I've finally gotten around to setting up SNMP on my cisco server thats running proxmox but have found that neither the main pve nor none of the vm's that are running on it can actually ping the server. They can ping everything else on the network and everything else on the network can ping the cisco server so I know I'm probably just overlooking something dumb but I can't figure out what.
Cisco NIC is set to LOM extended and there is no FW set up between it and proxmox. When pinging the server it shows host unreachable and arp comes back as incomplete, after adding a static arp rule its like the ping is going into a black box as it shows no responses and just 100% loss.
Any help would be appreciated
