Configuring UFT Modes
To configure the Unified Forwarding Table (UFT) modes, follow these steps.
1. Select a mode to initialize the maximum scalability size for L2 MAC table or L3 Host table or L3 Route table.
CONFIGURATION
hardware forwarding-table mode
DellEMC(conf)#hardware forwarding-table mode ?
scaled-l2-switch Forwarding table mode for scaling L2 Switch entries
scaled-l3-hosts Forwarding table mode for scaling L3 host entries
scaled-l3-routes Forwarding table mode for scaling L3 route entries
DellEMC(conf)#hardware forwarding-table mode scaled-l3-hosts
Hardware forwarding-table mode is changed. Save the configuration and reload to take
effect.
DellEMC(conf)#end
DellEMC#write memory

2. Display the hardware forwarding table mode in the current boot and in the next boot.

IPv6 CAM ACL Region
The IPv6 ACL CAM region is triple-wide in the platform. You can change the IPv6 ACL region to be double-wide mode. This results in a
better scale of the IPv6 ACL entries.
The IPV6 ACL CAM region can also be shared with the IPv4 QOS CAM region. You can partition the CAM as per the sharing requirements
and both IPV6 ACLs and IPV4 QOS entries are installed on the same CAM region.
Important Points to Remember
• The double-wide group takes up two blocks of FP, but the entries remain at 256.
• When you convert the IPv6 ACL CAM region to double-wide, you can configure only up to 64 bit masks for IPv6 source and
destination addresses in the IPv6 ACL rules. The system rejects the host keyword when you write your ACL rules.
• When you convert the IPv6 ACL CAM region to double-wide, carve the IPv6 CAM region in multiples of two. You can use a maximum
value of eight.
• This feature is supported for IPv6 user ACLs only in the ingress direction
• After enabling the IPv6 ACL optimization and CAM sharing features, reload the system for the CAM sharing feature to work. If you do
not reload, the system does not allow you to boot into the warmboot mode.
• If you enable the IPv6 ACL optimization and CAM sharing features, the system does not allow you to downgrade to Dell networking
version 9.13(x.x) or earlier versions via warmboot.
• When CAM sharing is enabled, one of IPv4 QoS or IPv6 ACL CAM regions must be 0. The other non-zero CAM region is used for
sharing between the entries.
