Deploying an Identity Aware Network

Extreme Networks Application Note
Memory usage in the identity-management process can be viewed using the “show identity-management statistics” command.

“Table 17: Identity Management Database Usage Levels” in the document “ExtremeXOS Command Reference Guide, Software
Version 12.4” provides details on the actions taken when the memory usage level reach high, critical, and maximum levels. The
database memory size can be configured to consume up to 48MB using the “configure identity-management database
memory-size”.
NOTES
The default database size of 512KB is selected to work well for a 48-port fixed configuration edge switch such as Summit X250e-48t,
Summit X450e-48p, etc. However, in chassis switches such as the BlackDiamond ® 8800 series family, and SummitStack, memory
requirements in the MSM modules (in the Chassis switches), Master and Backup nodes (in stacked environments) will increase based
on the density and/or the number of ports used to connect end users and systems. Hence, administrators are urged to take this into
account when tuning/configuring memory size for Identity Management.
