We have a new setup of 2 6509 core switches running VSS and 4 3120 Cisco Blade switches cross stacked. I have run MEC between the VSS cores and the 3120 stack using etherchannel ON mode, bundling 4 sfps, 1 on each 3120. I have the following queries.
- Is using ON mode recmmended for this setup.
- Is pagp not supported for 3120 stacks
- What is the recommended setup for dual active for this setup.
Thanks in advance
