SDM Templates Commands
Dell Networking N2000/N3000/N4000 Series Switches
On Dell Networking devices, the total available H/W route entries are divided
statically (at compile-time) among IPV4 and IPv6 routes. If a switch is
deployed in network environments where no IPv6 routes are needed, then
H/W resources allocated for IPv6 routes are unused.
The Switch Performance Optimization feature enables the operator to
optimize resources for IPv4 only routing environments depending on the how
the switch is used in the network at runtime. The operator can choose
between Ipv4-only (where all the routing table entries are reserved for IPv4
Routes) or IPv4/IPv6 (Default) mode.
Commands in this Chapter
This chapter explains the following commands:
sdm prefer
Use the sdm prefer command in Global Configuration mode to change the
template that will be active after the next reboot. To revert to the default
template after the next reboot, use the no form of this command.
Syntax
sdm prefer {dual-ipv4-and-ipv6 |ipv4-routing} {default|data-center}
• dual-ipv4-and-ipv6 —This keyword filters subsequent template choices to
those that support both IPv4 and IPv6. The default template sets an
nominal set of scaling parameters suitable for most situations. The data-
center template maximizes the number of ECMP next hops.
