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
To display the number of available TCAM entries, enter the show sdm size command from global
configuration mode:
Router # show sdm size

Configuring Access Control List Size in TCAM
The default maximum size of the Access Control List (ACL) is 65,536 64-bit entries. You can enter the
sdm access-list command to limit the TCAM space for ACLs, as shown in
Table 14-2 Partitioning the TCAM Size for ACLs
Task
sdm access-list num-entries
The following output is an example of configuring 8,192 entries for the ACL region in TCAM:
Router# configure terminal
Router(config)# sdm access-list 8192
Router(config)# end
