Ethernet Card Software Feature and Configuration Guide, R7.2
Chapter 15 Configuring the Switching Database Manager
Configuring SDM
Weighted-exact-match region—The weighted-exact-match region consists of exact-match-entries
with an assigned weight or priority. For example, with QoS, multiple exact match entries might
exist, but some have priority over others. The weight is used to select one entry when multiple
entries match.
Table 15-1 lists default partitioning for each application region.
Configuring SDM
This section describes SDM region size and access control list (ACL) size configuration. The commands
described in this section are unique to the switching software. Configuration changes take place
immediately on the ML-100T-8 card.
Configuring SDM Regions
To configure SDM maximum size for each application region, perform the following procedure,
beginning in global configuration mode:
An example of this is shown in Example 15-1.
Example 15-1 Limiting the IP-Prefix Region to 2K Entries
ML_Series # configure terminal
ML_Series(config)# sdm size ip-prefix 2000
ML_Series(config)# end
Table 15-1 Default Partitioning by Application Region
Application Region Lookup Type Key Size Default Size
IP Adjacency Exact-match 64 bits 300 (shared)
IP Prefix Longest-match 64 bits 300 (shared)
QoS Classifiers Weighted exact-match 64 bits 300 (shared)
IP VRF Prefix Longest prefix match 64 bits 300 (shared)
IP Multicast Longest prefix match 64 bits 300 (shared)
MAC Addr Longest prefix match 64 bits 8192
Access List Weighted exact match 64 bits 300 (shared)
