HP Networking ‘ProCurve’ – Trunking / Aggregating Ports


KB ID 0000638 Dtd 24/07/12


I was lending a hand this week, while my colleague swapped out a lot of switches. I don’t usually deploy a large number of HP switches, so I was surprised when we installed a chassis switch and after patching the fiber links, the Cisco Catalyst switches all got upset and we lost three out of four ping packets.

I (wrongly) assumed that STP would be enabled, so I wandered back and pulled the second fiber link. I knew from conversations I’d had before, that HP call having multiple uplinks between the same switch, to increase throughput "Trunking". (Note: For people like me, who think that switch trunks are links for carrying multiple VLAN traffic. In "HP Land" trunking means aggregating switch uplinks).


Note: Up to four uplinks can be aggregated into one trunk.

Option 1 Configure a Trunk via Telnet/Console Cable

1. Connect to the switch either by Telnet or via the console cable > Log in > type menu {Enter} > The Switch menu will load > Select "2. Switch Configuration…".

2. Port/Trunk Settings.

3. Press {Enter} > Edit >Scroll to the first port you want to add to the trunk > Use the arrow keys to navigate to the "Group" column > Press {Space} > Select the first unused trunk > Arrow to the "Type" column > Change to "Trunk" > Press Enter > Save.

4. Repeat to add the additional "Links", then configure the mirror image on the switch at the other end.

Option 2 Configure a Trunk via the Web / GUI Console

1. Log into the wen console > Interface >Port Info/Config > Select the first link you want to trunk > Change.

2. Set the Trunk Type to "Trunk" > Change the Trunk Group to the next available trunk > Save.
