Chapter 14 Configuring the Switching Database Manager
To configure SDM maximum size for each application region, perform the following procedure,
beginning in global configuration mode:
Command
Step 1
Router(config)# sdm size
region-name
[k-entries] num-of-entries
Step 2
Router(config)# end
The following is an example of limiting the IP-Prefix region to 2K entries:
Router # configure terminal
Router(config)# sdm size ip-prefix k-entries 2
Router(config)# end

configuration mode:
Router # show sdm size
