• HPE 5510 48G 4SFP+ HI 1-slot Switch - LACP configuration assistance

I want to configure a ‘trunk’ of 4 ports using the LACP protocol in HP5510-48G comware switch for load sharing.

 

I found that Bridge-Aggregation is used in A5500-48G( comware ) , instead of LACP in Hp Procurve.

 

Could you please confirm this for me ?

Hi @MohanBabu2287 !

I am afraid you are mixing things here. 'Trunk" in ProCurve is 'Bridge-Aggregation' or 'BAGG' in Comware. BAGGs can be static or dynamic. 'Dynamic' means LACP is used to negotiate an aggregation. So, if on ProCurve side you have trunk with LACP, then on Comware side you need:

inteface Bridge-Aggregation1
 link-aggregation mode dynamic

Thanks. I got the answer now, I will use dynamic in Bridge Agg to use LACP.

Is it necessary to disable the STP in the physical interface while creating LACP  like below

 

interface GigabitEthernet1/0/48
port link-mode bridge
description Connection to XXXXXX
port link-type trunk
port trunk permit vlan 1
stp disable
port link-aggregation group 2

If you have STP running on ProCurve side, leave it enabled on the 5510 as well. STP doesn't interfere with LACP and won't cause any issues negotiating the aggragation.

Re: • HPE 5510 48G 4SFP+ HI 1-slot Switch - LACP configuration assistance

But i am connecting server with  stack switch(4) of 5510 in which STP enabled . Will it STP block the ports in bride Agg if not disabled ?

Configuration blow,

interface Bridge-Aggregation 3
port link-type trunk
port trunk permit vlan 1
link-aggregation mode dynamic


1. Create the link aggregation interface
2. Associate the member ports to the aggregation interface
3. Make any additional changes to the link aggregation

Step 1: Create the link aggregation and set the mode to dynamic (LACP)

[Rack4sw1]interface Bridge-Aggregation 3
[Rack4sw1-Bridge-Aggregation3] link-aggregation mode dynamic

Step 2: Associate the the member ports

interface GigabitEthernet 1/0/46
[GigabitEthernet1/0/46]port link-aggregation group 3

interface GigabitEthernet 2/0/46
[GigabitEthernet2/0/46]port link-aggregation group 3

interface GigabitEthernet 3/0/46
[GigabitEthernet3/0/46]port link-aggregation group 3

interface GigabitEthernet 4/0/46
[GigabitEthernet4/0/46]port link-aggregation group 3

Step 3: set the port link type to trunk and permit vlans

[Rack4sw1]interface Bridge-Aggregation 3
[Rack4sw1-Bridge-Aggregation12]port link-type trunk
[Rack4sw1-Bridge-Aggregation12]port trunk permit vlan 1

No, STP will not block a port that is connected to a server that doesn't speak STP. In order to speed up connectivity to such server, use "stp edge-port" command on all ports and/or aggregations that are connected to servers, hosts and other non-STP devices.
