Trunk + LACP Link

harrisgirls · ‎07-11-2011

Hi,

I thought i would post here as I know people reply and get good answers!

Its HP ProCurve related.............I have a 5406zl and a 2510G, from the 2510G I have 2x 1Gb Copper Links connecting to the core, I want to create a trunk + lacp with these 2 connections, but when I input "trunk e23,e24 Trk2 LACP" on the core and place into the correct VLAN thats fine then.......

I input "trunk 45-48 Trk2 LACP" onto the 2510G - I cant ping the swich anymore!

I do a wr mem, reload switch but cant ping anything, im missing something here........

Am I doing anything wrong here?

Hi,

I have mentioned below a sample Lacp configuration between cisco device and HP procurve.


switch(config-if)#sh run int g1/0/8

Building configuration...

Current configuration : 304 bytes

!
interface GigabitEthernet1/0/8   description test   switchport trunk encapsulation dot1q   switchport trunk native vlan 60   switchport trunk allowed vlan 3-5,60,88,251   switchport mode trunk   speed 1000   duplex full   no cdp enable   channel-group 10 mode active  end    switch(config-if)#sh run int g1/0/9  Building configuration...    Current configuration : 304 bytes  !  interface GigabitEthernet1/0/9   description RCDC-FS-CS18 [RC-B1-CR-7-D] (etherchannel)   switchport trunk encapsulation dot1q   switchport trunk native vlan 60   switchport trunk allowed vlan 3-5,60,88,251   switchport mode trunk   speed 1000  duplex full   no cdp enable   channel-group 10 mode active    HP Procurve setup ===================   interface F1     name "To RCDC-FS-C301 G1/0/8"     lacp Passive  exit  interface F2     name "To RCDC-FS-C301 G1/0/9"     lacp Passive

++ A port in the passive mode cannot form an Ether Channel with another port that is also in the passive mode because neither port starts LACP negotiation.

++ Have we configured lacp mode as active either in the cisco side or in the HP side ?

Hope this helps

Thanks
