Hi,

While making node interfaces as a part of pool interface members when is it best to use Etherchannel(FEC).

When i searched for the differences between LACP and FEC i found that FEC "does not negotiate aggregation with the peer or exchange frames to monitor the link" but LACP does; how important is that ?

Isilon 6 node cluster with OneFS 7.0.2.4

Also, my environment has an issue creating multiple subnets on Isilon. We have 2 subnets, subnet0 (default) and subnet1 with different vlan tagging; nodes interfaces are shared across subnets. We were unable to ping subnet1 from a different subnet (we are planning to give 1 subnet for each department)

               Support found that the packets are being dropped by the firewall. This is because packets are coming in to subnet1 with vlan id111 and ROUTED OUT THROUGHT SUBNET0 which has vlan id 110. (this is the default behavior of Isilon, all the packets from different subnets must route through subnet0 that has the default gateway with priority 1) As the tagged vlan id changed on the packets, the firewall is dropping the packets.

The solution provided is 1) Not to share node interfaces across subnets - Cant't do that, we have only 6 nodes and will create min 8 subnets on Isilon for different departments.

2) To create static routes for each subnet so that packets coming in through subnet1 will go out through subnet1 - This can't be done either as each department internally have close to 60 subnets.

Any idea how to configure isilon network configurations with multiple subnets and no static routes ?

Thanks in advance
