Scalability Matrix

The following table summarizes scale limitations for the NPB application forwarding features.

Table 1. Scalability matrix
Feature Sub-Group Product Scale Description
Port Channel NA 32
  • Max. no. of static LAGs: 32
  • Max. no. of ports in single static LAG: 64
  • Max. no. of LACP LAGs: 32
  • Max. no. of ports in single LACP LAG: 64
Tunnel Termination

Only transport tunnel (GRE/ERSPAN)

1000
  • dest vtep: 1000
  • Inner SAP TCAM: 2000

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
  • dest vtep: 1000
  • Inner SAP: 2000
  • Limit: 1000
Non-transport tunnels only 2000
  • Max. inner SAP: 2000
  • TCAM: Max. 1000 entries for overlapping or shared entries across features
Route-map or route-map instances NA 4000

The no. of route-map entries in the hardware and limit depends on ACL rules.

  • No. of ACLs: 9500
  • No. of route-maps: 10000
  • No. of ingress groups: 2000

The route-maps are attached to ingress groups.

  • Each route-map can have only one ingress group instance and each instance can have only one ACL. So, only 8000 route-maps are supported.
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).

  • If an ACL contains x no. of rule entries that are attached to y no. of route-maps, then x * y denotes the consumed TCAM space.
IPv4 6000
IPv6 2000
Ingress Range support:
  • IP packet length
  • Source L4 port
  • Destination L4 port
  • L4 port range
NA 128 Max. length range match: 128
Egress Group NA
  • 128 (no replication)
  • 126 (replication)

Max. no. of unique egress objects + max. no. of egress-groups with replication cannot exceed 128.

  • If replication is not enabled, egress group acts as a container and does not consume anything from the hardware.
  • Replication requires at least two egress groups or objects.
  • If replication is enabled, egress group consumes one SFC entry for each group.

Examples:

  • Max. no. of egress groups or objects (with two same egress objects across all egress-groups): 126
  • Max. no. of egress groups or objects (with unique egress object per egress-group): 42

Egress NA 128

Egress objects limit depends on the SFC table which supports 128 entries.

  • Egress groups (with replication enabled) use the SFC table.
  • If replication is not configured, the max. no. of egress objects allowed is 128.
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
  • IP packet length
  • Source L4 port
  • Destination L4 port
  • L4 port range
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.
  • Egress ACLs: 484

The listener policy is attached to egress objects. Each listener policy can have three instances.

  • Max. no. of egress objects: 128.
Tunnel Origination NA 128

The hardware supports 512 tunnel origination which is attached to egress objects.

  • Egress objects limit: 128
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.

  • Max. no. of VXLAN mirrors + max. no. MPLS mirrors: 250
