  • 1.  HP 2920 LACP Trunk Problems.

    Posted Nov 14, 2013 01:47 PM

    Hello I seem to be having problems with a lacp trunk on an hp 2920.  When both connections are connected the switch no longer passes traffic.   My core is two hp 5900 series switches in IRF That is configured with a bridge aggregation with link aggregation dynamic 

     

    HP2920 Config - Trk2 is my uplink to my Core. Trk1 goes to the endpoint switch. 

    Running configuration:
    
    ; J9729A Configuration Editor; Created on release #WB.15.11.0007
    ; Ver #03:12.15.0d:09

     HP 5900 Snippet of code for the Edge switch. 

    interface Bridge-Aggregation5
     description ACF 4th Floor 
     port link-type trunk
     port trunk permit vlan all
     link-aggregation mode dynamic
    
    interface Ten-GigabitEthernet1/0/40
     description "ACF 4th Floor A1"
     port link-type trunk
     port trunk permit vlan all
     port link-aggregation group 5
    
    interface Ten-GigabitEthernet2/0/40
     description "ACF 4th Floor A2"
     port link-type trunk
     port trunk permit vlan all
     port link-aggregation group 5

     I cannot understand why this is not working as it should.  Any help is appreciated. 

     

    Thank You

    I couldn't get Procurve/H3C to work with LACP/dynamic. I got sick of fiddling with it and just set the procurve to "trunk", took the "Dynamic" off the H3C bridge-aggregation interface. Works fine.

    Vince, Would this still give me a 20gb bond?  I thought Trunk would give me a active/standby configuration for failover where as lacp would give me an active active bond turning my two 10gb uplinks into a single 20gb back to my IRF configuration.

    No, it gives you Active/Active.

    Thank You.  I will try this during our next downtime windows.

    Looks like your sample configs should work. I have much the same and they all work.
