HP ProCurve 6600 Distributed Trunking

[Deshawn]

I have two HP ProCurve 6600 switches setup and it was ISC link among them plus a peer-keepalive link between them. I have two server which NIC connected with the one switches, one NIC connected to the other switch and links from the server to the switches is dt-lacp links . now on the ISC link and the Peer link are connected both switches can ping both servers . and if ISC link goes down the DT primary is able to ping the both servers although the DT secondary switch stop it's DT trunk and if the both the ISC as well as the peer link goes down then the primary DT Switch is able to still ping the servers however the secondary DT switch Is not able to ping . now as far as I know when 1 of the switches losses the ISC and Peer link , it does not recognize is it which other switch is doing so they must together can ping the servers , but in my case the secondary cannot . so If I were to breakdown of the secondary DT switch in that case the server should not be contacted by any host connected to the primary DT switch, although if the primary DT switch were to go fail , the Secondary DT switch will unable to contact the servers so all the clients connected to the Secondary switch should lose connectivity to the servers . Can anyone here help me on this issue I will be really appreciate this effort?

Thanks in advance

Well I suggest you to try and disable not just the ISL but the keepalive links, with the links on the server on Primary switch. Or else you can reboot it to simulate its outage. Hey can you send me the configs so that I can get to the proper conclusion

Thanks for the reply but while I off the DT Secondary switch the primary can route as expected and while the off the DT Primary switch secondary cannot ping anything and
Here is the configuration setting

I think the IP routing and distributed trunking is commonly exclusive. The routing restriction with distributed trunking are switch-wide which that don’t apply on the DT ports only. I suggest you to disable the routing on switch then copy and paste this config
