Have you set the correct SDM template ie. what does "sh sdm prefer" show ?

switch#sh sdm prefer

The current template is "aggregate default" template.

The selected template optimizes the resources in

the switch to support this level of features for

8 routed interfaces and 1024 VLANs.


number of unicast mac addresses: 6K

number of IPv4 IGMP groups + multicast routes: 1K

number of IPv4 unicast routes: 12K

number of directly-connected IPv4 hosts: 6K

number of indirect IPv4 routes: 6K

number of IPv4 policy based routing aces: 0

number of IPv4/MAC qos aces: 1.125k

number of IPv4/MAC security aces: 1K




so i have configured:


switch(config)#sdm prefer dual-ipv4-and-ipv6 default

Changes to the running SDM preferences have been stored, but cannot take effect

until the next reload.

Use 'show sdm prefer' to see what SDM preference is currently active.


i have reloaded


sw3750-bb-pop-si#sh sdm prefer

The current template is "aggregate IPv4 and IPv6 default" template.

number of IPv4 unicast routes: 5K

number of directly-connected IPv4 hosts: 2K

number of indirect IPv4 routes: 3K

number of IPv6 multicast groups: 1.125k

number of directly-connected IPv6 addresses: 2K

number of indirect IPv6 unicast routes: 3K

number of IPv4 policy based routing aces: 0

number of IPv4/MAC qos aces: 1.125k

number of IPv4/MAC security aces: 1K

number of IPv6 policy based routing aces: 0
