Selecting the SDM Template
A Switch Database Management (SDM) template is a description of the maximum resources a switch or
router can use for various features. Different SDM templates allow different combinations of scaling
factors, enabling different allocations of resources depending on how the device is used. In other words,
SDM templates enable you to reallocate system resources to support a different mix of features based
on your network requirements.
Note
If you attach a unit to a stack and its template does not match the stack's template, then the
new unit will automatically reboot using the template used by other stack members. To avoid
the automatic reboot, you may first set the template to the template used by existing
members of the stack. Then power off the new unit, attach it to the stack, and power it on.

Table 72: SDM Template Preference
Field
Description
Active SDM Template
Displays the SDM template that is currently active.
SDM Template on the Next
Reload
Select the template that will become active after the next reboot:
•
Dual IPv4 and IPv6 — filters subsequent template choices to those that support
both IPv4 and IPv6. There is only one such template, and it is selected using the
keyword default.
•
IPv4 Routing (default) — filters subsequent template choices to those that
support IPv4, and not IPv6. The default IPv4-only template maximizes the
number of IPv4 unicast routes, while limiting the number of
next hops in each route to 4. The data-center template supports
increases the number of ECMP next hops to 16 and reduces the number of
routes.
•
IPv4 Data Center — this template sets the IPv6 scaling factors to 0 and sets the
IPv4 unicast scaling factors to those used in builds with IPv6. The IPv4 Data
Center template increases the maximum number of ECMP next hops from 4 to
16.
