Restrictions and Configuration
The number of ASA SMs supported on the chassis for centralized and distributed forwarding is as
follows:
• Centralized Forwarding supports three ASA SM cards per chassis. Central forwarding has an ingress
and an egress supervisor EARL lookup.
• Distributed Forwarding supports four ASA SM cards per chassis. In distributed forwarding, ingress
lookup is done by the line-card, and egress lookup is done by the supervisor EARL.
Restrictions and Configuration
Restrictions
The following restrictions apply to ASA SM:
• ASA SM is only supported on the 7606-S and 7609-S chassis. Support for 7613-S and lead free
version of 7606-S will become available later.
• ASA SM is not supported on Cisco 7603 and Cisco 7604 routers.
ASA Configuration
ASA SM uses one of the following multi-card configurations to scale bandwidth:
• VLAN-based approach: This approach uses multiple ASA SMs per chassis. Each ASA SM is
assigned a distinct set of VLANs. Traffic is assigned to a specific ASA SM based on its incoming
or outgoing VLAN tag.
• Policy-based routing approach: This approach is similar to the VLAN-based approach except that
the supervisor uses a policy based routing (PBR) scheme based on the source of the traffic,
application types, or destination to route packets across multiple ASA SM cards.
