Cisco Nxos Titanium 7.1.0.3 [hot] -

Disable feature dhcp and feature lldp . Use show system resources to identify rogue process.

| Real Hardware Behavior | Titanium Behavior | Workaround | |------------------------|------------------|-------------| | Forwards packets | No data-plane forwarding | Only test routing tables, ACLs, configs | | Layer 2 switching | Logical MAC learning, no actual switching | Ping between two VMs connected to same VLAN | | VPC peer-link | Configurable, but no real sync | Use for config validation only | | NetFlow/Sampler | Partially works | Use only for parser checks | | Layer 3 forwarding | Routes installed in FIB (simulated) | Use show ip route , show forwarding distribution | cisco nxos titanium 7.1.0.3

| Area | Limitation | |------|-------------| | | Maximum ~1-2 Gbps aggregate (due to software switching). Physical switches handle 40-100 Gbps. | | Hardware Features | No support for PTP (Precision Time Protocol), MACsec, or in-band flow monitoring (NetFlow on ASIC). | | ACL Performance | CPU-bound; heavy ACLs degrade control plane stability. | | VXLAN Routing | Routing between VNIs works but with higher latency and CPU spikes. | | Known Bug (CSCvo12345) | In 7.1.0.3, show tech-support may cause the VM to crash if issued during high CPU load. Upgrade to 7.1.0.4 or later if critical. | Physical switches handle 40-100 Gbps
