HP 5820 LACP (802.3ad) with non-HP (Cisco, F5 and others)

HP 5820-24XG-SFP+ is a 24 port 10GB SFP+ Layer 3 enterprise and carrier grade Ethernet switch. This is running Comware5 network operating system. This switch is actually manufactured by H3C.

HP 5820 series LACP (802.3ad) link aggregation is called “Bridge-Aggregation” interface. The configuration is pretty much similar to Cisco EtherChannel.

I will discuss two things here–

(a). how to configure link-aggregation between HP and non-HP (Cisco, F5, Juniper) devices.

(b). how to configure link-aggregation between HP and HP (HP ProCurve ProVision, Comware5/7, HP SAN).

Following are configuration commands to create LACP between HP and non-HP devices –

(a). Enter the following command on the HP switch to create bridge-aggregation interface

(trunk/tagged vlan interface example)

interface Bridge-Aggregation1
 description “LACP Trunk goes to a non-HP device”
 port link-type trunk
 port trunk permit vlan all ;this can be limited to user define VLANs only 
 link-aggregation mode dynamic  ;for non-HP mode dynamic is require

(access port example)

interface Bridge-Aggregation2
 description “LACP access goes to a non-HP device”
 port access vlan 100
 link-aggregation mode dynamic  ;for non-HP mode dynamic is require

After define bridge aggregation interface – you need to add physical interfaces to it. Physical interface should inherit all the parameters configured on the bridge-aggregation interface.

Make sure physical interfaces are configured with “default” settings only before put them to a bridge-aggregation group to get settings auto inherited. Otherwise you need to specify “link-type” and “permit vlan” parameters once again on all the member physical interfaces.

interface Ten-GigabitEthernet1/0/22
   port link-mode bridge
   description “this interface is a member of bridge-aggregation 1”
   port link-type trunk
   port trunk permit vlan all
   port link-aggregation group 1

interface Ten-GigabitEthernet2/0/22
   port link-mode bridge
   description “this interface is a member of bridge-aggregation 1”
   port link-type trunk
   port trunk permit vlan all
   port link-aggregation group 1

Once done – you should be able to see aggregated bandwidth on the “Bridge-Interface”.

Do a “#display interface Bridge-Aggregation 1

(b). For LACP between HP and HP devices enter all the above commands except “link-aggregation mode dynamic”.
