Hi there,
I'm having an issue with a very simple setup between two N2024 used purely for iSCSI connectivity between a EqualLogic group members and servers.
I configured the switches as per the "Dell Networking N2000 Series Switch Configuration Guide for EqualLogic SANs" document.
The switches are configured as follows:
- Gi1/0/1 is in vlan 10 and is used for management
- All other ports are in the default vlan
- Te1/0/1 and Te1/0/2 are in an LAG (Po1) and connect the two switches together
- LAG is up at both ends
My problem is that there is no connectivity over the LAG unless I disable STP on the LAG port. I was having problems with the EqualLogic group and narrowed it down to this issue with having STP enabled. Port Fast is not enabled at all.
When STP was enabled, the LAG went into "discarding" state and there was no traffic between the switches. If I disabled STP, the LAG goes into a "Manual Forwarding" state and traffic is passed between the switches. The only links between the switches are the two 10Gb SFP cables which are in the LAG.
There's really very little configuration on the switches, I set them up exactly as described in the Dell document which sets very few options, so it seems odd that there should be an issue with this.
Does anyone have any suggestions as to what might be wrong? I can post any config needed.
Cheers
