•

Reboot to Factory Defaults—Reboots the device by using the factory 
default configuration. This process erases the Startup Configuration file and 
the backup configuration file. 

The stack unit ID is set to auto, and in Sx500, the system mode is set to 
Layer 2. 

The mirror configuration file is not deleted when restoring to factory 
defaults.

•

Clear Startup Configuration File—Check to clear the startup configuration 
on the device for the next time it boots up.

If the device is in Native Stacking mode, this button restores factory 

defaults on the entire stack.

Clearing the Startup Configuration File and Rebooting is not the same 

as Rebooting to Factory Defaults. Rebooting to Factory Defaults is more 
intrusive.

TCAM allocation is handled differently in Sx500 and SG500X/ESW2-550X 
devices. The Sx500 has a single TCAM that is used for all routing and ACL rules. 
The SG500X/SG500XG/ESW2-550X devices have two TCAMs; one TCAM is 
devoted to routing and the other is devoted to ACL rules.

When SG500X/ESW2-550X devices are in Hybrid stacking mode, they only have 
a single TCAM (just like Sx500 devices). See 

TCAM entries are divided into the following groups: 

•

IP Entries—TCAM entries reserved for IP static routes, IP interfaces, and IP 
hosts.

•

Non-IP Entries—TCAM entries reserved for other applications, such as 
ACL rules, CoS policers, and VLAN rate limits.

If IPv4 routing is enabled on the device, the following table describes the number 
of TCAM entries used by the various features:
