Switch Database Managment (SDM)
SDM utilise des templates pour allouer les ressources mémoires des switch L2/L3 selon l’utilisation souhaitée :
- Default
- Access
- Routing
- VLANs
SW1(config)#sdm prefer ?
access multicast and qos/acl bias, drop unicast
extended-match Using extended match for unicast routing
routing unicast bias, drop qos/acl
