Configuration guidance for multiple VLANs to one-armed connection
Hi - hope this isn't too basic a question, but we're having difficulty getting a configuration to work, and I can't find any specific guidance on certain details. I am working with tech support, and will be asking there, but wanted to pursue it here as well.
We're attempting to attach Big-IP 1600 to a Cisco 2000 series switch; the goal is to aggregate all 4 copper GbEs, to handle both our internal and external VLANs over that single aggregated link.
To do this, we have:
- Set the 4 switch ports to trunk mode, with our 2 VLANs allowed
- Set LACP to active for those switch ports
- Created a port channel, in which all 4 are included
- Connected cables to interfaces 1.1 - 1.4 on the 1600
- Created a "trunk" on the 1600, adding all 4 interfaces
- Created the two VLANs on the 1600, assigning the trunk as a tagged interface
- On the 1600, LACP is set to active, STP to passthrough
On the switch, we're using VPC, so no STP should in fact be occurring - i though passthrough would be innocuous, given that.
We can't see any traffic over the VLANs in question. The self-IPs we assigned to those VLANs aren't reachable from the switch, the switch doesn't appear reachable from the Big-IP. (This switch is fully configured for those VLANs, and other trunk-attached devices [e.g. ESXi servers] absolutely see the VLAN traffic, so nothing that fundamental with the switch config).
Any recommended diagnostic steps? Or does anything sound fishy about our config?
Thank you for any help!
