The following table summarizes scale limitations for the NPB application forwarding features.
| Feature | Sub-Group | Product Scale | Description | 
|---|---|---|---|
| Port Channel | NA | 32 | 
 | 
| Tunnel Termination | Only transport tunnel (GRE/ERSPAN) | 1000 | 
 | 
| Outer VXLAN header (only) | 1000 | ||
| Outer MPLS header (only) | 1000 | ||
| Transport tunnel + Outer VXLAN header + Outer MPLS header | 1000 | ||
| Non-Transport Tunnel | NA | 2000 | |
| Ingress Group | Physical ports and port channels | 256 | The no. of ingress groups on physical port or port channel depends on the physical ports. | 
| Transport tunnels only | 1000 | 
 | |
| Non-transport tunnels only | 2000 | 
 | |
| Route-map or route-map instances | NA | 4000 | The no. of route-map entries in the hardware and limit depends on ACL rules. 
 The route-maps are attached to ingress groups. 
 | 
| Ingress ACL | MAC | 1500 | If the ACL is attached to a route-map which is attached to an ingress group, the entries are programmed to the hardware (TCAM). 
 | 
| IPv4 | 6000 | ||
| IPv6 | 2000 | ||
| Ingress Range support: 
 | NA | 128 | Max. length range match: 128 | 
| Egress Group | NA | 
 | Max. no. of unique egress objects + max. no. of egress-groups with replication cannot exceed 128. 
 Examples: 
 | 
| Egress | NA | 128 | Egress objects limit depends on the SFC table which supports 128 entries. 
 | 
| Egress ACL | MAC | 512 | If the ACL is attached to a listener policy which is attached to an egress object, the entries are programmed to the hardware (TCAM). If an ACL contains x no. of rule entries that are attached to y no. of listener policies, then x * y denotes the consumed TCAM space. | 
| IPv4 | 512 | ||
| Pv6 | 512 | ||
| Egress Range support 
 | NA | 128 | The max. length range match is 128 ACL rules. | 
| Listener Policy | NA | 484 | The no. of listener policy entries in the hardware and limit depends on ACL
                rules. 
 The listener policy is attached to egress objects. Each listener policy can have three instances. 
 | 
| Tunnel Origination | NA | 128 | The hardware supports 512 tunnel origination which is attached to egress objects. 
 | 
| Onboard PCAP Sessions | NA | 10 | |
| VXLAN/MPLS Mirrors | NA | 250 | When configured, a copy of the full untagged VXLAN or MPLS frame is mirrored to the configured egress port without any header termination.
