Multiple VLAN with Procurve 2810
We have procurve 2810 and currently setup with 3 VLANs.
vlan 2 - 192.168.1.0/24
vlan 3 - 192.168.0.0/24
vlan 4 - 192.168.10.0/24 (through dhcp)
The problem we currently have is that, not all servers in each vlan can talk to each other but they are able to talk to the gateway just fine. The same goes with vlan 4, all servers but 3 are able to get IP address from dhcp server.
Another wierd issue is that, currently all ports are set for auto but there are some using MDI mode and some using MDIX. All cables are premade cat 6 and none should be cross cable.
Can anyone here help me solve these problems ?
Thanks,

Re: Multiple VLAN with Procurve 2810
I would also check thet there are no ACL's in the gateway that might block traffic from those particular servers having the problem.
As for MDI/MDIX, I would like to hear from someone more expert, but I believe that since many servers have NICs able to do the very same autodetection, connecting an autodetecting switch with an autodetecting server can very well give unpredictable, but working, polarity.

Re: Multiple VLAN with Procurve 2810
- Checking that all ports connected to the servers are untagged
- Changing switch ports, in order to see if there is some hardware problem with the ports
- Checking that traffic is not being blocked by the firewall embedded in the server's OS
- Posting the configuration of the switch to this forum.
- Logging into a problematic server (shell if Unix, CMD if windows), ping nearby servers and gateway, doing "arp -a" on windows or "arp -an" on unix, "netstat -rn", and cut/paste the whole session here in the forum.
Good luck,
Bergonz
