_Attribute	_Values	_Default	_Required	_Description
Lacp-priority	Unint32	32768	N	Defines the default LACP priority for determining which end is master in the LACP relationship.
Aging-time	Int32	300	N	The amount of time to keep a MAC entry in the tables before aging it out.
Bridge-mode	Undefined 8021q 8021ad 8021d	8021q	N	Only 8021q is supported. Unknown bridge type Standard 802.1q single tagged Double tagging with S/C tags. Standard switch with spanning tree prior to 8021q
Block-unknown-unicast	true \| false	False	N	Whether to block flooding of unitcast packets that do not have a known mac binding. When set, device must speak to learn mac address prior to being able to talk to the device. Prior to that time, it will not be able to talk.

Tolt System Bridge config Example

The following example will setthe bridge aging timer to 400 (6.6 minutes) and to meet switch security stigs and prevent flooding when a MAC has not been previously learned.

Command Path – tolt>system>bridge>config>
Module – tolt
Container – system
Container – bridge
Container – config
Types – Example Parameters
- aging-time 400
- block-unknown-unicast true

From the MDS1-ESUA<Config># command line, input tolt system bridge aging-time 400 config block-unknown-unicast true and press Enter.

Input commit and press Enter. Outputs similar to the following are displayed:

MDS1-ESUA<Config># tolt system bridge config aging-time true block-unknown-unicast true <enter> 
MDS1-ESUA<Config># commit <enter>
commit complete
MDS1-ESUA<Config># _
