I need to setup distributed trunking next week at a site, and I have not done this before. I need to get this done during some scheduled downtime so need to make sure I've got this right in my head :-)
I am planning to link two E3500's together using 2x 1Gb fiber links (ports 47 and 48). The distributed trunks will be for connecting servers to these switches. Each trunk will have one link to each switch. There will be other switches in this stack but they will not setup for DT or ISC so I assume they are not relevant.
For the ISC setup I think I need these commands...
ProCurve Switch 1(config)# trunk 47-48 trk1 lacp
ProCurve Switch 1(config)# switch-interconnect trk1
ProCurve Switch 2(config)# trunk 47-48 trk1 lacp
ProCurve Switch 2(config)# switch-interconnect trk1
I have read somewhere that I need to setup a peer-keepalive link on a separate VLAN. I assume that I create a new VLAN on each switch (let's say VLAN10) and give the VLAN interfaces IP addresses for example 10.0.0.1 and 10.0.0.2
Then I think I just use these commands to enable the keepalive (not sure if I have to do it on both switches but I assume so)...
ProCurve Switch 1(config)# distributed-trunking peer-keepalive destination 10.0.0.2 source 10.0.0.1 vlan 10 interval 1000 timeout 5 hold-timer 6 udp-port 6400
ProCurve Switch 2(config)# distributed-trunking peer-keepalive destination 10.0.0.1 source 10.0.0.2 vlan 10 interval 1000 timeout 5 hold-timer 6 udp-port 6400
Then lastly to setup the distributed trunk (trk2) to connect a server to port 7 on each switch, I would do the following...
ProCurve Switch 1(config)# trunk 7 trk2 dt-lacp
ProCurve Switch 2(config)# trunk 7 trk2 dt-lacp
Please can someone confirm the above is correct. Not got the hardware to test it here so need some reassurance :-)
