G switch
- Using the interface, create the lacp port first in tab ETH Mgmt, click on Link Aggregation, Provide in the box LAG Interface Number PoX (X a number).
- On tab Ports, click on the port you want to add, select LAG: PoX, LAG mode: active (LACP rate is auto on slow [<=> lacp_rate=0 in MODPROBE_OPTS for bond0] )
- If it does not work and complains about vlans, follow the section Adding a new port to PoX below
- on the switch in CLI:
- the PoX port is going to be in hybrid mode, to have untagged[=access] vlan1 and tagged[=hybrid allowed-vlan] vlan 2 (ex: Po5): [ vlan1 cannot be tagged on the switch ]
melswitch1 [standalone: master] > enable melswitch1 [standalone: master] # config term melswitch1 [standalone: master] (config) # interface port-channel 5 melswitch1 [standalone: master] (config interface port-channel 5) # switchport mode hybrid melswitch1 [standalone: master] (config interface port-channel 5) # switchport access vlan 1 melswitch1 [standalone: master] (config interface port-channel 5) # switchport hybrid allowed-vlan 2
- Adding a new port to PoX (ex: ethernet 1/27)
melswitch1 [standalone: master] (config) # interface ethernet 1/27 melswitch1 [standalone: master] (config interface ethernet 1/27) # switchport mode hybrid melswitch1 [standalone: master] (config interface ethernet 1/27) # switchport access vlan 1 melswitch1 [standalone: master] (config interface ethernet 1/27) # switchport hybrid allowed-vlan 2
then on the interface, add the port to PoX following the previous section.
