Provision MAC Address Limiting and Aging

TopreventMACAddressstormsatthecustomerEthernet/Gigabit‐Ethernetports,the

NetVanta800seriessupportsMACAddressLimiting.TheNetVantalearnsMACaddresses

fromtrafficingressingthecustomerinterface;oncetheNetVantalearnstheprovisionedlimit,

itdoesnotallowanyadditionalMACaddressestopasstowardthenetwork.MAC

Address

Limitingcanalsobedisabled.Bydefault,NetVantahasMACAddressLimitingdisabled.

Ifenabled,MACAddressagingcanbeused.Bydefault,theMACAgingtimeoutis5

minutes.TheMACAgingTimeoutcanbesettoanyvaluefrom1to3600seconds.Ifsetto

zero,MAC

Agingisdisabled,andlearnedMACaddressesarelocked.

TosettheMACAddressLimitcountandagingvalues,completethefollowi ngsteps:

1. FromtheEnableprompt,type

configure terminal,andpressENTERtoaccesstheGlo‐

balConfigurationprompt.

2. FromtheGlobalConfigurationprompt,accesstheGigabit‐EthernetConfiguration

promptbytyping

interface gigabit-ethernet 1/0/1,andpressENTERtoaccessthe

Gigabit‐EthernetConfigurationprompt.

3. Type

mac limit <# of MAC addresses>,andpressENTERtosetthemaximumnumber

ofMACAddressesallowedontheselectedinterface,from1to100addresses.

NOTE

TodisableMAClimiting,typeno mac limit,andpressENTER.

4. Type

mac aging-time <timeout_value>,andpressENTERtosettheMACAddress

AgingTimeoutvaluefortheselectedinterface,wheretimeout_valueisthenewtimeout

valueinseconds,between0(MACagingisdisabled)and3600seconds.

5. Type

end,andpressENTERtoreturntotheEnableprompt.
