TCAM is a faster lookup process where the routing tables store access control lists (ACLs), Quality of Service (QoS), and other information related with the upper layer processing. This is faster as it looks for the data as a start and then looks for the respective memory location, unlike RAM storage where memory address is used to search for specific data. The TCAM Utilization page is used to check the percentage of how much TCAM utilities are used and limit the usage for applications accordingly.
In this article the process to view the TCAM Utilization on a ESW2-350G series switch is detailed.
• ESW2-350G Series Switches
• v1.2.9.44
Step 1. Log in to the web configuration utility and choose Status and Statistics > TCAM Utilization. The TCAM Utilization page opens:
• TCAM Utilization — Displays the percentage of the TCAM rules used out of the 510 maximum entries.
• Max TCAM Entries — Displays the maximum number of TCAM rules allowed.
