18 Configuring MAC
Retention
MAC Retention allows a system of stackable switches to retain the MAC address of the primary switch for
a fixed or indefinite time, even after multiple takeovers. This minimizes the recalculation of protocols,
such as Spanning Tree and Link Aggregation. It also minimizes the updation of tables, such as the Address
Resolution Protocol (ARP) table for IPv4 routing and the Neighbor Discovery table for IPv6 routing.

Note. MAC Retention is only supported on the OmniSwitch 6400 and 6850.
In This Chapter
This chapter describes the basic components of MAC Address Retention and how to configure them
through the Command Line Interface (CLI). CLI commands are used in the configuration examples; for
more details about the syntax of the commands, see the OmniSwitch CLI Reference Guide.
